WebInformally, it solves the following problem: if a group of dining cryptographers are told that their restaurant bill has been paid and they want to establish whether it was paid by one of them or by an external party, how can a payer inside the group reveal the fact that they paid without also disclosing their identity? In cryptography, the dining cryptographers problem studies how to perform a secure multi-party computation of the boolean-XOR function. David Chaum first proposed this problem in the early 1980s and used it as an illustrative example to show that it was possible to send anonymous messages with … See more Three cryptographers gather around a table for dinner.

WebThe dining cryptographers network (or DC-net) is a seminal technique devised by Chaum to solve the dining cryptographers problem — namely, how to send a boolean-OR bit anonymously from a group of participants. In this paper, we investigate the weaknesses of DC-nets, study alternative methods and propose a new way to tackle this problem. unverified entity listWebDining Cryptographers Problem , after his intro-ductory example.
