Abstract:
A controlled device generates an authentication random number. A control device accepts input of a random number from an input device. The controlled device verifies if the displayed authentication random number and the random number transferred from the control device are identical to transfer a public key of the controlled device to the control device. The controlled device generates a token. The control device encrypts the token with the public key of the controlled device. The controlled device decrypts the token and verifies if the token transferred from the control device and the generated token are identical to generate a session key. The control device stores the session key into the storage device. The control device controlling the controlled device by encrypted communication using the session key.
