WebbNext, one replaces the random oracle by a \crypto-graphic hash function" (such as SHA), where all parties (including the adversary) have a succinct description of this function. Thus, one obtains an implementation of the ideal system in a \real-world" where random oracles do not exist. The random-oracle methodology has been used quite ... 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 WebbIn the random oracle model (ROM), all parties, including the adversary, are given access to an \idealized" random function (i.e., a random oracle).

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.

Webb$\begingroup$ The question nicely explains a random oracle, but could give a wrong idea of what security in the Random Oracle Model is. Especially, invoking the length-extension property to "prove that SHA-256 is not a random oracle" can be misleading.
