Abstract: This technical solution relates to the field of digital data processing, in particular to the methods of managing backups of computer devices. The technical result is an increase in the security of backups due to using symmetric cryptographic keys transmitted over a quantum channel, each of which corresponds to a specific backup.

Abstract: The present technical solution refers to the area of arrangement of network data exchange schemes among a plurality of devices, particularly, for data exchange among devices of the Internet of things (IoT). The technical result is the increase of protection of the information exchange of data among devices by the method of arrangement of the trusted interaction environment and provision of each participant of the information exchange in the trusted environment with the protected security module in the environment of which all necessary operations are performed for implementation of data exchange with the use of a set of symmetrical access keys. The claimed solution is implemented by means of ensuring the trusted environment of data packets exchange among IoT devices in which each of IoT devices is equipped with the security module containing symmetrical sets of keys used for encryption, signing and check of the transmitted data packets.
