For decades, the security and privacy of data are among the major challenges faced by
service providers dealing with public data. To cope with these challenges, most of the …

In this article, we present an encryption technique that can encrypt any digital data. The
proposed scheme basically depends on a substitution-permutation network. Two separate …

Protection of data transmitted over the network from illegal access is one of the major
challenges being posed by exponential growth of data in online digital communication …

The S-box is used in various block ciphers and the complexity of encryption essentially
depends on the strength of S-box. The strength of an S-box can be measured by analyzing …

The S-box is utilized within different block ciphers and the complexity of encryption basically
relies on the quality of S-box. The quality of S-box could be measured by breaking down its …

A construction method of S-boxes is given in []. These S-boxes are generated by the
action of symmetric group on AES S-box and these are in number. In this paper, we …

Key-dependent dynamic substitution boxes (S-boxes) are important building blocks of many
image encryption schemes, in which a session key controls the construction of dynamic S …

The substitution box (S-box) plays a vital role in creating confusion during the encryption
process of digital data. The quality of encryption schemes depends upon the S-box. There …

New era ciphers employ substitution boxes (S-boxes) which assist in the provision of
security for the plaintext in the encryption phase and transforming the ciphertext on the …

A novel and efficient image encryption algorithm based on the chaotic system and S-boxes
is introduced in this paper, in which an original S-box is produced by linear fractional …
