Global Encryption Policy
by John Young 17 Dec '03

17 Dec '03

Mike Cobb's and Peter Gutmann's tales of mixed signals from UK and NZ security agencies on exporting crypto demonstrate the same conflicting policies of their nations' governments as do the travails of Zimmermann, Bernstein, Karn and Junger with the USG -- lacking clear regulations, the agencies try bluff and obfuscation. The US move to clarify and tighten regulations in recent ITAR and EAR amendments surely will be emulated by other nations, as promised by The Wassenaar Arrangement. It is part of the major shift of responsibility for dual-use items from national security agencies to those handling economic security, and the guidelines are not as black and white for commerce as they are for state -- or at least not as yet strictly codified, regulated and enforced. However, what is happening with crypto is happening with a wide range of dual-use items, as the half-century old national security policy undergoes a transformation into economic security policy, with the pervasive impact on subsidiary procedures and regulations in security, armaments, intelligence, research, invention, manufacturing, law, finance, politics, education and so on. Note that the World Trade Organization is supplanting the United Nations as a forum for dispute resolution (NY Times, 18 February 1997). For more on these State-into-Commerce policy deliberations see: The GAO/NSIAD report "Exporting Dual-Use Items," 14 January 1997: http://jya.com/9724.htm Export Administration Regulations, with related presidential orders and agency rules and regulations: http://jya.com/eartoc.htm Bert-Jaap's site and a 1996 State Department address on The Wassenaar Arrangement: http://jya.com/dos012396.txt The Defense Trade News from January 1993 to October 1995 on the shift of encryption items from the USML to the CCL: http://jya.com/dtn0193 (+ four) "Redefining Security," The Joint Security Commission's February 1994 report to DefSEc and DCI: http://jya.com/jcs.htm

For the record (which is why I've added coderpunks and cryptography), I have never exported cryptographic software without permission. Everyone to whom I have sent DESKR to has positively affirmed that they are US/Canadian citizens (or US Green Card holders), in the US/Canada, and were aware of, and would abide by the ITAR/EAR restrictions. The source code and executable are draped in warnings of it's non-exportability. I have bent over backwards to do due diligence on this, and am still trying to track down a restricted ftp server which, in my (possibly extreme) opinion, meets my requirements. I have no intention or desire to be the next poster child for crypto export. In other words: I disclaim any responsibility for someone else's exporting DESKR, if that is what this file contains. Someone else may have knowingly broken the export regs, but it wasn't me, nor was it done at my request, or with my approval. Peter Trei trei(a)process.com ptrei(a)acm.org

Prizes, and coordinated vs uncoordinated search, redux.
by Peter Trei 17 Dec '03

17 Dec '03

[Sorry about the long list of lists, but this issue is being discussed in all of them.] 1. Different set of people seem to be working towards different sets of goals, and this seems to be the source of a lot of contention. My personal goal is to promote the easing of US export restrictions on cryptographic software. I regard these restrictions as promoting crime and espionage. They are also driving US jobs overseas, and crippling the US software industry's ability to compete in the world marketplace (yes, I'm an American, and have every intention of promoting my countries best interests). Recently, the US government tightened the rules on cryptographic software export, but left one tiny Devil's bargain of a loophole: if firms would agree in future to compromise the integrity of their products by adding back doors for 'key recovery', then they could export single DES sofware without 'key recovery' until the end of 1998. Clearly, the government's intent is to bribe software developers into 'voluntarily' adopting GAK (Government Access to Keys), when they would never do so without incentive. The rules also require that if either end of a transmission uses a GAK'd product, then both sides of the transmission must be tappable. This makes it difficult for GAK'd and non-GAK'd products to interoperate, and is a wedge to force GAK'd products into even purely domestic communications. I think that this is a horrible idea. One way to fight it is to discredit DES, by showing that any one with sufficient computing resources (or a modest amount of cash) can get single-DES keys broken. If I destroy the market for new DES products, developers will have less incentive to go along with the government's Faustian scheme. The model I am trying to emulate is that of a criminal or spy agency which wishes to decrypt a captured transmission. It's not unusual for such a capture to have a partially known plaintext. In some cases, they may be able to use special hardware to search the keyspace quickly, but if they don't, they could simply put out a message on the sci.crypt: "Tell me what DES key decrypts 0f 1e 2d 3c 4b 5a 69 78 to 'HTTP/1.0' and I'll send you $10,000." This level of attack is available to almost anyone, and I intend to show that it is effective. ------------------ As for the prize money, if the person winning it wants to send it to a non-profit organization, or is contractually bound to dispose of it in some particular way, that's their business. Myself, I'd probably buy a couple really top-of-the-line PCs (for me and my wife), and throw a big party. Thomas S. writes: > 2. What about the developers? They invest an awful lot of time and > effort into this project because they believe in a future of the > internet. The majority would be very unhappy if the money would > be used for personal profit. Speaking as a developer: I've been working on this project in my spare time for about 5 months now. When I talked to RSA about how to best set up the challenge, I *wanted* the money to go to the person finding the key, and I am pleased that that is what they have done. Which particular developers do you claim to speak for, anyway? Can't they speak for themselves? ------------------------- If the coordinated groups don't want to share their keyspace maps with others, that's their business. Effectively, they become just another uncoordinated searcher (though a very fast one). If a coordinated searcher does publish it's map, then people who trust it can use the data to avoid going over old ground. This would speed the search as we near the end, but has very little effect at the beginning. --------------------------- The coordinated groups are still trying to get their infrastructure in place. In the meantime, at my small employer, we are already searching about 10 million keys/sec, with probably twice that being searched by people with my software on the outsde. And I have still to do a general call for participation...

MULTI-JURISDICTIONAL TAXATION OF ELECTRONIC COMMERCE

The Symposium: Billions of dollars of valuable goods and services are sold, exchanged or transmitted electronically. The amount of such commercial activity is expected to grow exponentially in the future. The appropriate taxation of this sector is one of the most significant new tax issues of our day. The International Tax Program and the Society for Law and Tax Policy of Harvard Law School are sponsoring a symposium that will bring together the leading policy makers, academics and practitioners in this field in an effort to help derive uniform tax rules in this challenging dimension of domestic and international taxation. This symposium will consider a wide range of issues, including: **Differences in determining the electronic commerce income tax base. Should source or residence rules be used, or should some form of formulary apportionment be applied? **Problems in imposing retail sales taxes on electronic sales. Should traditional nexus rules apply? **Problems in determining the value added by electronic commercial inputs. Should a tax be determined based on the 'bits' of information? If so, should each 'bit' be valued the same? **Problems involving the harmonization of tax rules. International and sub-national aspects of this problem will be considered. OECD efforts in this area will be contrasted with proposed uniform state legislation in the US. **Throughout the symposium the impact that these tax decisions will have on cross-border investment decisions will be a primary concern. The Goals of the ITP: The International Tax Program continues to sponsor symposiums on topics of critical concern to government and private sector tax practitioners at Harvard University. It is the belief of the Program that such discussions will lead to advances in tax policy, administration and compliance on a global basis. THE MULTI-JURISDICTIONAL TAXATION OF ELECTRONIC COMMERCE presents such a challenge. Basic Income tax objectives such as efficiency and equality of treatment are made more difficult to achieve if the rules of the game are left to develop on an ad hoc basis. Through this forum the International Tax Program hopes to facilitate a meaningful interaction among policy makers around the core issues of taxation and the internet. ========= Schedule: Saturday, April 5, 1997 7:30 - 8:30: Coffee and Registration 8:30 - 9:00: Keynote Speaker, Mr. Jeffrey Owens, Chief, Fiscal Affairs Division: OECD (Paris) 9:00 - 11:30:INTERNATIONAL PANEL: Moderator: Professor Diane Ring, Harvard Law School Speakers: Mr. Bruce Cohen, Attorney-Advisor, Office of International Tax Counsel, U.S. Treasury Mr. Alan S.

-----BEGIN PGP SIGNED MESSAGE----- Is the strength, or lack thereof, of conventional PGP encryption proportional to the length of the conventional password? For example, when I encrypt conventionally, does it make any difference internally (disregarding the ability to guess the password) if I choose to use the pass phrase heyyou, or [Harris$Pizza*Axis/LilburnKfreakmaisUoui@(. Not so much the randomness of my password as the length? Do more characters give the encryption process more to work with? Thanks.
