诊断链路连接器安全

[中文适用范围]： 本文件介绍了一组建议措施，用于在将正常运行受到车辆外部来源干扰的设备（外部测试设备、数据收集设备等）连接到车辆诊断系统时提高车辆安全运行的可能性。术语“诊断系统”旨在作为一种通用方式，指代可能将诊断命令注入系统的所有不同方式。本文件中的指南旨在提高安全性，而不会显著影响特许经销商或独立售后市场外部测试工具执行合法诊断和维护功能的能力。目标是仅当车辆处于安全状态时才允许执行侵入服务，这样即使侵入服务是出于敌对意图而发起的，这种服务的后果仍然是可以接受的。 [外文原描述]： This document describes a set of recommended actions to take to increase the likelihood of safe vehicle operation when a device (external test equipment, data collection device, etc.) whose normal operation has been compromised by a source external to the vehicle is connected to the vehicle’s diagnostic system. The term “diagnostic system” is intended to be a generic way to reference all the different ways that diagnostic commands might be injected into the system.The guidance in this document is intended to improve security without significantly impacting the ability for franchised dealer or independent aftermarket external test tools to perform legitimate diagnosis and maintenance functions.The goal is that intrusive services are only allowed to be performed when the vehicle is in a Safe State such that even if the intrusive service were to be initiated with adversarial intent the consequences of such a service would still be acceptable.Cross Reference:
