Unfolding Method for Shabal on Virtex-5 FPGAs: Concrete Results.pdf
Julien Francq and CÚline 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.
