security has become more important than ever. For this purpose, different ciphers using …

The significance of data security has become more critical due to the ever-changing goals
and capabilities of attackers. As a result, many cryptosystems employing diverse …

A substitution box (S-Box) is a crucial component of contemporary cryptosystems that
provide data protection in block ciphers. At the moment, chaotic maps are being created and …

In cryptography, the security of any algorithm relies on the strength of the key used and
nonlinear mapping of the original information or data. It is desirable to have resistance …

The security strengths of block ciphers greatly rely on the confusion components which have
the tendency to transform the data nonlinearly into the perplexed form. This paper proposes …

Secure exchange of sensitive information between different entities is a serious challenge in
today's environment. Therefore, various cryptosystems have been created specifically for …

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 …

The Advanced Encryption Standard (AES) is widely used in different kinds of security
applications. The substitution box (S-box) is the main component of many modern symmetric …

Cryptography deals with designing practical mathematical algorithms having the two
primitive elements of confusion and diffusion. The security of encrypted data is highly …

Block ciphers are widely used for securing data and are known for their resistance to various
types of attacks. The strength of a block cipher against these attacks often depends on the S …
