Synthesis of operations of reverse group matrix cryptographic transformation of information

Svitlana Sysoienko, Olga Melnyk, Mykhailo Pustovit

Abstract

One way to improve existing and build new information security systems is to find and use new functions of cryptographic transformation of information. At present, operations of inverse group matrix cryptographic transformation of information, which can be used to implement cryptographic data coding, are not sufficiently studied. The possibility of synthesizing inverse transformation operations based on the search for inverse group and non-group two-bit operations is investigated. By looking through the transformation data, an algorithm for constructing an inverse group cryptographic transformation was found. Based on the research results, the model of direct and inverse two-operand group cryptographic transformation is formalized. The proposed model provides a simplification of finding the reverse cryptographic transformation, since for its implementation it is necessary to find three inverse two-operand transformations instead of one inverse four-operand transformation

Keywords

cryptographic transformation of information; direct and reverse operation; operation of matrix transformation; group operations; correctness of operation
