The substitution box (S-box) component is the heart of the advanced encryption standard (AES) algorithm. The S-box values are generated from the multiplicative inverse of Galois finite field GF(28) with an affine transform. There are many techniques of gaining the multiplicative inverse values were proposed. Most of the hardware implementations of S-box were using look-up tables (LUTs) (memory-based) to store the values which employ the largest area in design. In this paper, a software method… CONTINUE READING
