WebOne-way permutations are an important cryptographic primitive, and it is not known if their existence is implied by the existence of one-way functions. A trapdoor one-way function or trapdoor permutation is a special kind of one-way function. Such a function is hard to invert unless some secret information, called the trapdoor, is known. WebCryptographic primitives are the random number generators, entropy sources, and basic memory or math operations that are required by the cryptographic algorithms. For …
