An Improved S-Box Generation Method using Metaheuristic Optimization Technique

Shubhankar Vashishta , Lakshay Srivastava , Dr. C. Jothi Kumar

Substitution boxes (S-boxes) are a crucial nonlinear component in modern block and stream ciphers' cryptanalytic resistance. Due to their relevance, there is a wide range of S-box construction techniques. The success of AES (Advanced Encryption Standard) posed cryptographers with new challenges in creating powerful substitution-boxes using various underlying approaches. There are various parameters that play a vital role in creating a robust S-Box that is secure enough to use which includes Nonlinearity, differential uniformity, absolute indicator value of global avalanche characteristics, Bits Independence Criterion (BIC), confusion characteristics, transparency order etc. We can obtain the desired value for a parameter by using various optimization techniques like PSO, GSA etc. In the proposed scheme, metaheuristic optimization technique will be used for setting the values of the above-mentioned parameters.
