Dining Cryptographers Protocol (Paperback)

High Quality Content by WIKIPEDIA articles! The dining cryptographers protocol is a method of anonymous communication. It allows for any member of a group to multicast data to every other member of the group. Though the broadcast is public, the protocol guarantees that its sender remains anonymous. This protocol allows only for one member of the group to transmit data during any given round. The method is as follows: three or more cryptographers (nodes) arrange themselves around a circular dinner table (ring network), with menus (encrypted links) hiding the interaction of each pair of cryptographers. Each cryptographer secretly writes down a bit (zero or one) and shows it to every other cryptographer. Then, each cryptographer computes the xors of their own number and each of the other cryptographers' numbers. That is, if the bit the cryptographer is shown is the same as theirs the result is 'zero', and if they are different the result is 'one'.
