CRUSH: A New Cryptographic Hash Function using Iterated Halving Technique

, 2004
. Most of the currently accepted designs for cryptographic hash functions are in the style of a block cipher in feed-forward mode. With increasing interest in all forms of cryptanalysis, this limited choice might become a single point of failure in ...

Optimising the SHA‐512 cryptographic hash function on FPGAs

IET Computers & Digital Techniques, 2014
In this study, novel pipelined architectures, optimised in terms of throughput and throughput/area factors, for the SHA‐512 cryptographic hash function, are proposed. To achieve this, algorithmic‐ and circuit‐level optimisation techniques such as loop unrolling, re‐timing, temporal pre‐computation, resource re‐ordering and pipeline are applied. All the
