Cryptographic sponge functions

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 …

WebSponge Functions in a Nutshell. As the name implies, a sponge function is a computer routine that soaks up input much like a sponge does. No matter how much data you push … WebThe sponge construction for hash functions. P are input, Z are hashed output. The unused "capacity" c should be twice the desired resistance to collision or preimage attacks. SHA-3 uses the sponge construction, [13] in which data is "absorbed" into the sponge, then the result is "squeezed" out.

WebThe sponge construction is a permutation-based mode for cryptographic hashing. It was rst introduced by Bertoni et al. [13], and it quickly gained in popularity, in particular in light of the SHA-3 competition [33], which was won by the Keccak sponge function [11]. The sponge operates on a b-bit state, which is split into a WebMar 11, 2024 · Practically, both are considered cryptographically secure. So, when wanting arbitrary length of output, you'll have to decide what sponge function you want to use. Looking at Gimli, I'ld like to note that there are other sponge functions out there which are suitable for cryptographic purposes too.
