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 …

With the exponential increase in communication sector, the risk of information management
also increases. Although there is enormous input from the cybersecurity perspective, still a …

Substitution-boxes (S-Boxes) are important non-linear components in block cryptosystem,
which play an important role in the security of cryptosystems. Constructing S-Boxes with a …

As the motivations and capabilities of threat actors continue to evolve, providing data
security has become more important than ever. For this purpose, different ciphers using …

Substitution-boxes, or simply S-boxes, are used to increase confidentiality in the substitution
stage of most cryptosystem approaches. In this paper, an efficient method for the …
