Abstract :
Skein is a hash function that reached the semifinals of the NIST competition for the selection of standard SHA-3. This paper describes the implementation of Skein-512 operating as simple hash function and as MAC function. The design was coded using VHDL language and for the hardware implementation, two XILINX FPGAs, Virtex-6 and Virtex-7 were used. The proposed implementation reaches a data throughput of 894 Mbps at 110 MHz clock frequency for Virtex-6 and a throughput of 975 Mbps at 120 MHz clock frequency for Virtex-7.
