Bash-f: another LRX sponge function

Sergey Agievich, Vadim Marchuk, Alexander Maslau, and Vlad Semenov

Abstract

We present the Bash family of hashing algorithms based on the sponge paradigm. A core element of this family is the Bash-f sponge function which refers to the LRX (Logical-Rotation-Xor) class of symmetric cryptography schemes. We describe the components of Bash-f: a nonlinear mapping, linear diffusion mappings, a permutation of words of a hash state. For each component, we establish reasonable quality criteria as detailed as possible to make the choice of the component maximally objective and transparent.

Note: Minor corrections + a description of the overall hashing algorithms
