High performance and area efficient Secure Hash Algorithm (SHA-3) hardware realization is investigated and proposed in this work. In addition to the new and simplified round constant (RC) generator, the presented SHA-3 hash implementations employed architectural optimization approaches based on the concepts of unrolling, pipelining and subpipelining. This has therefore produced a total of five implementations of SHA-3 which are denoted as Cases I-V in both FPGA and ASIC. Considering the trade-offs between the performance and hardware cost, the best architecture in term of the throughput and area efficiency is identified in Case V. The architecture has the highest throughput of 16.51 Gbps and area efficiency of 11.47 Mbps/slices for the FPGA implementation. While in ASIC, our best implementation (Case V) achieves the highest throughput of 48 Gbps.
