WebMay 5, 2024 · The cryptographic sponge is a popular method for hash function design. The construction is in the ideal permutation model proven to be indiifferentiable from a random oracle up to the birthday bound in the capacity of the sponge. This result in particular implies that, as long as the attack complexity does not exceed this bound, the sponge … WebCA, sponge functions and cryptographic hash functions. 2.1 Basics of CA CA are a discrete lattice of cells. Each cell has a memory element and a next state computation function or rule which is a Boolean function associated with it. The value of the cells get updated based on the CA rule at every clock cycle and this happens in parallel.
