ABSTRACT Allowing good performances on different platforms is an important criteria for the selection of the future sha-3 standard. In this paper, we consider the compact implementations of blake, Grøstl, jh, Keccak and Skein on recent fpga devices. Our results bring an interesting complement to existing analyzes, as most previous works on fpga implementations of the sha-3 candidates were optimized for high throughput applications. Following recent guidelines for the fair comparison of hardware architectures, we put forward clear trends for the selection of the future standard. First, compact fpga implementations of Keccak are less efficient than their high throughput counterparts. Second, Grøstl shows interesting performances in this setting, in particular in terms of throughput over area ratio. Third, the remaining candidates are comparably suitable for compact fpga implementations, with some slight contrasts (in area cost and throughput).

    ABSTRACT: This contribution describes our efforts in the design of a 130 nm CMOS ASIC that implements Skein, BLAKE, JH, Grøstl, and Keccak, the five candidates selected by NIST in the third round SHA-3 competition. The objective of the ASIC is to accurately measure the performance and power dissipation of each candidate when implemented as an ASIC. The design of this ASIC, and its optimization for benchmarking, creates unique problems, related to the integration of five heterogeneous architectures on a single chip. We implemented each algorithm in a separate clock region, and we integrated an on-chip clock generator with flexible testing modes. The chip is further designed to be compatible with SASEBO-R board, a power-analysis and side-channel analysis environment. We report the design flow and test results of the chip, including area, performance and shmoo plot. Furthermore, we compare our ASIC benchmark with an equivalent FPGA benchmark.

    ABSTRACT: Cryptographic hash functions are at the heart of many information security applications like digital signatures, message authentication codes (MACs), and other forms of authentication. In consequence of recent innovations in cryptanalysis of commonly used hash algorithms, NIST USA announced a publicly open competition for selection of new standard Secure Hash Algorithm called SHA-3. An essential part of this contest is hardware performance evaluation of the candidates. In this work we present efficient hardware implementations and hardware performance evaluations of SHA-3 finalists. We implemented and investigated the performance of SHA-3 finalists on latest Xilinx FPGAs. We show our results in the form of chip area consumption, throughput and throughput per area on most recently released devices from Xilinx on which implementations have not been reported yet. We have achieved substantial improvements in implementation results from all of the previously reported work. This work serves as performance investigation of SHA-3 finalists on most up-to-date FPGAs.
