Skein has the advantages of higher security (resisting against traditional attacks), faster speed and selectable parameters. Therefore, it becomes a strong competitor for next generation Secure Hash Algorithm standard (SHA-3) which will be used widely in communication and security for substitution of SHA-2. The problems of existing works lie in implementation for only one structure and lack detailed comparison of different structures. Based on analysis of the algorithm, the authors accomplished three structures (iterative, 4-unrolled and 8-unrolled) of Skein and ported the designs to FPGA respectively.
