In cryptography, the dining cryptographers problem studies how to perform a secure multi-party computation of the boolean-OR function. David Chaum first proposed this problem in 1988, and used it as an illustrative example to show it was possible to send anonymous messages with unconditional sender and recipient untraceability. Anonymous communication problems which solve this problem are often referred to as DC-nets.
Despite the word dining, the dining cryptographers problem is unrelated to the dining philosophers problem.

Famous quotes containing the words dining and/or problem:
“Behind her was confusion in the room,
Of chairs turned upside down to sit like people
In other chairs, and something, come to look,
For every room a house has parlor, bedroom,
And dining room thrown pell-mell in the kitchen.”
—Robert Frost (1874–1963)
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
