Implementation of the compression function for selected SHA-3 candidates on FPGA

Implementation of the main building block (compression function) for five different SHA-3 candidates on reconfigurable hardware is presented. The five candidates, namely Blue Midnight Wish, Luffa, Skein, Shabal, and Blake have been considered since they present faster software implementation results compared to the rest of the SHA-3 proposals. The results allow an easy comparison for hardware performance of the candidates.
