Abstract
Many kinds of chaotic cryptosystem have been proposed. This proposed technique provides an innovative approach for building secure substitute-boxes cryptographically using rational chaotic mapping. The suggested rational chaotic mapping is effectively capable of mapping the plaintext order to a huge 8 × 8 S-box that meets the bijective function necessities. The usage of rational chaotic map retains the consistency of the S-box design process and was found to be consistent in comparison to other current substitution-box methods which are used to generate S-boxes. The suggested S-box example is retrieved which has been critically analyzed following normal quality parameters involving, strict avalanche criterion, bijection, nonlinearity, linear probability, differential uniformity and bit independence criterion. To figure out its cryptographic high point, the performance results are associated with the recent analyzed S-boxes. The basic examinations support that the suggested S-box development system is significantly creative and powerful to produce cryptographically solid substitute-boxes
