FIELD: computer technology.
SUBSTANCE: invention relates to computer technology and is intended for encrypting data on data carriers. The expected result is achieved due to the fact that encryption is carried out by the “Grasshopper” block encryption algorithm using keys generated by the “Magma” block encryption algorithm based on the logical address of the encrypted sector and the source encryption key of the device. The address is used as a sector identifier, therefore it is known and does not require storage on a storage medium.
EFFECT: simplifying data encryption while maintaining the reliability of their protection.
