Substitution Box (S-Box): Current Design Techniques and Future Challen
University of Wah Journal of Computer Science, 2018S-box is considered a vital component of modern encryption algorithm. The secure substitu tions in the form of S-box define the security of encryption algorithm. The substitutions are defined on the basis of set of cryptographic properties. A good S-box requires having good bounds of cryptographic properties.

Implementation White Box Cryptography in Substitution-Permutation network
2020 9th Mediterranean Conference on Embedded Computing (MECO), 2020Advances in technology have led not only to increased security and privacy but also to new channels of information leakage. New leak channels have resulted in the emergence of increased relevance of various types of attacks. One such attacks are Side-Channel Attacks, i.e. attacks aimed to find vulnerabilities in the practical component of the algorithm.

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.

A Substitute for the Water Box in the Original EMI Brain Scanner
Journal of Computer Assisted Tomography, 1977A modified water box for the EMI brain scanner is described. The modified box permits parts of the body other than the brain to be scanned. The patient setup for brain scans is simplified, and motion artifacts have almost disappeared.

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.

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.

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.

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.
