Randamization Technique for Desiging of Substitution Box in Data Encryption Standard Algorithm

By Nilima S. Alind Nitin Aror

DOI: https://doi.org/10.5815/ijmsc.2019.03.03, Pub. Date: 8 Jul. 2019

A new approach for the generation of randomized substitution box (S-box) based on the concept of a redesign of S-box with fewer numbers of input bits processed at a time as compared to existing S-box in Data Encryption Standard (DES) Algorithm. The results of experimentation prove that proposed randomized approach also generate promising results, which can be particularly useful for devices with less processing power. Proposed approach retains the diffusion and confusion property of a good cryptosystem algorithm.
