ABC Optimization Based Construction of Strong Substitution-Boxes
Wireless Personal Communications, 2018Most of the block ciphers contain substitution-boxes as their cornerstone primitive to add requisite nonlinearity. S-boxes are responsible to ensure strong confusion and resistance to linear and differential assaults. The security of such ciphers relies on the strength of S-boxes deployed during substitution stage.

A Novel Algebraic Technique for the Construction of Strong Substitution Box
Wireless Personal Communications, 2017The ability of substitution box (S-box) to create confusion in the cipher attracted different authors to design strong cryptographic S-box. The S-box can further be used in different cryptosystems to create confusion. In this article, a novel scheme is introduced to develop S-box with strong arithmetic background.

An efficient construction of substitution box with fractional chaotic system
Signal, Image and Video Processing, 2013In this article, we have presented an innovative formation of nonlinear element of block cipher. The suggested construction is chaos based, where we used fractional Rossler chaotic system. We have studied various features of our proposed nonlinear component.

Relating Differential Distribution Tables to Other Properties of of Substitution Boxes
Designs, Codes and Cryptography, 2000Relationships among various characteristics of an \(n \times m\) S-box \((n > m)\) are investigated. First, in addition to the well-known differential distribution table two other tables, namely auto-correlation distribution table and correlation immunity distribution table associated with an S-box are introduced.

Application of Genetic Algorithms in the Construction of Invertible Substitution Boxes
2016Existing literature shows that genetic algorithms can be successfully used for automated construction of S-boxes. In this paper we show the usage of genetic algorithm, more specifically NSGA-II, as an aid in designing and testing of invertible substitution boxes which are special case of substitution boxes.

Construction of robust substitution boxes based on chaotic systems
Neural Computing and Applications, 2017The construction of substitution boxes (s-boxes) is an important research area in cryptography. S-box is an important mathematical object. The aim of this study is to construct s-box designs with the best performance criteria for all chaotic system classes. The proposed method achieves the best s-box designs for all chaotic systems classes.

A group theoretic approach to construct cryptographically strong substitution boxes
Neural Computing and Applications, 2012In this paper, we present a method to construct a substitution box used in encryption applications. The proposed algorithm for the construction of substitution box relies on the linear fractional transform method. The design methodology is simple, while the confusion-creating ability of the new substitution box is complex.
