WebDec 14, 2024 · A DC-net allows to send and receive messages anonymously using an arbitrary communication network, and it is proved to be unconditionally secure and untraceable. However, it requires a reliable broadcast network. WebThe Dining Cryptographers protocol is a multi-party protocol for untraceable communication that offers information-theoretical security and does not require a trusted third party. For many years this protocol was …

The Dining Cryptographers Problem

WebOct 3, 2024 · Computer scientist David Chaum offered this example in 1988 as the basis for an anonymous communication network; these networks are often referred to as DC … 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 unconditional … See more Three cryptographers gather around a table for dinner.
