Hash Functions

Hash Functions. A hash function H accepts a variable-length block of data M as input and produces a fixed-size hash value h = H( M ) Principal object is data integrity Cryptographic hash function An algorithm for which it is computationally infeasible to find either:

HASH Functions

HASH Functions. Hash Functions. condenses arbitrary message to fixed size h = H(M) usually assume hash function is public hash used to detect changes to message want a cryptographic hash function computationally infeasible to find data mapping to specific hash (one-way property)
