(EN) Electronic-key registration method and electronic-key registration system
(ZH) 电子钥匙登录方法及电子钥匙登录系统
要約
(EN)
This electronic-key registration method, in which a plurality of electronic keys (2) including an initially registered first electronic key and a second electronic key to be registered additionally are registered with a control device (6) for a communication target, is provided with the following steps: an additional-key manufacturing step in which an additional-encryption-key generation code (SC-9) unique to the second electronic key and an additional encryption key (K-9) used in authentication of the second electronic key are stored in the second electronic key; and an additional-key registration step in which, if identifying information (VID-A) unique to the communication target is stored in the second electronic key, the additional-encryption-key generation code is obtained from the second electronic key, an additional encryption key is generated by additional-encryption-key generation logic (g) using the additional-encryption-key generation code and the aforementioned identifying information, and said additional encryption key is stored in the control device.

(ZH)
一种电子钥匙登录方法,将多个电子钥匙(2)登录至通信对象的控制装置(6),该多个电子钥匙包含用于初始登录的第1电子钥匙和用于追加登录的第2电子钥匙,所述电子钥匙登录方法包括如下步骤:追加钥匙制造步骤,将第2电子钥匙所固有的追加密匙生成编码(SC‑9)、和被用于第2电子钥匙的认证的追加密匙(K‑9)存储至第2电子钥匙;以及钥匙追加登录步骤,在通信对象所固有的识别信息(VID‑A)被存储在第2电子钥匙中时,从第2电子钥匙取得追加密匙生成编码,通过使用追加密匙生成编码和识别信息的追加密匙生成逻辑(g)来生成追加密匙,并将追加密匙存储至控制装置。
