Towards a Threat Model and Privacy Analysis for V2P in 5G Networks

In recent years, pedestrian and bicyclist fatalities have increased while roadway fatalities have remained relatively consistent. There is an emerging body of research on vehicleto-pedestrian (V2P) communication to reduce collision. However, the success of the real-life implementation of such a system is limited. Current technology and network spectrum are insufficient to support the fully functional V2P system. Research suggests that the low latency and high bandwidth of 5G technology would improve vehicle-pedestrian communication. Unfortunately, such systems raise security and privacy concerns. It is important to systematically analyze the security and privacy issues of such systems. This paper discusses the security and privacy issues of vehicle-pedestrian communication in 5G technology and analyzes the threat model of such applications using the STRIDE model. Such a threat model can help researchers and practitioners build secure V2P systems running over 5G networks.
