智能交通系统

[中文适用范围]： 本文件包含一组 ITS 站点安全服务的规范，这些服务用于确保可信实体之间交换的信息来源的真实性和完整性，即： — 作为有界安全管理实体运行的设备之间，即 ISO 21217 中规定的“ITS 站点通信单元”(ITS-SCU) 和“ITS 站点单元”(ITS-SU)；以及 — ITS-SU（由一个或多个 ITS-SCU 组成）与外部可信实体（如传感器和控制网络）之间。这些服务包括以可信和安全的方式交换信息所需的身份验证和安全会话建立。这些服务对于许多智能交通系统 (ITS) 应用和服务至关重要，包括时间关键型安全应用、自动驾驶、ITS 站点的远程管理 (ISO 24102-2) 以及路边/基础设施相关服务。 [外文原描述]： This document contains specifications for a set of ITS station security services required to ensure the authenticity of the source and integrity of information exchanged between trusted entities, i.e.: — between devices operated as bounded secured managed entities, i.e. "ITS Station Communication Units" (ITS-SCU) and "ITS station units" (ITS-SU) as specified in ISO 21217; and — between ITS-SUs (composed of one or several ITS-SCUs) and external trusted entities such as sensor and control networks. These services include the authentication and secure session establishment which are required to exchange information in a trusted and secure manner. These services are essential for many intelligent transport system (ITS) applications and services, including time-critical safety applications, automated driving, remote management of ITS stations (ISO 24102-2), and roadside/infrastructure-related services.
