Official abstract text for this publication.
A method for registering a first electronic key, which is capable of controlling a communication subject, to a controller of the communication subject, the method including: performing an initial production process including storing identification information unique to the communication subject in the controller, and storing an encryption key generation code unique to the first electronic key and an encryption key that is used to verify the first electronic key in the first electronic key; and performing an initial registration process including writing the identification information stored in the controller to the first electronic key, obtaining the encryption key generation code from the first electronic key, generating the encryption key with an encryption key generation logic that uses the encryption key generation code, storing the encryption key in the controller, and storing encryption key information related to the encryption key in a database in association with the identification information.
