Differentially 4 4-uniform permutations on F _ 2^ 2k F 2 2 k with high nonlinearity are chosen
as Substitution boxes in many block ciphers and some stream ciphers. Recently, Qu et …

Many block ciphers use permutations defined on F (2 2k) with low differential uniformity, high
nonlinearity, and high algebraic degree as their S-boxes to provide confusion. It is well …

Permutations over 𝔽 2 2 k F_2^2k with low differential uniformity, high algebraic degree and
high nonlinearity are of great cryptographic importance since they can be chosen as the …

Constructing S-boxes with low differential uniformity and high nonlinearity is of cardinal
significance in cryptography. In the present paper, we show that numerous differentially 4 …

Substitution boxes (S-boxes) are important components of block ciphers that can cause
confusion in cryptosystems. The functions used as S-boxes should have low differential …

Block ciphers use Substitution boxes (S-boxes) to create confusion into the cryptosystems.
For resisting the known attacks on these cryptosystems, the following criteria for functions …

Block ciphers use substitution boxes (S-boxes) whose aim is to create confusion into the
cryptosystems. Functions used as S-boxes should have low differential uniformity, high …

Many block ciphers use permutations defined over the finite field $\mathbb {F} _ {2^{2k}} $
with low differential uniformity, high nonlinearity, and high algebraic degree to provide …

Differentially 4-uniform permutations over \mathbbF_2^2k, especially those with high
nonlinearity and high algebraic degree, are cryptographically significant mappings as they …

In this paper, we further study the switching constructions of differentially 4-uniform
permutations over F 2 2 k from the inverse function and propose several new explicit …
