摘要：Summary Symmetric encryption has been a standout amongst the most reliable option by which security is accomplished. In modern block symmetric cyphers, the substitution-boxes have been playing a critical role of nonlinear components that drives the actual security of cyphers. In this paper, the travelling salesman problem and piece-wise linear chaotic map are explored to synthesize an efficient configuration of 8×8 substitution-box. The proposed anticipated design has the consistency which is justified by the standard performance indexes. The statistical results manifest that the prospective substitution-box is cryptographically more impressive as compared to some recent investigations.
