Abstract: The study is devoted to improving the cryptographic protection of confidential information in the management of forces and means of civil protection, based on the use of advanced matrix cryptographic transformation operations. A new group of cryptographic transformation operations has been identified, which will improve the quality of information protection systems of SES of Ukraine. A method for the synthesis of elementary functions of extended matrix transformation by introducing logical constraint conditions that provide nonlinearity of transformation is developed, which made it possible to obtain a complete set of operations of extended matrix transformation. Methods for the synthesis of cryptographic information transformation operations based on extended matrix transformation have been developed. The algorithm of formation of sequence of pseudo-random numbers on the basis of the expanded matrix cryptographic transformation and the algorithm of formation of sequence which combines matrix and extended matrix cryptographic transformation is developed.
