Unfolding Method for Shabal on Virtex-5 FPGAs: Concrete Results.pdf

Julien Francq and Céline Thuillet

Abstract

Recent cryptanalysis on SHA-1 family has led the NIST to call for a public competition named SHA-3 Contest. Efficient implementations on various platforms are a criterion for ranking performance of all the candidates in this competition. It appears that most of the hardware architectures proposed for SHA-3 candidates are basic. In this paper, we focus on an optimized implementation of the Shabal candidate. We improve the state-of-the-art using the unfolding method. This transformation leads to unroll a part of the Shabal core. More precisely, our design can produce a throughput over 3 Gbps on Virtex-5 FPGAs, with a reasonable area usage.
