Abstract:
PROBLEM TO BE SOLVED: To prevent a situation in which an operation device incorrectly operates other operation target devices than an operation target device, in an environment of the operation device communicable with a plurality of operation target devices through a wireless LAN.SOLUTION: In a pairing step S100, an operation target device SK verifies coincidence between an authentication random number displayed on a display device and a random number input to an operation device SP, and if both are coincident, a public key of the operation target device SK is transferred to the operation device SP. In an activation step S200, the operation device SP requesting the operation target device SK to activate verifies whether a genuine public key of the operation target device SK is held. If the genuine public key is held, a session key is shared between the operation device SP and the operation target device SK. In a secure communication step S300, communication between the devices is performed using the session key.
