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 …

A substitution box (S-box) in data encryption is a non-linear tool that conducts substitution to
assure the overall security of the system. S-box is the most important part of the block cipher …

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 …

Substitution-boxes have significant role in block ciphers as they are the only component
which offers nonlinearity in the anticipated symmetric encryption systems. This paper …

Substitution box is the most significant component of block cipher. The property of
nonlinearity is of great importance for the design of secure substitution boxes. Therefore, it is …

Modern block ciphers deal with the development of security mechanisms to meet the
security needs in several fields of application. The substitution box, which is an important …

Data protection is regarded as one of the biggest issues facing companies that have been
using public data for a long time. Numerous encryption techniques have been used to …

Cryptography entails the practice of designing mathematical algorithms to secure data
communication over insecure networks in the presence of adversaries. In this aspect, a …

A strong substitution-box is main ingredient in cryptography. Many encryption schemes have
been proposed since 1970's such as DES, AES and IDEA. In this paper we construct S …

A substitution box (S-box) is the only non-linear component in many cryptosystems.
Recently, S-box generators have been used intensively in many modern cryptosystems to …
