Highly dispersive substitution box (S‐box) design using chaos [PDF]
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 ...

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
