The expansion of worldwide networking has created new possibilities for management,
development, and presentation in the form of digital data. The uncomplicated accessibility to …

In modern-day block ciphers, the role of substitution-boxes is to transform the plaintext data
nonlinearly to generate ciphertext data with sufficient confusion. It has been well-confirmed …

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 …

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 …

Secure exchange of sensitive information between different entities is a serious challenge in
today's environment. Therefore, various cryptosystems have been created specifically for …

In today's digital society, new design alternatives are needed for substitution box structures,
which has critical importance in developing secure information systems that are resistant to …

Several dynamic substitution box (S-box) generators have been proposed in recent years.
Some of the existing S-box generators can generate an S-box with good cryptographic …

In the modern block cipher, the substitution box (S-box) is a nonlinear constituent that plays
a substantial role to create the confusion in ciphertext. S-boxes with low value of differential …

In consideration of the reduced chaotic range and susceptibility of a single chaotic map, we
exploit the 4D-hyperchaotic system for creating three S-boxes ie, red, green and blue S …

Symmetric encryption is appraised as one of the key ways in which end-to-end data transfer
security is guaranteed. To inject confusion in the substitution phase of the modern block …
