Chaotic systems are widely used in image encryption due to their sensitivity to initial values,
ergodicity, and other properties; many image encryption algorithms based on chaotic …

In this communication, we present a technique to synthesize resilient nonlinear mechanisms
for the construction of substitution box. The proposed nonlinear component assists in …

Block ciphers encrypt blocks of plaintext, messages, into blocks of ciphertext under the
action of a secret key, and the process of encryption is reversed by decryption which uses …

Substitution box (S-box) is one of the most important components in the design of block
ciphers. In this work, different from traditional methods, we convert the construction of n× n S …

A method for obtaining cryptographically strong 8× 8 S-boxes based on chaotic maps is
presented and the cryptographical properties such as bijection, nonlinearity, strict avalanche …

In this work, we present a simple algorithm to design n× n‐bits substitution boxes (S‐boxes)
based on chaotic time series of the logistic map for different carrying capacities. The use of …

The substitution box (S-box) is an important component in block encryption algorithms. In
this Letter, the problem of constructing S-box is transformed to a Traveling Salesman …

In numerous encryption frameworks, the first information is changed into encoded form by
applying nonlinear substitutions and affecting diffusion. The goal of the nonlinear change is …

With the exponential growth in Internet-of-Things (IoT) devices, security and privacy issues
have emerged as critical challenges that can potentially compromise their successful …

Tang et al. proposed a novel method for obtaining S-boxes based on the well-known two-
dimensional chaotic Baker map. Unfortunately, some mistakes exist in their paper. The faults …
