Pitfalls in Designing Substitution Boxes [PDF]
, 2007 Two significant recent advances in cryptanalysis, namely the differential attack put forward by Biham and Shamir [3] and the linear attack by Matsui [7, 8], have had devastating impact on data encryption algorithms. An eminent problem that researchers are facing is to design S-boxes or substitution boxes so that an encryption algorithm that employs the

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 Substitution Box for Lightweight Ciphers to Secure Internet of Things
Journal of King Saud University - Computer and Information Sciences, 2022 The Internet of Things is a resource-constrained device that demands lightweight cryptographic solutions to achieve high performance and optimal security. In lightweight ciphers Substitution Box (S-box) plays an important role as it enables confusion property. However, it is one of the costlier operations.

An Innovative Design of Substitution Box Using Trigonometric Transformation
CoRR, 2023 As the number of hacking events and cyber threats keeps going up, it is getting harder and harder to communicate securely and keep personal information safe on the Internet. Cryptography is a very important way to deal with these problems because it can secure data by changing it from one form to another.
