Bash-f: another LRX sponge function
Sergey Agievich, Vadim Marchuk, Alexander Maslau, Vlad Semenov

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...

Analysis of NORX: Investigating Differential and Rotational Properties
Jean-Philippe Aumasson, Philipp Jovanovic, Samuel Neves

This paper presents a thorough analysis of the AEAD scheme NORX, focussing on differential and rotational properties. We first introduce mathematical models that describe differential propagation with respect to the non-linear operation of NORX. Afterwards, we adapt a framework previously proposed for ARX designs allowing us to automatise the search for differentials and characteristics. We give upper bounds on the differential probability for a small number of steps of the NORX core...
