摘要
汽车智能网联化的发展赋予车辆更多功能属性,也提高了人们的驾驶舒适度,同时,也伴随带来了互联安全风险,如何提高车内总线传输安全性成为亟待解决的关键问题。基于身份认证与时间同步的有效手段,提出一种满足车载总线安全通信的方法,并将该方案在NXPS32系列平台进行部署搭建,最后,通过模拟网络攻击行为进行测试验证,通过对测试结果的分析,验证了该方法的有效性与安全性。并对车载总线存在的潜在复杂攻击场景进行了展望。
Withing the development of intelligent onautomotive,vehicles with more functional attributes and improving people’s driving comfort.At the same time,it has also brought the risk of cybersecurity.How to improve the cybersecurity of in-vehicle network has become a key problem to be solved.A securitymethodbasedon identity authentication and time synchronization has to meet the requirement of in-vehicle network secure communication.Andbuilding the demo system based on the method(NXP S32 development board).Finally,itconducts test to verifies the effectiveness and security of this method through analysis of test results.And making the prospects for the potential complex attack scenarios of in-vehicle bus.
