Vehicular Platoon Communication: Cybersecurity Threats and Open Challenges

Vehicular platooning is an emerging technology that promises to save space on congested roadways, improve safety and utilise less fuel for transporting goods, reducing greenhouse gas emissions. This technology will draw the attention of attackers seeking to profit or prove themselves to their peers by disrupting the platoons. A platoon has several attack surfaces that attackers can exploit to achieve their goals (either personal or financial). This paper aims to discuss various attacks that the attackers can launch against platoons by exploiting wireless communication weaknesses. Furthermore, we will present different known strategies which are currently used to defend platoons from attackers. This paper's primary contribution we believe will help new researchers in this domain, as well as automotive industries and smart cities planners.
