Abstract: A key management server (200) uses a manufacturer ID and generates a manufacturer key. An equipment management device (300) stores the manufacturer key and using the manufacturer key and an equipment ID generates an equipment authentication key. Production equipment (110) stores the manufacturer ID the equipment ID and the equipment authentication key. A communication terminal (400) acquires the manufacturer ID the equipment ID and authentication data from the production equipment (110). The communication terminal (400) transmits the manufacturer ID and the equipment ID to the key management server (200); the key management server (200) using the manufacturer ID and the equipment ID generates an equipment authentication key; and the communication terminal (400) acquires the equipment authentication key from the key management server (200). The communication terminal (400) then uses the equipment authentication key to verify the authentication data.
