Abstract: Abstract Substitution-boxes are important nonlinear components used for achieving strong confusion as well as cryptographic security in a majority of modern symmetric cryptosystems. Designing cryptographically strong S-boxes has been a major research domain for the designers of symmetric ciphers. In this research work, Firefly algorithm based technique is proposed for designing S-boxes. The proposed Swarm Intelligence (SI) based technique generates cryptographically strong S-boxes. Furthermore, authors analyze strength of the computed S-boxes by testing: nonlinearity, bijectivity, bit-independence criterion (BIC), linear probability and differential uniformity. For the S-box constructed by the proposed technique; average nonlinearity is 109.25 and average strict avalanche criteria (SAC) value is 0.504. The computed performance results for the S-box are compared with some recently reported S-boxes.
