Hardware implementation of one class of 8-bit permutations

The paper studies the issues of implementation of one class of S-Boxes on FPGA and ASIC and compares them with the implementation of arbitrary mappings $V_8 \to V_8$. The way of implementation of arbitrary S-Box is studied. It's shown that any S-Box over $V_8$ can be implemented using 40 LUTs (812 GE). For one class of S-Boxes over $V_8$ with high cryptographic properties, the possibility of their implementation using 19 LUTs (147 GE) is shown.
