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.

A novel systematic byte substitution method to design strong bijective substitution box (S-box) using piece-wise-linear chaotic map [PDF]
PeerJ Computer Science, 2022 Cryptography deals with designing practical mathematical algorithms having the two primitive elements of confusion and diffusion. The security of encrypted data is highly dependent on these two primitive elements and a key.

Highly dispersive substitution box (S‐box) design using chaos [PDF]
ETRI Journal, 2020 Highly dispersive S‐boxes are desirable in cryptosystems as nonlinear confusion sub‐layers for resisting modern attacks. For a near optimal cryptosystem resistant to modern cryptanalysis, a highly nonlinear and low differential probability (DP) value is ...

A Substitution Box for Lightweight Ciphers to Secure Internet of Things
Journal of King Saud University - Computer and Information Sciences, 2022 The Internet of Things is a resource-constrained device that demands lightweight cryptographic solutions to achieve high performance and optimal security. In lightweight ciphers Substitution Box (S-box) plays an important role as it enables confusion property. However, it is one of the costlier operations.
