Cyber Security challenges in V2X and in vehicle network 2024-28-0035

Until recently, it was always assumed that only a computer network could be a potential Candidate for cyber-attacks. This perception changed sometime in the year 2007 when the EVITA project by the EU first considered the idea of protecting Automotive ECUs from cyber-attacks. The Automotive cybersecurity topic started gaining momentum when catastrophic repercussions of a cyber-attack using a Jeep Cherokee sometime around 2015. Out of multiple threats in various automotive inter and intra communication interfaces, V2X attacks are at their infancy, but are expected to become much more frequent in the coming years. Telematics, smart mobility, in-vehicle/mobility IoT, and other services require connected vehicles to share data with servers, apps, and various vehicle components. V2X involves V2I, V2V, V2N, V2C, V2P, V2D and V2G etc. The future of V2X will rely on new wireless communication technologies, such as DSRC and Cellular V2X (C-V2X), which have been in testing for the past few years. This paper focuses on identifying the cryptographic algorithm based on Automotive use cases and possible attack vectors. In vehicle Network and interface protection is getting protected with Sec Flash, Sec Boot, Sec NVM, Sec OC, Sec Life Cycle, Sec Debug port but when we consider V2X then we need to be smart enough to identify the security features in connection with abrupt cryptographic algorithm, as the exposure of data in multiple platform mode is too high here. We will further discuss in this paper about the external triggering which will have the potential to impact the Automotive data security, Functional adaptation in association with HSM to reduce the operational risks. We would also discuss the respective testing methodologies (Fuzz test, Penetration test) to achieve derived goals.
