FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. The method comprises a request step for performing a request in a receiving device, receiving a first random number generated in the receiving device, and storing a count value n generated first from the first random number in a non-volatile storage device; a step for encrypting data intended for transmission based on the count value n; a transmission step which includes the count value n and the encrypted data; and a step for changing the count value stored in the non-volatile storage device each time data are transmitted, where when the changed value exceeds a predefined range, a request is sent to the receiving device, a second random number is received, which is different from the first random number generated in the receiving device, and the count value n'(≠n) initially generated from the second random number is stored in the non-volatile storage device, and the encryption step, transmission step and count value changing step are repeated using the count value n'.
EFFECT: reduced interference between devices when using a remote control panel.
