Substitution boxes are discovered to be significant components of data security in both contemporary and historical ciphers of public-key cryptography. Every online application must be secure. There are two types of S-boxes in the block cipher algorithms: Static S-box: In this type, the same S-box is used in every round of the block cipher. It remains constant throughout the encryption process. Dynamic S-box: Unlike the static S-box, the dynamic S-box employs different S-boxes in each round. The choice of S-box varies based on how it is generated. The dynamic S-box approach enhances security by introducing variability during encryption. The paper you mentioned focuses on dynamic block cipher encryption techniques. It surveys various methods for creating dynamic S-boxes and frames them together as a comprehensive literature review. These techniques play a crucial role in ensuring robust security for data encryption. In modern cryptography, S-box generation and cryptanalysis are crucial. The phases of producing S-Boxes are covered in this article, including bioinformatics technologies, AI techniques, and chaotic systems. The model of a typical S-Box generation system is shown, along with the system’s output. The current work will compare the effectiveness of several approaches to S-box generation for security considerations. The results showed that Bioinformatics gives better results when used in generating the S-Box, and thus Bioinformatics showed higher efficiency in the process of generating and analyzing the S-Box than those other methods.
