It works as follows:\n\nA number of cryptographers are dining at a circular table. At the end of\nthe meal, the waiter is summoned and asked for the bill. He replies,\n\"Thank you, sir. The bill has been paid.\" The cryptographers now have the\nproblem of working out whether someone at the table paid the bill, or\nwhether the NSA has paid it as some sort of veiled threat. The protocol\nproceeds.\n\nEach cryptographer flips a coin, and shows the result ONLY to the\nparticipant on his RIGHT. Each cryptographer then compares his coin with\nthat on his LEFT, and raises his hand if they show different faces. If any\nparticipant paid the bill, he \"cheats\" and does the opposite, that is, he\nraises his hand if the coins show the same face. Now, the hands are\ncounted. An odd number means that someone at the table paid the bill. An\neven number means that the NSA paid.","flavors":[],"html":"https://daemonports.org/dragonfly/security/p5-Crypt-Dining/","kind":"port","lastUpdate":null,"license":null,"maintainer":"perl@FreeBSD.org","name":"p5-Crypt-Dining","newest":true,"newestVersion":"1.01","noVulnData":false,"origin":"security/p5-Crypt-Dining","otherSystems":[{"maintainer":"perl@FreeBSD.org","newest":true,"origin":"security/p5-Crypt-Dining","path":"/security/p5-Crypt-Dining/","system":"FreeBSD","version":"1.01_1"},{"maintainer":"perl@FreeBSD.org","newest":true,"noVulnData":true,"origin":"security/p5-Crypt-Dining","path":"","system":"GhostBSD","version":"1.01_1"}],"packages":null,"pkgName":"p5-Crypt-Dining-1.01_1","related":null,"repository":"DPorts","requiredBy":[],"requiredByCount":0,"runDepends":["lang/perl5.36","net/p5-Net-Address-IPv4-Local","security/p5-Crypt-Random"],"status":null,"system":"dragonfly","systemLabel":"DragonFly","version":"1.01_1","versions":null,"vulnerabilities":null,"www":"https://metacpan.org/release/Crypt-Dining"}
