ELECTRONIC KEY REGISTRATION METHOD AND ELECTRONIC KEY REGISTRATION SYSTEM
First Claim
1. An electronic key registration method for registering a first electronic key, which is capable of controlling a communication subject, to a controller of the communication subject, the electronic key registration method comprising:
- performing an initial production process includingstoring identification information unique to the communication subject in the controller, andstoring 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 includingwriting 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, andstoring encryption key information related to the encryption key in a database in association with the identification information.

7. An electronic key registration system comprising:
-
a controller located in a communication subject, wherein the controller is configured to store identification information unique to the communication subject; and an electronic key capable of controlling the communication subject, wherein the electronic key is configured to store an encryption key generation code and an encryption key, wherein the controller is configured to write the identification information to the electronic key, obtain the encryption key generation code from the electronic key, calculate the encryption key with an encryption key generation logic that uses the encryption key generation code, and store encryption key information related to the encryption key in a database in association with the identification information.
