A TRANSPOSITIONAL ADVANCED ENCRYPTION STANDARD (AES) RESISTS 3-ROUND SQUARE ATTACK

Abstract

In this paper, an advanced encryption standard (AES) variant is proposed that is resistant to linear cryptanalysis, differential cryptanalysis, and the square attack. We replace some procedures in the round function of AES and take the bit as the operation unit to foil the square attack. Also, we apply linear cryptanalysis and differential cryptanalysis to the proposed cipher. The proposed cipher is shown to be superior to AES in many aspects.
