FIELD: physics.
SUBSTANCE: invention relates to controlled control of operations performed by multiple devices. Control is carried out by secure transfer of tokens, operations of multiple interconnected devices, each of which has hardware based on the concept of trusted execution environment (TEE), and a controller, wherein each controller owns the tokens assigned by the management server, and the TEE of each device is configured to issue a response to the validation claim through a proof protocol with zero knowledge proof (ZKP) and generation and validation of digital signature of possession of one-time use and its corresponding claim for validation of signature of possession. Tokens can be transferred from one interconnected device to another in the online mode through the server or in the autonomous mode by means of direct communication between the devices.
EFFECT: higher safety and reliability.
