ASIC implementations of five SHA-3 finalists

Throughout the NIST SHA-3 competition, in relative order of importance, NIST considered the security, cost, and algorithm and implementation characteristics of a candidate [1]. Within the limited one-year security evaluation period for the five SHA-3 finalists, the cost and performance evaluation may put more weight in the selection of winner. This work contributes to the SHA-3 hardware evaluation by providing timely cost and performance results on the first SHA-3 ASIC in 0.13 μm IBM process using standard cell CMOS technology with measurements of all the five finalists using the latest Round 3 tweaks. This article describes the SHA-3 ASIC design from VLSI architecture implementation to the silicon realization.
