Dining cryptographers networks (or DC-nets) are a privacy-preserving primitive devised by Chaum for anonymous message publication. A very attractive feature of the basic DC-net is its non-interactivity -- no player-to-player communication. A drawback to DC-nets, however, is that malicious players can easily jam them. We present new DC-net constructions that simultaneously achieve non-interactivity and high-probability detection and identification of cheating players. I've always been intrigued by the dining cryptographers problem. Dining Cryptographers Revisited |
