### Abstract

We present a practical cryptographic hash

function based on the Miyaguchi–Preneel construction,

which instead of using a block cipher as the main component

uses a modular matrix multiplication. Thus as the core

component it uses a compression function which is closely

related to the theoretical lattice based hash function considered

by Goldreich, Goldwasser and Halevi. We show that by

suitable parameter choices we can produce a hash function

which is comparable in performance to existing deployed

hash functions such as SHA-1 and SHA-2.
