FIELD: data protection.
SUBSTANCE: invention relates to cryptographic protection of data, namely to asymmetric encryption methods, and can be used in message protection devices in the form of separate digital packages, tuples of equal length from unauthorized access in open networks, circuits, data transmission channels. Method involves encrypting a message using a modified backpack task, in which each public key is used to encrypt not one bit of the original message but a group of bits. Thus, it is allowed to use repeating elements of backpack vector, which makes it difficult to attempt to select initial parameters.
EFFECT: technical result consists in improvement of cryptographic resistance before transmitting a message over open communication channels.
