 Core i5, Fugue-256 runs at 14 cycles/byte.Fugue's design starts from the hash function Grindahl, and like Grindahl uses the S-box from AES, but it replaces the 4×4 column mixing matrix with a 16×16 "super-mix" operation which greatly improves diffusion.The "super-mix" operation is, however, only slightly more computationally expensive to implement than the AES mixing strategy.
