基于AUTOSAR规范的E2E安全通信的研究与实现

Research and Implementation of E2E Secure Communication Based on AUTOSAR

随着功能安全正成为汽车最重要的主题之一,汽车开放系统架构AUTOSAR在4.0版本中引入了功能安全概念,其中车载CAN总线通讯的功能安全作为重点研究对象,AUTOSAR对此制定了一系列开发规范文件。文章针对车载网络中的通信安全问题,对基于AUTOSAR架构的端到端(End-to-End,E2E)通信保护机制进行了研究,采用E2E Profile1的方法加以实现。实验表明,E2E通信保护机制可以有效的检测系统运行时通信链路中的故障并进行相应处理。

As functional safety is becoming one of the most important themes of automobile, the concept of functional safety is introduced in AUTOSAR4.0, in which the functional safety of the vehicle CAN bus communication is the key research object and AUTOSAR has set up a series of development specification documents for it. Aiming at the problems of communication safety in the vehicle network, this paper studies the end-to-end protection mechanism based on AUTOSAR architectureand uses the E2E Profilelto implement it. Experiments show that the E2E protection mechanism can effectively detect the faults in the communication links of the system and deal with them accordingly.
