Abstract. The substitution box (S-box) of the Advanced Encryption Standard (AES) is based on the multiplicative inversion s(x) = x-1 in GF(256) and followed by an affine transforma...
A key step in the Advanced Encryption Standard (AES) algorithm is the “S-box.” Many implementations of AES have been proposed, for various goals, that effect the S-box in vari...
Abstract— A hardware algorithm for integer division is proposed. It is based on the digit-recurrence, non-restoring division algorithm. Fast computation is achieved by the use of...
We present a dynamic bit-width adaptation scheme in DCT applications for efficient trade-off between image quality and computation energy. Based on sensitivity differences of 64 ...
