In-vehicle device of automatic toll collection system
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】自動料金収受システムの車載機では、通信内容 を暗号化する必要がある。暗号鍵は前記システムの管理 者が管理するが、車載機の設計、製造、配布は別の業者 が行う。保安上の理由から前記システムの運営者以外が 暗号鍵に触れる機会を減らしたい。 【解決手段】暗号鍵を必要とする暗号化装置に、暗号鍵 を含め、暗号鍵を外に出す必要をなくする。 (57) [Summary] [Problem] In an in-vehicle device of an automatic toll collection system, it is necessary to encrypt communication contents. The encryption key is managed by the administrator of the system, but the design, manufacture, and distribution of the vehicle-mounted device are performed by another company. For security reasons, we want to reduce the chances of anyone other than the system operator touching the encryption key. An encryption device that requires an encryption key, including an encryption key, eliminates the need to export the encryption key.
