"WebNov 29, 2024 · When talking about encryption and message authentication codes, a block cipher is a practical instantiation of a pseudorandom permutation family. When talking about hash functions, however, people often talk about block ciphers in the stronger sense of the ideal cipher model, where a block cipher is modeled as a family of random permutations.
