Arion: Arithmetization-Oriented Permutation and Hashing from Generalized Triangular Dynamical Systems

Arnab Roy, Matthias Johann Steiner, Stefano Trevisani

In this paper we propose the (keyed) permutation Arion and the hash function ArionHash over ${\mathbb{F}}_p$ for odd and particularly large primes. The design of Arion is based on th…
