An efficient construction of key-dependent substitution box based on chaotic sine map
International Journal of Distributed Sensor Networks, 2019 A substitution box is a core component of the popular symmetric-key algorithms. However, the major problem of the conventional substitution boxes is the statistic behavior, which is employed as a fixed-size lookup table.
