Re: The Dining Cryptographers Protocol
My spin on the Dining Cryptographers Protocol is, it's nifty and
theoretically strong, but in practice mixes are better for almost all uses.
If you have N people in a DC-net, you must exchange N bits of traffic per bit
of anonymous message transmitted. If you use mixes and send each message on
M hops, you exchange M bits of traffic per bit of anonymous message
transmitted. N is typically 100-10000, and M is typically 2-10. Mixes
are more efficient.
One advantage of DC-nets is that they're instant; with mixes there must be
some delays in order to accumulate enough cover messages to defeat traffic
