DEVICE FOR DATA ENCRYPTION ITERATION OF THE “MAGMA” ALGORITHM ACCORDING TO GOST R 34.12-2015 STANDARD Russian patent published in 2022 - IPC H04L9/06 G09C1/00 

FIELD: cryptography.

SUBSTANCE: invention relates to means of cryptographic protection of information, namely to data encryption devices in accordance with the “Magma” algorithm according to GOST R 34.12-2015 standard, and can be used in trusted sensor systems for collecting, processing and transmitting digital data. The result is achieved by the fact that inverted calculations are implemented in the cryptographic information protection device for operations that make up the iteration of the cryptographic transformation. In this case, isomorphism is preserved between the transformations in the direct and inverted representation, while the correspondence of the input data in the direct and inverted representation, the correspondence of the output data and intermediate results in the direct and inverted representation is retained.

EFFECT: providing cryptographic data processing in accordance with the iteration of the “Magma” algorithm according to GOST R 34.12-2015 standard with their inverted representation.
