Advanced Materials, EarlyView.Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout. A descriptor‐to‐dynamics framework links

A New Method for Designing a 4-bit S-block and Studying Its Results for a Strict Avalanche Criterion
Trudy Universiteta, 2022 The creation of S-boxes and the study of their cryptographic strength is one of the main activities in symmetric cryptography. It is known that one of the most important transformations responsible for the cryptographic strength of a symmetric block encryption algorithm is the S-box replacement table.

Boolean functions satisfying a higher order strict avalanche criterion [PDF]
, 2007 The Strict Avalanche Criterion (SAC) for Boolean functions was introduced by Webster and Tavares in connection with a study of the design of S-boxes. Later Forre extended this notion by defining strict avalanche criteria of order k for Boolean functions of n variables, where 0 ? k ? n - 2; the case k = 0 is the original SAC.

Construction of S-Boxes Using Different Maps Over Elliptic Curves for Image Encryption
IEEE Access, 2021 In this article, we present an encryption technique that can encrypt any digital data. The proposed scheme basically depends on a substitution-permutation network. Two separate bijective maps are used in the proposed algorithm.
