A Novel Cryptographic Substitution Box Design Using Gaussian Distribution [PDF]
IEEE Access, 2019 In this paper, a novel method is being proposed to construct a substitution box or Boolean function for block ciphers using Gaussian distribution and linear fractional transform. The substitution box is constructed by employing a linear fractional transform based on Box-Muller transform, polarization decision, and central limit algorithm.

Side-Channel Analysis of Chaos-Based Substitution Box Structures [PDF]
IEEE Access, 2019 There is a theoretically strong relationship between chaos and cryptology. In practice, one of the most successful applications of this relationship is chaos-based s-box structures. However, the performance metrics of chaos-based s-box designs are worse compared to those for s-box structure based on algebraic techniques used in modern encryption ...

A method for generation of substitution box based on random selection
Egyptian Informatics Journal, 2022 Two basic requirements must be met to encrypt data. These requirements are confusion and diffusion properties. In particular, block cipher algorithms are based on a cryptographic component known as substitution-box to provide the need for confusion ...

A secure key dependent dynamic substitution method for symmetric cryptosystems [PDF]
PeerJ Computer Science, 2021 The biggest challenge for symmetric cryptosystems is to replace their static substitution with dynamic substitution, because static substitution S-boxes make the symmetric block ciphers more vulnerable to attacks.
