dc.description.abstractNowadays, data security and privacy have become a major challenge. To secure the information, most of the organizations use data encryption and decryption methods known as ciphers. Modern day ciphers use key-dependent dynamic substitution boxes (S-Boxes) to encrypt and decrypt data. An S-Box is generated from the key to make it dynamic. In this thesis, a novel method of S-Box design is presented. To prove the strength of the proposed S-Box, a critical evaluation is done with standard properties that include Bit Independence Criterion, Nonlinearity, Linear Probability, Differential Uniformity, and Strict Avalanche Criterion. The results are compared with other well-known S-Boxes. The results of the proposed S-Box are quite encouraging and hence can be used in future ciphers.
