A New Improved AES S-box With Enhanced Properties

Abderrahmane Nitaj and Willy Susilo and Joseph Tonien

Abstract: The Advanced Encryption Standard (AES) is the most widely used symmetric encryption algorithm. Its security is mainly based on the structure of the S-box. In this paper, we present a new way to create S-boxes for AES and exhibit an S-box with improved cryptographic properties such as Bit Independence Criterion (BIC), periodicity, algebraic complexity, Strict Avalanche Criterion (SAC) and Distance to SAC.
