Cryptanalysis of TS-Hash

Aleksei Udovenko

Abstract

This note presents attacks on the lightweight hash function TS-Hash proposed by Tsaban, including a polynomial-time preimage attack for short messages (at most n/2 bits), high-probability differentials, a general subexponential-time preimage attack, and linearization techniques.
