摘要: An immobilizer ECU transmits a vehicle ID code and a SEED code, which is read from an electronic key, to a data center online. The data center generates an encryption key from the received SEED code and a first logic, and generates a further SEED code from the encryption key, the vehicle ID code, and a second logic. The immobilizer ECU obtains the further SEED code online from the data center, generates the encryption key from the obtained further SEED code, the vehicle ID code, and the second logic, and stores the encryption key.

摘要: An offline immobilizer ECU reads an encryption key generation code from an offline additional electronic key and generates an electronic key encryption key for the offline additional electronic key using the encryption key generation code and a communication subject key encryption key held by the immobilizer ECU. The immobilizer ECU stores, in a memory, the generated electronic key encryption key and a key ID code that is read from the offline additional electronic key.

摘要: An electronic key registration system includes a controller of a communication subject, an initial electronic key that communicates with the communication subject and has an initial encryption key generation code, an additional electronic key that communicates with the communication subject, and an information center including an additional encryption key. The initial electronic key holds an initial encryption key generated from the initial encryption key generation code and a logic. The controller holds the logic and identification information of the communication subject. The controller acquires the initial encryption key generation code from the initial electronic key, generates an initial encryption key from the initial encryption key generation code and the logic held by the controller, and stores the initial encryption key. The information center sends the additional encryption key to the additional electronic key or the controller through a network.
