WebbDespite this, the random oracle methodology has proved extremely useful in the analysis of cryptographic schemes. A proof in the random oracle model indicates that a scheme is not essentially ﬂawed in the sense that an attacker, in order to be successful, should use the hash function in a non-generic WebbThe random oracle model was introduced by Bellare and Rogaway [ 2 ]. 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.
