Has anyone implemented a simple anonymous chat system (an anonymous irc) using the technique described in Applied Cryptography 2nd edition? I'm speaking of the Anonymous Message Broadcast documented in section 6.3, it begins on page 137.
A lot of people talk about Dining Cryptographers networks, but I'm not aware of more than an occasional test implementation - the concept is simple, but getting all the details right is a lot of work, including things like collision detection, and there aren't a lot of good uses for the things to motivate development, even though they are basically cool. One design approach is to use IRC; another is email. IRC probably requires that all the participants be on simultaneously, or requires a coordination system to handle whoever's on right now.
Can the same system be implemented using base256 (unsigned char, 8bit ASCII) instead of the simple on/off binary method that is described in the explanation? How would it differ.
Rather than doing Base256, just XOR the bytes; you get the speed of doing things a byte or word at a time, while still getting bitwise changes. # Thanks; Bill # Bill Stewart, +1-415-442-2215 stewarts@ix.netcom.com # <A HREF="http://idiom.com/~wcs"> Defuse Authority!
