FIELD: physics.
SUBSTANCE: invention relates to the field of digital information transmission. System for cryptographic processing includes message unit (1, 7, 12) for provision of first presentation of message (3, 6, 11), where first presentation of message is presentation of message, key unit (2) for providing key (4, 9, 14) representation, where the key representation is an encrypted representation of the first key of the first cryptographic algorithm and the second key of the second cryptographic algorithm, where the first cryptographic algorithm differs from the second cryptographic algorithm, stages block (5, 10, 15) for performing the step of the first cryptographic algorithm and the step of the second cryptographic algorithm based on the first presentation of message (3, 6, 11) and presenting the key to obtain a second representation of message (6, 11, 16).
EFFECT: technical result consists in improvement of reliability of data encryption due to simultaneous execution of two cryptographic algorithms.
