WebbThe Random Oracle Model. A popular methodology for designing cryptographic protocols consists of the following two steps. One first designs an ideal system in which all parties (including the adversary) have oracle access to a truly random function, and proves the security of this ideal system.

The idea is a simple one: namely provide all parties of a protocol – good and bad alike – with access to a (public) function h and then prove the protocol to be correct assuming that h maps each input to a truly random output, i.e., it behaves like a truly random oracle. highgrove cotes du rhone
