Design of substitution nodes (S-Boxes) of a block cipher intended for preliminary encryption of confidential information
This paper considers a new method for obtaining an S-box, which is one of the nonlinear transformations used in modern block-symmetric cipher systems. This method is based on modular arithmetic, that is, exponentiation modulo polynomial in extended Galois fields [Formula: see text]. The indicators a...
