The substitution boxes are the only components in most of symmetric encryption systems that induce nonlinearity to provide efficacious data confusion. The cryptographic potency of these systems primarily depends upon the caliber of their S-boxes. This brings new challenges to design cryptographically efficient S-boxes to develop strong encryption systems. Here, a simple and effective method to design an efficient 8×8 S-box is put forward. The proposed design methodology is based on the classical Fisher-Yates shuffle technique. A piece-wise linear chaotic map is incorporated to act as a source to generate random numbers for proficient execution of shuffle technique. The construction of dynamic S-box is under the control of secret key. The performance evaluation of proposed S-box against standard statistical tests like bijective property, nonlinearity, strict avalanche criteria and equiprobable I/O XOR distribution reveals its excellent performance. Moreover, the proposed S-box is also compared with some recent chaos-based S-boxes. The investigations confirm that the design is consistent and suitable for secure communication. © Springer-Verlag Berlin Heidelberg 2014.
