数据链接安全

[中文适用范围]： “该 SAE 推荐做法建立了一种统一做法，用于保护车辆组件免遭通过车辆数据链路连接器 (DLC) 进行“未经授权”的访问。该文件为机动车辆和工具制造商定义了安全系统。它将提供定制系统的灵活性以满足车辆制造商的安全需求。所讨论的车辆模块是那些能够通过数据链路连接器访问或更改固态存储器内容的车辆模块。不正确的存储器内容更改可能会损坏电子设备或其他车辆模块；给车辆带来风险“遵守政府立法要求；或冒汽车制造商安全利益的风险。本文件并不意味着不需要也不可能采取其他安全措施。” [外文原描述]： This SAE Recommended Practice establishes a uniform practice for protecting vehicle components from "unauthorized" access through a vehicle data link connector (DLC). The document defines a security system for motor vehicle and tool manufacturers. It will provide flexibility to tailor systems to the security needs of the vehicle manufacturer. The vehicle modules addressed are those that are capable of having solid state memory contents accessed or altered through the data link connector. Improper memory content alteration could potentially damage the electronics or other vehicle modules; risk the vehicle compliance to government legislated requirements; or risk the vehicle manufacturer's security interests. This document does not imply that other security measures are not required nor possible.Cross Reference: ISO/DIS14230,ISO9141/2,J1850_201510,J1930_201703,J2190
