Title:
Post-quantum hash functions using \mathrm{SL}_n(\mathbb{F}_p)
Authors: Corentin Le Coz, Christopher Battarbee, Ramón Flores, Thomas Koberda, and Delaram Kahrobaei
Abstract:We define new families of Tillich-Zémor hash functions, using higher dimensional special linear groups over finite fields as platforms. The Cayley graphs of these groups combine fast mixing properties and high girth, which together give rise to good preimage and collision resistance of the corresponding hash functions. We justify the claim that the resulting hash functions are post-quantum secure.
