The ASIC implementations achieved a variety of circuits, from compact to very high-speed; throughputs of 3.6G-35.1Gbps with hardware resources of 14.7K-62.8Kgates. The FPGA implementations also showed high performances; throughputs of 1.3G-7.0Gbps with hardware sizes of 750-1,548Slices for Virtex-5, and throughputs of 1.3G-5.5Gbps with hardware sizes of 592-1,535Slices for Spartan-6. In comparison with other SHA-3 candidate Keccak that belongs to a category of a sponge function as same as Luffa, Luffa showed advantages in flexibility from high-speed (comparable to Keccak) to compact (half size of Keccak) hardware implementations. The results also show that data bus structure and parallelism of processing effect in design flexible.
