A sponge function is built from three components: a state memory, S, containing b bits,a function $${\displaystyle f:\{0,1\}^{b}\rightarrow \{0,1\}^{b}}$$a padding function P S is divided into two sections: one of size r (the bitrate) and the remaining part of size c (the capacity). These sections are denoted R and C … See more In cryptography, a sponge function or sponge construction is any of a class of algorithms with finite internal state that take an input bit stream of any length and produce an output bit stream of any desired length. … See more Sponge functions have both theoretical and practical uses. In theoretical cryptanalysis, a random sponge function is a sponge construction where f is a random permutation or … See more
