NODE c992c4b1message splitting for better mixing?
jim@bilbo.suite.com (Jim Miller)Mon, 25 Apr 94 15:30:49 PDT
A variation of the many "send bogus messages through the remailer"
ideas...
The idea:
1) write sender-side code to split message into N parts and send each
part through a different remailer chain.
2) decrypt the parts as they arrive as per normal encrypted remailer
messages.
3) write receiver-side code to detect "a part" and stuff it in a file
until the remaining related parts arrive. When all related parts
have arrived, present the complete message to receiver.
Why? To increase the number of "messages" flowing through the
remailers to make traffic analysis more difficult.
Comments welcome.

Would seem to be a mild nuisance to implement, but probably be quite
effective - particularly if the pieces were 'masked' as uuencoded chunks
of, say, a .GIF or something :-)
