Abstract

一种车辆诊断系统、方法及装置，用以解决使用长期密钥进行车辆诊断所导致的不安全影响。车辆诊断系统包括密钥管理系统和待诊断单元，密钥管理系统接收诊断设备发送的密钥授权请求，根据密钥授权请求生成临时密钥，并向诊断设备发送密钥授权响应，在密钥授权响应中携带该临时密钥，密钥管理系统将临时密钥配置给待诊断单元，以便于诊断设备和待诊断单元基于临时密钥完成诊断并得到诊断结果。其中，临时密钥独立于车辆中的长期密钥。通过配置临时密钥来完成车辆诊断，能尽量避免诊断设备接触到车辆中的长期密钥，这样不仅有助于保护车主的隐私数据，还能降低非法人员利用长期密钥控制车辆运行的可能性，提高车主的行车安全性。
