"WebJul 16, 2024 · This is Shannon's confusion and diffusion principle. The best theoretical way to mangle the input bits (it's all a question of bit mangling) is to use a look up table to replace the incoming byte with it's stored value, as in x = S [ x] with S populated with random numbers. For a byte that's great. " - Cryptography confusion and diffusion
