Part of the price of using the remailer > system is that you will occasionally receive a bogus message. I was thinking about digital mix and defeating traffic analysis and realized that the perfect cover for private messages exchanged among remailers -- at least on the Internet -- is to multiplex them into a netnews feed. You would need a new transport protocol that basically handles an encrypted news feed and turns it back into normal NNTP/RFC1036 on the far end, while diverting private mail messages to the appropriate remailing software. If remailers were on large site servers that were set up as news hubs, there would already be a large amount of traffic between any pair of them; insert the private traffic and encrypt/slice/dice the result. This is a low-cost solution since the news has to flow somehow anyway and it is better than just sending around random garbage. -- Michael C. Berch mcb(a)net.bio.net / mcb(a)postmodern.com

Offshore gets Wired
by Duncan Frissell 17 Dec '03

>From the Washington Post - 24 January 1994 INFORMATION HIGHWAY CROSSES THE SEA The Information Highway arrives at ... 14 Caribbean islands. Cable & Wireless (West Indies), AT&T and France Telecom announced a deal last week to build a fiber-optic network across the seabed. Scheduled to be commissioned in early 1995, it will run 1,100 miles from the British Virgin Islands in the north to Trinidad in the south. The cost will be about $60 million. It will be the largest system in the world that employs no "repeaters," units that sit on the ocean bottom and amplify the signal every so often. If ones goes bad, you've got to raise the whole cable and fix it. The cable will have capacity for at least 30,000 simultaneous phone calls, or the equivalent in data, video, you name it. Many islands in the region are trying to upgrade their telecom systems to attract service jobs. Notice that the clerk answering that toll-free vacation reservations number has a Jamaican accent? It might be because your call has rung straight through to Jamaica. One other reason to go with undersea fiber in this region: Hurricanes tend to take out earth stations every few years. --- WinQwk 2.0b#1165

Crypto Experts Oppose Clipp
by Dave Banisar 17 Dec '03

17 Dec '03

Crypto Experts Oppose Clipper More than three dozen of the nation's leading cryptographers, computer security specialists and privacy experts today urged President Clinton to abandon the controversial Clipper encryption proposal. The letter was coordinated by Computer Professionals for Social Responsibility (CPSR), which has long sought to open the issue of cryptography policy to public debate The group cited the secrecy surrounding the proposal, widespread public opposition to the plan and privacy concerns as reasons why the initiative should not go forward. The letter comes at a crucial point in the debate on cryptography policy. An internal Administration review of the issue is nearing completion and the National Security Agency (NSA) is moving forward with efforts to deploy Clipper technology in civilian agencies, including the Internal Revenue Service. CPSR has sponsored several public conferences on cryptography and privacy and has litigated Freedom of Informa- tion Act cases seeking the disclosure of relevant government documents. In one pending FOIA case, CPSR is challenging the secrecy of the Skipjack algorithm which underlies the Clipper proposal. For additional information, contact Dave Banisar, CPSR Washington, DC, (202) 544-9240, <banisar(a)washofc.cpsr.org>. ================================================================= January 24, 1994 The President The White House Washington, DC 20500 Dear Mr. President, We are writing to you regarding the "Clipper" escrowed encryption proposal now under consideration by the White House. We wish to express our concern about this plan and similar technical standards that may be proposed for the nation's communications infrastructure. The current proposal was developed in secret by federal agencies primarily concerned about electronic surveillance, not privacy protection. Critical aspects of the plan remain classified and thus beyond public review. The private sector and the public have expressed nearly unanimous opposition to Clipper. In the formal request for comments conducted by the Department of Commerce last year, less than a handful of respondents supported the plan. Several hundred opposed it. If the plan goes forward, commercial firms that hope to develop new products will face extensive government obstacles. Cryptographers who wish to develop new privacy enhancing technologies will be discouraged. Citizens who anticipate that the progress of technology will enhance personal privacy will find their expectations unfulfilled. Some have proposed that Clipper be adopted on a voluntary basis and suggest that other technical approaches will remain viable. The government, however, exerts enormous influence in the marketplace, and the likelihood that competing standards would survive is small. Few in the user community believe that the proposal would be truly voluntary. The Clipper proposal should not be adopted. We believe that if this proposal and the associated standards go forward, even on a voluntary basis, privacy protection will be diminished, innovation will be slowed, government accountability will be lessened, and the openness necessary to ensure the successful development of the nation's communications infrastructure will be threatened. We respectfully ask the White House to withdraw the Clipper proposal.

O.k. This clipper chip the NSA proposes would have it's keys kep by a separate agency ( yeah, right ). So, until they took you to court, they couldn't really reveal that they knew what all those encrypted transmissions were. So, encrypt with PGP or some other strong crypto, then use the clipper chip. The only way they 'could' know what you were transmitting would be by getting a subpoena and stuff, and then you could say , well, shucks. I forgot the damn number.

REMAIL: Cover traffic
by Hal 17 Dec '03

17 Dec '03

Several people have suggested that the remailers could send bogus messages amongst themselves in order to allow more "confusion and diffusion" of the other messages passing through the remailer network. The remailers could then batch up incoming messages fairly frequently and still have many messages in a batch. The problem with this that I see is that, looking at the remailer network as a whole, you still may have one message in and one message out a short while later. The fact that it was temporarily mixed up with a bunch of other messages doesn't help much if this message is the only one to leave the network. If the Opponent has the ability to monitor all traffic into and out of all nodes of the network (as he would have to do anyway to defeat remailers even without this cover traffic) then he will easily be able to find the messages which are not aimed at other remailers. For cover traffic to be useful, it would have to be indistinguishable from real traffic as it enters and leaves the network. So messages aimed at known "bit bucket" addresses, or at a few cooperating individuals who accept and discard incoming addresses (the same thing, really) will not help. Hal

First off, I think you don't understand fair use -- it is not a right the author grants, EVERYONE has the right to fair-use of ANY copyrighted document. For instance, the Supreme Court recently said that recording material off cable for personal use only was fair-use--giving it to another was not. Secondly, I think there is an implied contract between you and the person that provides the content that you will make it available to others--they would not have any reason to give it to you otherwise.
