The random oracle methodology
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 WebbI am an enthusiastic Computer Engineer who enjoys real-time problem solving using Software Engineering.
