I. Introduction

In late 1997, at least six bills or amendments on the use of encryption were either introduced or circulated in draft form. Seven congressional committees considered encryption legislation. A clear trend is emerging from these developments. Law enforcement and national security interests favoring restrictions on encryption are quickly growing further apart from civil liberties groups and computer and telecommunications industry associations favoring liberalization of encryption rules. The rifts have grown wide enough to induce at least one interested group to predict that no satisfactory compromise could imminently be possible and to cease advocating the passage of encryption legislation in the short term. This article surveys the current landscape of the encryption debate, and analyzes the major legislative proposals. By identifying their major provisions and policy decisions rather than advocating a particular solution, this article attempts to be a resource for those involved in the ongoing encryption debate.

II. Strong Encryption Backers Grow More Confident of Legal, Political Support

For those favoring the relaxation of crypto regulation, how important is it that criminal penalties not be included? If the alternative were no liberalization at all, would it be preferable to a liberalizing bill with criminal penalties? Click here to comment! On the legislative front, at least three pro-encryption bills were introduced in 1997. These bills aim at substantially eliminating the current restrictions on encryption software and hardware by removing or weakening the current controls on the export of encryption. For the most part, these bills declare the freedom to use and to sell encryption of any type. They also prohibit the government from mandating private sector participation in key recovery or key escrow systems.

The Security and Freedom through Encryption (SAFE) bill, one of the bills under consideration, specifies that the Commerce Department have jurisdiction over the export of encryption products, except where the product is specifically for military use.[1] SAFE also explicitly exempts several types of products from controls, for example, generally available software, public domain software, or products comparable to one available from a foreign supplier. In a concession to law enforcement interests, the bill includes a provision by which the use of encryption "in the furtherance" of a crime would be punishable with a sentence of five years for the first offense and ten years for subsequent offenses. In comparison to other liberalizing bills, this provision has drawn criticism from those advocating the loosened controls. Such critics are uncomfortable with criminalizing the use of encryption because encryption is predicted to be critical to and ubiquitous in the impending information society. Criminal penalties are aimed at the pedophiles and Cali cartels of the world. However, a light sentence other relatively minor crimes (filing improper tax returns, for example) could expand totally out of proportion with its severity if encryption was in any way involved (such as if supporting data was encrypted while being sent to a tax preparer).

Does crypto liberalizing legislation have any place even mentioning key recovery? Even given market demand for key recovery of stored data, and even if the bill only provides safeguards against unauthorized disclosure of keys? Click here to comment! Another bill, titled the Protection of Commerce Online in the Digital Era (ProCODE), prohibits several forms of governmental controls of encryption.[2] Under ProCODE, the government cannot regulate or set standards other than for federal computer systems. The government also cannot set export controls or regulate the interstate commerce in products solely because they include encryption. Unlike SAFE, ProCODE does not include any criminal penalties. Hence, it is the preferred solution of the most hard-line elements of the on-line community.

S. 376, the Encrypted Communications Privacy Act, has thus far received little attention. However, it is the preferred bill of perhaps the most active voice in Congress on internet issues, Senator Patrick Leahy of Vermont, who is its sponsor (incidentally, the bill was named, and is nicknamed ECPA II, in deference to ECPA, the Electronic Communications Privacy Act of 1986, Pub.L. 99-508, of which Leahy was a sponsor). Similar to SAFE, ECPA II not only declares the freedom to use and sell strong encryption products, it also contains criminal penalties for encryption use.[3] ECPA II's penalties, however, are narrower in that they apply only where encryption is used to obstruct, impede or prevent the communication of information to law enforcement in furtherance of a felony. ECPA II is unique among the liberalizing bills in that it explicitly deals with the responsibilities, liabilities and standards for the provision of keys or decryption assistance to law enforcement. Although ECPA II does not require or encourage key recovery, it recognizes that in some cases, entities will turn voluntarily to key recovery solutions to prevent the irretrievable loss of critical data if an employee holding a key is killed, for example, or if she leaves her employer suddenly on bad terms. The bill requires a court order, pursuant to a judicial finding that a) provision of the key or decryption assistance is necessary to obtain the plaintext (e.g. that the plaintext cannot be obtained in any other way) and b) that the government entity is entitled to the information under the wiretap law or ECPA (I) (18 U.S.C. Chapter 119, 121 or section 2703, respectively) or other authorizing law. The bill also sets controls on the disclosure of information and the destruction of key information when the order expires. Finally, the bill sets a tough standard for the provision of decryption information to a requesting foreign government. It requires not only that the foreign country be authorized to intercept the information under its own law, but also that its law provides adequate protection of privacy rights, and that the conduct under investigation would be a violation of U.S. criminal law. The civil damages obtainable for unauthorized disclosures are weighted to deter law enforcement abuses. These damages include lost profits and statutory damages, as well as attorneys' fees, costs and the possibility of punitive damages in some cases.

Notwithstanding the fact that ECPA II and ProCODE have been discussed in hearings, they have not widely been considered viable candidates for passage in the Senate, due in part to the progress of the opposing McCain-Kerrey bill. This may be changing, however, for the Senate Majority Leader Trent Lott (R-MI) recently stated in the Congressional Record that the approach of Senator Conrad Burns (R-MO) "has always been fair and equitable, attempting to balance industry wants with law enforcement requirements." [4] It is unclear, however, whether Lott referred to ProCODE, which is Burns' original proposal, or a compromise proposal Burns made before the Senate Commerce Committee in an attempt to stave off passage of McCain-Kerrey. SAFE, on the other hand, is the primary piece of encryption legislation in the House of Representatives and has been considered by five House Committees (Judiciary, International Relations, National Security, Intelligence and Commerce). SAFE gained its powerful momentum from the fact that at approximately 250 members of Congress are currently co-sponsors of the bill. Assuming that these co-sponsors continue to support the bill substantially as written - there are indications that this may not be - SAFE may still not pass. Without any additional votes from members not co-sponsoring the bill, the 250 votes will still fall shy of the two-thirds majority necessary for the override of a threatened presidential veto.

The House committees, when considering the SAFE bill, made, on the whole, only minor amendments to it. The exceptions were the National Security and Intelligence committees, which rewrote the bill to make it tighten regulations. The Commerce committee, attempted more concretely to address law enforcement concerns without fundamentally altering the bill. Their changes included first a doubling of the criminal penalty for the use of encryption in furtherance of a crime, and the specification that any licensure system for encryption products cannot require key escrow. Second, the amendment provided sturdy liability exemptions for persons providing law enforcement access to keys or plaintext. Finally, the amendment would have established a center to study ways of effectively decrypting data. The Committee mandated a) studies both on the possible impact of a mandatory key recovery system, and on impediments in other countries to trade in encryption technologies, and b) regular reports to Congress of instances where encryption has interfered with the enforcement of federal criminal laws. Assuming arguendo that a political compromise is possible, the Commerce committee's version of SAFE might provide the model. The amendment provides stringent, but not fundamentally coercive disincentives for antisocial uses of encryption - perhaps, however, the broad sweep of the criminal penalties could be narrowed slightly by making them apply only to non-key recovery encryption. Alternatively, the tighter language from ECPA II might be incorporated. The amendment also demonstrates genuine efforts to compensate for the inability to decrypt encrypted communications without compromising the security of the system.

Is Bernstein destined to be overturned? In either case, how relevant is it to the ongoing debate? Click here to comment! Outside the halls of the Capitol, crypto friends and foes alike were startled by the decision of Judge Marilyn Hall Patel, a federal district court judge for the Northern District of California, that encryption software is protectable first amendment speech and that the controls forbidding its export are unconstitutional.[5] Bernstein v. U.S. Department Of State involved a professor who had developed an encryption algorithm which he wished to publish in a book, along with a diskette containing the source code for the algorithm. The State Department ruled that the software was subject to export restrictions because, as an algorithm with a key length greater than 40 bits, it was a "munition" under ITAR (International Traffic in Arms Regulations). Reiterating her earlier decision in the case that encryption software is expressive speech, Judge Patel observed that "the most common expressive activities of scholars -- teaching a class, publishing their ideas, speaking at conferences, or writing to colleagues over the Internet -- are subject to a prior restraint by the export controls when they involve cryptographic source code or computer programs."

Certain aspects of the export regulations seemed particularly to disturb the court. First, the Court attacked those provisions, on the one hand, which exempt cryptographic source code published in book form, while on the other hand, restricting the same source code when embodied in an electronic text file on a disk. Becoming one of the first courts to interpret Reno v. ACLU, Judge Patel interpreted the landmark decision as decreeing "the distinction between print and electronic media increasingly untenable" with regard to the protection afforded by the First Amendment.[6] "[N]ational security alone is insufficient without more" to justify a prior restraint on speech, Patel further decided. She cited in support of this holding a majority of justices in the splintered opinions of the Pentagon Papers case.[7] Third, Patel decided that some form of judicial review would be necessary to support a prior restraint on the export of cryptographic software.

Judge Patel suggested, however, a possible constitutional method for regulating encryption exports: regulation on the basis its "secondary effects." Although this exception has only been applied to restrictions on sexually explicit speech, in such cases as Young v. American Mini-Theaters, Inc. and Renton v. Playtime Theaters, Inc., zoning ordinances aimed at curbing the blight, crime and reduced property values caused by porn shops have been upheld.[8] Despite the fact that Reno v. ACLU rejected this line of cases as an analogy for content restrictions on the internet as a whole, such secondary effect regulation might be more apt where applied to a concrete technology with specifically identifiable effects. The Bernstein case was granted an expedited appeal to the Ninth Circuit and was argued before a three judge panel of that court on December 8, 1997. Observers have suggested there is a strong likelihood of the decision being overturned, if not by the circuit court, then by the Supreme Court which has, of late, been in particular disagreement with the decisions of the Ninth Circuit. However, at the appellate arguments, the justices reportedly were skeptical about the government's argument that the regulations do not stifle speech because they merely regulate one possible medium for that expression.[9]

In addition to domestic developments on the judicial and legislative fronts, the European Commission issued a communique on October 8, which advocated a policy for member nations regarding the use of encryption for commerce and security.[10] While concerned with the recognition of encryption techniques for digital signatures and the regulation of Certificate Authorities for authentication purposes, the communique concurrently addressed encryption used for security and the balance of commercial, privacy and law enforcement concerns about its proliferation. It must be noted, however, that the Commission does not itself have jurisdiction over export controls in Europe.

For years, U.S. proponents of strong cryptography have argued that encryption controls would be ineffective because foreign vendors would be able to offer comparable products, thus creating an opportunity for foreign software companies to chip away at U.S. domination of the software industry. Seemingly expressing the EC's willingness to leap at that opportunity, one of the goals in issuing the communique was that of "stimulating a European industry for cryptographic services and products." The EC feels that growing demand for encryption products "provides substantial opportunities for the industry and job creation in Europe," and that, "The exclusive character of encryption [as both a military-dominated and U.S.-dominated technology] belongs to the past."

Most importantly, the communique stated a very different opinion from that of the Clinton Administration concerning whether encryption controls could be effective at all. Citing several widely circulated reports on the technical weaknesses of key recovery systems and the ineffectiveness of encryption controls, the Commission found that, "Any involvement of a third party in confidential communication increases its vulnerability." The communique came to the conclusion that "restricting the use of encryption could well prevent law-abiding companies and citizens from protecting themselves against criminal attacks. It would not however prevent... criminals from using these technologies."

These limitations, while down-played by the Clinton Administration, are not news. The U.S. government has responded by pressing all the more strongly for encryption controls and law enforcement access in order to increase the likelihood that the benefits would outweigh the disadvantages. This is another respect in which the EC differed with the U.S. The Commission suggests that a minimalist approach to regulation is necessary. "National restrictions must respect the principle of proportionality (be appropriate, effective and not go beyond what is necessary for attaining the objective pursued)." To this end, the communique also discusses other ways of obtaining adequate intelligence in lieu of governmental access to keys. For one thing, traffic analysis, or intelligence gathering based on data showing who is communicating to whom and when, is increasingly becoming a gold-mine of information for law enforcement. The Commission noted that, if the availability of encryption raises criminal confidence in the security of their communications, the increase in electronic communications traffic will offer better information for law enforcement. Even considering access to the content of communications, the communique noted, "The ultimate objective for government agencies is to see plaintext and not necessarily to have access to keys. . . . Information, even encrypted for communication, can often be found unencrypted at the source. . . for instance with banks, shops, travel agencies involved in communication with a suspect, or can be tapped unencrypted at certain points in a communication link." According to the Commission's reasoning, the requirement or encouragement of the provision of keys to law enforcement may be a superfluous intrusion into personal privacy.

The strong House support for SAFE, the Bernstein decision, and the growing appearance of a rift between the Clinton Administration and Europe over encryption policy have instilled a certain degree of confidence in those corporations and civil liberties groups that want to see encryption rules drastically liberalized. This confidence, along with vehement opposition to restrictions from prominent elements of the internet community, has perhaps made these parties less receptive to compromise proposals. Likewise, the strength of SAFE and the possibility of the export scheme's unconstitutionality have also prompted law enforcement and national security groups to toughen their stance, and to be less willing to compromise.

III. FBI and NSA Raise Demands for Encryption Restrictions

Historically, for three years after the original Clipper Chip proposal was made in 1993, the Clinton Administration's encryption policy was based on encouraging (although critics claimed `coercing' would have been a better verb) the use of key recovery or key escrow. This encouragement took the form of making key recovery or key escrow a prerequisite for a) the export of software or hardware which included encryption (manufacturers would otherwise have to produce separate `domestic' and `export' versions of their product) b) the use of encryption by the government or in communication with the government (using the government's position as the largest purchaser of computer products as leverage) or c) the use of encryption on government-funded networks (which would include, for example, the proposed Internet II). This changed in late 1996 when, as part of the transfer of jurisdiction over encryption exports from the Department of State to the Department of Commerce, another `encouragement' for the development of key recovery products was added. Any software company would be allowed slightly more rigorous encryption (56-bit versus 40-bit) provided that the company promised, and then continued, to develop encryption products with key recovery features for sale by the end of 1998.[11] Even through the present day, no government proposal has required the use of key recovery encryption software for general domestic use although restrictions exist that might require it of individuals - government employees, for example - in certain situations.

The spring spring and particularly the summer of 1997, marked the introduction of three bills aimed at placing further restrictions on non-key recovery encryption, or at least aimed at trying alternate ways of eliciting participation in a key recovery infrastructure. First, S. 909, known for its sponsors as the McCain-Kerrey bill, encourages the use of key recovery by making it a prerequisite to obtaining a digital "certificate" from a government-registered Certificate Authority.[12] Critics have complained that this is an inappropriate linkage between the use of encryption for confidentiality, and the use for authenticating the author of a document. Cryptographic authentication is technically the reverse of the cryptographic scrambling, for the sender uses her private key to sign an electronic message and the recipient uses the sender's public key to verify the message. A Certificate Authority is a known or reputable entity which vouches in the `certificate' portion of the signature that the private key in fact belongs to the person who is listed as the owner (this certification is theoretically verified through security procedures such as checking a driver's license or other real world i.d.). Certificate Authority services are generally thought to be an essential element of more secure on-line transactions in the future. Coupled with powerful legal incentives for authorities to become government-registered, it is thought that while participation is technically voluntary, being unable to use a certificate from a registered authority would make individuals second class citizens in the information economy. In addition, the bill stipulates criminal penalties for the use of encryption in committing crimes. Although hailed by its backers as a compromise between a draft Administration proposal circulating at the time of the bill's introduction and pro-crypto bills such as SAFE, critics were eventually successful in the press in portraying the McCain-Kerrey bill as a carbon copy of the Administration's proposal.

Are there any legal controls (i.e. short of encouraging or mandating key recovery) which might substantially satisfy law enforcement concerns? If not, is there any room for law enforcement to compromise? Click here to comment! Within days of its introduction, the McCain-Kerrey bill was approved by the Senate Commerce Committee. However, at hearings in July before the Judiciary Committee, criticism came from not only from opponents of encryption controls, but from supporters as well. Senator Charles Grassley (R-IO) mentioned a report of a teen boy who had been abducted and killed. It was thought that the boy had mentioned the name of his abductor in his diary which was kept in encrypted form on his personal digital assistant (or PDA). Hearing witnesses, including Senator Kerrey and FBI Director Louis Freeh, as well as other Senators, pointed out that neither the existing law nor the McCain-Kerrey bill would have affected the case because it involved the domestic use of encryption. As the encryptor was the victim, not the perpetrator, criminal penalties would not have applied either. Senators from both parties favoring tougher encryption controls were uneasy that the bill under consideration would not have brought critical and, perhaps in other cases, lifesaving evidence such as the boy's diary within the reach of law enforcement. As the debate progresses, it would not be alarming to see some of these Senators support proposals which would address this problem.

This tacit endorsement apparently did not go unnoticed by the FBI, even though Director Freeh indicated that, at that time, he was not asking for domestic controls on encryption. Within weeks of the Senate Judiciary Committee hearings, much more restrictive proposals appeared. As the House continued consideration of the SAFE bill, the Judiciary and International Relations committees passed it essentially intact, and it was referred to the National Security Committee and the Intelligence Committee. The National Security Committee altered the SAFE bill so as to retain and to explicitly codify the export controls.[13] The amendment added criminal penalties for the use of encryption and set up a system for annual review of the acceptable level of non-key recovery encryption, which would initially be set by the President after enaction. One notable feature of the National Security amendment was that while the Secretary of Commerce would implement the controls and possess authority to issue licenses, this power would be exercised with the concurrence of the Secretary of Defense, thus giving the Defense Department a veto over such decisions. Furthermore, these decisions would be exempted from judicial review.

The Intelligence Committee completely rewrote the SAFE bill (as the Washington saying goes, the seven most dreaded words on Capitol Hill are "amendment in the nature of a substitute"). The extensive and carefully crafted amendment has changed the face of the encryption debate. The Intelligence Committee SAFE amendment became the first proposal to mandate the inclusion of key recovery in all encryption software "manufactured for distribution," distributed, sold or imported into the US.[14] These restrictions would become effective February 1, 2000. Arguably, the bill would also apply extraterritorially to any entity with a US presence that "sells in... foreign commerce any encryption product" even if the product was never in the US and the sale occurred abroad. Equally important, the amendment removed any differences in the treatment of weaker encryption; the key recovery provisions would apply to 128-bit systems and to 40-bit or weaker systems equally. The amendment would not affect the use of encryption, so any products sold before the deadline could continue to be used. Furthermore, it would arguably be permissible for an entity to manufacture a product as long as it was not sold and not "for distribution," for instance, if it was for free internal company use.

The export of encryption products likewise required that there either be immediate access to plaintext or key recovery. However, a cryptic provision (§ 302b) indicated that these capabilities, in products for export, could be deactivated by default to be enabled at the end user's option. A product with the dual capability of running in `key recovery mode' or `non-key recovery mode' might be ruled out by the restrictions on manufacturing and distribution mentioned above, but would arguably be permissible for export. Inexplicable in the light of its contradiction with past government policy, this provision, on its face, might allow companies to offer tougher encryption abroad than in the U.S. This provision (along with its permissiveness as to the use of prior products) thus begs consideration of an alternate interpretation: that it is a weaker instrument designed to proliferate products with key recovery options, rather than a bill to eradicate products offering non-key recovery encryption. Even if semantically colorable, such an interpretation seems unlikely. Interpreting section 302b as a drafting error is more credible.

Several other sections of the Intelligence Committee amendment indicate its truly comprehensive nature. First, the criminal penalties in the amendment go further than any others in specifying that the sentence is to be served consecutively, not concurrently, with the sentence for the underlying offense (although it also specifies that the use of encryption alone is not probable cause to believe a crime is being committed). Second, unlike the National Security bill, the Secretary of Defense does not have a veto over Commerce Department decisions. However, there is to be "close coordination." Third, while the Intelligence Committee bill does not condition the issuance of cryptographic certificates on key recovery participation (as the McCain-Kerrey bill does), brief references to Certificate Authority regulation would probably allow the Commerce Department to set such a prerequisite. Fourth, the amendment sets out the duty of network service providers to provide key recovery on all encryption services they offer, as well as extensive rules for the federal procurement and funding of encryption products including key recovery.

The Intelligence amendment does have lengthy limits on unauthorized access to decryption information or disclosure of decrypted information or keys. However, most of these controls may be undermined by extensive defenses for compliance with the act, good faith reliance on legal authority, sovereign immunity, and so on. Similarly, a court order is required to obtain key information, and law enforcement officials must have lawful authority to get the underlying data to be decrypted. The strictness of this requirement is also undermined because judges apparently lack discretion to deny a request for a court order when the government attorney demonstrates any factual basis for the relevance of information sought to the investigation and the officer is legally entitled to such plaintext or keys. Overall, these professed safeguards may just be paper tigers.

Senator Lott, in his recent statement on encryption called the FBI's domestic key recovery proposal (and by implication the similar Intelligence Committee amendment) a "large unfunded mandate on our high technology firms" and "simply wrong."[15] Furthermore, Lott claimed that, "I have learned that even the administration does not support this new FBI proposal." While this is not the first indication of policy disagreements between the White House and the FBI, it is the first indication that FBI may not be the Administration's voice on the encryption issue.

IV. Conclusion

In short, the debate over encryption regulations, which has been at a stalemate since the days of the Clipper Chip, seems no closer to resolution. On the one hand, the FBI and the law enforcement community appear to have sensed support for a proposal they had not dared to offer in the past: domestic mandatory key recovery encryption. On the other hand, pro-encryption entities, from the computer industry to civil liberties groups, seem emboldened by the breadth of congressional support for the SAFE bill. The Bernstein decision and the European Commission's recent findings have only provided them more ammunition in the debate. No less antagonistic, these two sides have each upped the stakes. This, combined with the urgent need for tougher encryption for on-line commerce and electronic security, makes the issue more explosive and less predictable than ever.

Focus
Encourages the use of Key Recovery by making Key Recovery use a prerequisite to obtaining a digital "certificate" from a government-registered Certificate Authority. Provides strong incentives for CAs to become government-registered. Strengthens existing export control regime which encourages the inclusion of key recovery in software with encryption features by restricting the export of encryption software without key recovery to weak levels of security. Mandates that all encryption software manufactured for distribution, distributed, sold or imported into the US after 1/31/2000 include key recovery.

Arguable extraterritorial application to any US entity that "sells in... foreign commerce any encryption product" even if product was never in US and sale occurs abroad.

Prohibits domestic use/sale of encryption without key recovery? No.No Yes: prohibits sale/distribution.

Permits use of products sold before deadline. Also, items manufactured, but not for distribution or sale, (e.g. for internal use by the same entity) are arguably permitted.

Restricts domestic use/sale of encryption without key recovery? Yes - if key recovery not used, no certificate from registered CA. No (Prohibits mandatory use of key escrow) [See above.]
Criminal Penalties for the use of encryption related to a crime? Yes. If used in furtherance of a crime, up to 5 years first offense, 10 yrs thereafter or fine or both. Specifies that the use of encryption alone is not probable cause to believe a crime is being committed. Yes. If used in furtherance of a crime, up to 5 years first offense, 10 yrs thereafter, or fine or both. Yes. If used in furtherance of a crime, up to 5 years first offense, 10 yrs thereafter or fine or both. Terms to run consecutively, not concurrently with the underlying sentence. Specifies that the use of encryption alone is not probable cause to believe a crime is being committed.
Export Controls
Authority over export controls/licenses: Sec. of Commerce in consultation with relevant executive agencies. Secretary of Commerce with concurrence of Secretary of Defense Sec. of Commerce in "close coordination" with Secretary of Defense.
Decisions of Executive Branch are judicially reviewable? Certain determinations (harm to national security etc.) not reviewable. No.No.
Encryption products may be controlled even if not on munitions list? N/AYes Yes.
Government sets level of (non-key recovery) encryption which may be exported? Yes but even products under that level must undergo a one time review (and may not be exported to countries ruled ineligible to receive such products). Initially 56 bit DES or equivalent. Yes but even products under that level must undergo a one time review (and may not be exported to countries ruled ineligible to receive such products). President sets initially w/in 30 days of enactment. No. All encryption products exported after 1/31/2000 must include immediate access to plaintext or key recovery and must undergo a one time review (and may not be exported to countries ruled ineligible to receive such products). However, for export, decryption capabilities can be off by default to be enabled by purchaser (§302b).
Review of permissible encryption level thereafter? President reviews at least annually. In addition, President shall increase level if he finds similar products widely available from other nations. President reviews at least annually. Note: new level doesn't take effect for 60 days, not counting when Congress is not in session. N/A
President can waive provisions of the export controls in the interest of national security? Yes.N/A Yes.
Separate treatment for telecommunications products? No.N/A Yes.
If so, may communications products be exported without key recovery? N/AN/A Yes, but Secretary shall authorize export without decryption capabilities only if 1) information recovery requirements would disadvantage US exporters and 2) exports would not create a risk to the foreign policy, non-proliferation, or national security of the US.
Separate treatment for certain institutions? Yes. Expedited review for use of products by qualified banks, health care providers, subsidiaries of US companies or others specifically authorized by Sec. of Commerce. N/AYes. Expedited review for use of products by qualified banks, subsidiaries of US companies or others specifically authorized by Sec. of Commerce.
Specifies Penalty for unauthorized export? Yes. Up to 5 years per occurrence. No.No.
Government Registration of Certificate Authorities and Key Recovery Agents
Government to issue regulations for creating key management infrastructures? YesN/A Yes, may promulgate regulations establishing standards. Private sector participation voluntary.
Government to offer registration for certificate authorities and key recovery agents? YesN/A Yes, government may offer registration under standards set by Secretary of Commerce. CAs and KRAs may identify themselves as being federally registered. No further specifics.
Issuance of Certificates conditioned on use of key recovery? Yes, or alternate arrangements for timely access to plaintext of data without notice to subject. N/ANot mentioned, required or prohibited. Presumably standards could condition issuance of Certificates on use of key recovery.
Key Recovery/Key Management Infrastructure Issues
Unauthorized access to or decryption of data or communications prohibited? Yes, intentional access unlawful:

- without lawful authority

- exceeding lawful authority

- breaking encryption code without authority to violate privacy or security or property rights

- disclosing decryption information in violation of the Act.

N/AYes, intentional access unlawful:

- without lawful authority

- exceeding lawful authority

- breaking encryption code without authority to violate privacy or security or property rights

- disclosing decryption information in violation of the Act.

Third-Party Liability for encryption?N/A N/AIllegal to assist in or facilitate encryption knowing that such data are to be used in furtherance of a crime.
Penalty for unlawful access as above:up to five years or fine or both. N/Aup to 10 years or fine or both.
Liability Exemptions for persons providing law enforcement access to plaintext? N/AN/A Yes, unless person is not authorized by court order to disclose the information.

Compliance with the Act is a complete defense.

Participation in government established key management infrastructure is evidence of reasonable care.

Good faith reliance on legal authority is a complete defense.

Sovereign immunity is not affected.

Sale of Encryption products w/out key recovery illegal? N/A (No.)N/A (No.) Yes after 1/31/2000. Must enable immediate decryption or access to plaintext. Penalty up to 5 years or fine or both (presumably per offense).
Standard for products providing access? N/AN/A "Duly authorized"
Service Providers providing encryption must use key recovery? N/AN/A Yes after 1/31/2000. Must enable immediate decryption or access to plaintext.
Service Provider Standard for providing access: N/AN/A Upon receipt of court order or warrant.
Manufacture/ Distribution/ Importation

requires key recovery?

N/A (No.)N/A (No.) Yes after 1/31/2000 unless product can only be used with systems that provide access or otherwise meets technical requirements. Must enable immediate decryption or access to plaintext without knowledge or cooperation of the person being investigated.
