A design of multiple color image encryption scheme based on finite algebraic structures [PDF]
Scientific ReportsThis article introduces an innovative method for constructing substitution and permutation boxes and their application in image encryption. In encryption, the essential component that creates confusion is the substitution box(S-box).

A secure key dependent dynamic substitution method for symmetric cryptosystems [PDF]
PeerJ Computer Science, 2021 The biggest challenge for symmetric cryptosystems is to replace their static substitution with dynamic substitution, because static substitution S-boxes make the symmetric block ciphers more vulnerable to attacks.

A method for generation of substitution box based on random selection
Egyptian Informatics Journal, 2022 Two basic requirements must be met to encrypt data. These requirements are confusion and diffusion properties. In particular, block cipher algorithms are based on a cryptographic component known as substitution-box to provide the need for confusion ...

Pareto-optimal hardware for substitution boxes [PDF]
International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 2005 En este trabajo, proponemos una metodología basada en la programación genética para generar automáticamente diseños de hardware de cajas de sustitución necesarias para muchos criptosistemas como el sistema de cifrado DES. Nuestro objetivo es desarrollar especificaciones de hardware mínimas, que minimicen tanto el espacio (es decir, el número de puerta ...

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

Mom-and-Pop Meet Big Box: Complements or Substitutes? [PDF]
SSRN Electronic Journal, 2009 Abstract In part due to the popular perception that Big-Boxes displace smaller, often family owned (a.k.a. Mom-and-Pop) retail establishments, several empirical studies have examined the evidence on how Big-Boxes’ impact local retail employment but no clear consensus has emerged.

IEEE Access, 2021 The cryptanalytic resistance of modern block and stream encryption systems mainly depends on the substitution box (S-box). In this context, the problem is thus to create an S-box with higher value of nonlinearity because this property can provide some ...
