Abstract

In 2007, NIST published a call forparticipationin a contest for a new standardized hash function, the future SHA-3. The call targets software oriented designs and suggests optimization for high-performance platforms. However, NIST explicitly encourages the evaluation of the candidates on 8-bit platforms. In this paper we present an implementation of several SHA-3 candidates, namely BLAKE, Blue Midnight Wish, Grøstl, and SHAvite-3 on an 8-bit microcontroller platform. While BMW shows the highest throughput, BLAKE seems to be the best balanced solution for 8-bit platforms.
