Secured Encryption Technique in S-Box Using Fermat Encoding

In today’s cyber world security has become a major concern over a transmission network. In this article an encryption scheme is proposed using AES method to convert a symmetric key to asymmetric key by encrypting a S-Box. To enhance the level of encryption Fermat encoding is used. Thus cryptographic security hinges on the robustness of these S-Boxes, which contribute to the strength of the encryption algorithms. The study systematically examines the characteristics, security attributes, and applications of S-Boxes thereby providing insights into their roles and effectiveness in safeguarding the sensitive information. Hence findings herein contribute to informed decision-making in selecting the appropriate type of S-Boxes based on specific security requirements, paving the way for enhanced cryptographic design and implementation.
