SSRN Electronic Journal, 2014 To design a substitution box (S-BOX) using both encryption and decryption. From that, the proposed system can achieve a higher throughput and higher energy efficiency. The S-BOX is designed by using Advanced Encryption Standard (AES). The AES is a symmetric key standard for encryption and decryption of blocks of data.

A Novel Algorithm of Constructing Highly Nonlinear S-p-boxes
Cryptography, 2019 The role of substitution boxes is very important in block ciphers. Substitution boxes are utilized to create confusion in the cryptosystem. However, to create both confusion and diffusion in any cryptosystem p-boxes and chaos base substitution boxes are ...

Boomerang Connectivity Table:A New Cryptanalysis Tool [PDF]
, 2018 A boomerang attack is a cryptanalysis framework that regards a block cipher $E$ as the composition of two sub-ciphers $E_1\circ E_0$ and builds a particular characteristic for $E$ with probability $p^2q^2$ by combining differential characteristics for ...
