Amandeep Singh . Comparative Analysis of Reduced Round Dynamic AES with Standard AES Algorithm. International Journal of Computer Applications. 183, 10 ( Jun 2021), 41-49. DOI=10.5120/ijca2021921407
Block ciphers are built around the substitution table, or S-Box. The cipher’s protection is improved by better-designed S-Boxes. The Advanced Encryption Algorithm is already a formidable algorithm with excellent linear and differential properties. To provide more security and complexity to standard AES algorithm a dynamic AES with key dependent dynamic S-Boxes developed for each round of dynamic AES. In this study reduced round (RR) variant of dynamic AES with 8 round of encryption is investigated. The aim of this study is to compare the reduced round (RR) variant of dynamic AES with standard AES on the basis of the criterion SAC (strict avalanche criterion) and BIC (bit independence criterion), which further tests the non-linearity and randomness of cipher text on which the security of algorithms is based.
