(ZH) 访问限制装置、车载通信系统及通信限制方法
要約
(EN)
Provided are an access limiting device, an on-board communication system, and a communication limiting method that can prevent leakage of information and the like to the outside by an unauthorized access to an in-vehicle network by an unauthorized program. Communications between an in-vehicle network of a vehicle and an external device, such as a terminal device (3), are performed via a security controller (10). The security controller (10) is capable of adding or updating a program involving information transmission or reception process. The security controller (10) performs a process of limiting access to in-vehicle network information generated as a result of execution of a program on the basis of an access right level of each program and an access permission level of each item of information. The security controller (10), when transmitting information to the in-vehicle network during execution of a program, limits the transmission on the basis of the access right level of each program and the access permission level of each information item.

(ZH)
提供一种能够防止由于非法程序向车辆网络的非法访问而产生信息向外部泄漏等的访问限制装置、车载通信系统及通信限制方法。经由安全控制器(10)进行车辆的车内网络和终端装置(3)等外部装置之间的通信。安全控制器(10)能够追加或更新伴随着信息的收发处理的程序。安全控制器(10)进行基于各程序的访问权限等级及各信息的访问许可等级对伴随着程序的执行而产生的向车内网络的信息的访问进行限制的处理。另外,安全控制器(10)在伴随着程序的执行向车内网络发送信息的情况下,基于各程序的访问权限等级及各信息的访问许可等级限制发送。
