Highly dispersive substitution box (S‐box) design using chaos
ETRI Journal, 2020 Highly dispersive S‐boxes are desirable in cryptosystems as nonlinear confusion sub‐layers for resisting modern attacks. For a near optimal cryptosystem resistant to modern cryptanalysis, a highly nonlinear and low differential probability (DP) value is ...

A Very Compact S-Box for AES [PDF]
, 2005 A key step in the Advanced Encryption Standard (AES) algorithm is the “S-box.” Many implementations of AES have been proposed, for various goals, that effect the S-box in various ways. In particular, the most compact implementations to date of Satoh et al.[14] and Mentens et al.[6] perform the 8-bit Galois field inversion of the S-box using subfields ...

Mathematics, 2023 A Substitution box (S-box) is an important component used in symmetric key cryptosystems to satisfy Shannon’s property on confusion. As the only nonlinear operation, the S-box must be cryptographically strong to thwart any cryptanalysis tools on ...

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2021 The purpose of this article is to construct an internal function underlying the “Sponge” scheme for constructing cryptographic hash functions. An internal function in the “Sponge” scheme is a fixed-length transformation or permutation that

Reconfigurable Research and Circuit Design of Two Types of Nonlinear Cryptographic Components [PDF]
Jisuanji gongcheng, 2022 During the implementation of a cryptographic processor, considerable resources are wasted because of the isomerization of the S box and the Non-linear Boolean Function(NBF) in its symmetric cipher.A reconfigurable circuit structure of an AES-like S box ...

Scientific Journal of Informatics, 2020 An irreducible polynomial is one of the main components in building an S-box with an algebraic technique approach. The selection of the precise irreducible polynomial will determine the quality of the S-box produced. One method for determining good S-box

On the Design of S-Boxes [PDF]
, 2007 The ideas of completeness and the avalanche effect were first introduced by Kam and Davida [1] and Feistel [2], respectively. If a cryptographic transformation is complete, then each ciphertext bit must depend on all of the plaintext bits. Thus, if it were possible to find the simplest Boolean expression for each ciphertext bit in terms of the ...
