This paper proposes a compact design of SMS4 S-box using combinational logic which is suitable for the implementation in area constraint environments like smart cards. The inversion algorithm of the proposed S-box is based on composite field GF(((2 2) 2) 2) using normal basis at all levels. In our approach, we examined all possible normal basis combinations(More)
