Security in Automotive Radar and Vehicular Networks

As vehicles become more automated, security issues in automotive systems such as radar and dedicated short-range communication (DSRC) must be thoroughly examined. This paper provides an overview and comparison of the inherent security flaws in automotive radar and DSRC technologies. Existing implementations of automotive radar are vulnerable to a spoofing attack from a third party, potentially resulting in fatal accidents. While DSRC exhibits inherent resilience to spoofing attacks, it is still susceptible to similar types of attacks used against traditional Wi-Fi. This paper concludes with a discussion on the motivation for combining radar and DSRC into a joint system and an overview of the potential consequences of an insecure vehicular system.
