Substitution boxes are very important for cryptographic structures. But getting an 8-bit strong
s-box is a difficult problem. To address this problem, a new approach is proposed in this …

There are two basic requirements for symmetric encryption algorithms. The first of these is
diffusion. The second and most important is confusion. In these algorithms, this requirement …

In symmetric cryptography, a cryptographically secure Substitution-Box (S-Box) is a key
component of a block cipher. S-Box adds a confusion layer in block ciphers that provide …

The Substitution box (S-box) is pivotal in block cipher cryptosystems, as it provides critical
properties of non-linearity and confusion essential for robust security. Despite the …

Cryptography aims to design algorithms for the protection of important data transmitted over
unsecured networks. These algorithms encrypt the data and render it incomprehensible …

S-boxes are very important structures for encryption algorithms. For S-boxes to be strong,
they should not be as linear as possible. Obtaining an S-box with high nonlinearity is a …

The secure computation of symmetric encryption schemes using Yao's garbled circuits, such
as AES, allows two parties, where one holds a plaintext block m and the other holds a key k …

Yer değiştirme kutusu (s-box), kriptografik yapılar için hayati öneme sahiptir. Çünkü bir
simetrik şifreleme algoritmasında karıştırma olarak adlandırdığımız gereksinimi yerine …

Криптографічний S-блок є найважливішим компонентом сучасних шифрів, від якості
якого у великій мірі залежить ефективність, криптографічна захищеність та швидкодія …
