FPGA implementation of new standard hash function Keccak
Tatsuya Honda, Hendra Guntur, Akashi Satoh · 2014
High-speed hardware for Keccak, which was selected as a new standard hash function named SHA-3, was developed and its performance was evaluated against SHA-1 and -2 circuits through the use of various FPGA platforms. The results showed that Keccak is suitable for high-speed hardware implementations, but it is getting harder to implement on new FPGA devices, due to the current trends in architecture for state-of-the-art FPGAs. We also clarify the drawbacks of Keccak due to its structure.
