Abstract

In this paper, we present the parity prediction approach of the S-Box for designing high performance and fault detection structures of the AES. Unlike the traditional scheme which is based on using look-up tables, we use the logical gates implementation based on the composite fields for fault detection of S-Box in AES. We find closed formulations for the output parity bits of S-Box considering the composite-field transformation matrix and its inverse in GF(28) as well as the affine transformation. To the best of our knowledge, no closed formulations for parity prediction of the S-Box have been proposed in the open literature.
