摘要：Data security is a major issue because of rapid evolution of data communication over unsecured internetwork. Here the proposed system is concerned with the problem of randomly generated S-box. The generation of S-box depends on Pseudo-RandomNumber-Generators and shared-secret-key. The process of Pseudo-Random-Number-Generator depends on large prime numbers. All Pseudo-RandomNumbers are scrambled according to shared-secretkey. After scrambling,the S-box is generated. In this research,large prime numbers are the inputs to the Pseudo-Random-Number-Generator. The proposed Sbox will reduce the complexity of S-box generation. Based on S-box parameters,it experimentally investigates the quality and robustness of the proposed algorithm which was tested. It yields better results with the S-box parameters like Hamming Distance, Balanced Output and Avalanche Effect and can be embedded to popular cryptography algorithms.
