Cryptographic checksum

WebA cryptographic checksum function (also called a strong hash function or a strong one-way function) h: A → B is a function that has the following properties: For any x ∈ A, h ( x) is easy to compute. For any y ∈ B ,it is computationally infeasible to find x ∈ A such that h ( x) = y.
