Abstract
A wireless vehicular network (WVN) is a particular type of intelligent transportation system that utilizes vehicle-to-everything (e.g., inter-vehicle and infrastructure-vehicle) communications to carry out different network operations. In the context of communicating cars, with the aid of a WVN, we can optimize traffic routing, minimize traffic congestion, improve road tolling infrastructure, assist smart city traffic planning, aid in road infrastructure expansions, achieve seamless in-vehicle entertainment services, increase electric vehicle charging performance [2], and most importantly enhance road safety. As per a survey conducted by the World Health Organization, there are annually over one million causalities worldwide due to car accidents. Eliminating such a high number of fatalities, even partially, is a challenge that motivates an increasing amount of research on WVNs. To enable the full functions of a WVN, we require the following three desirable features: ultra-high data rates, ultra-reliability, and ultra-low latency. These desirable features cannot be fully met by existing general wireless communication systems such as fifth-generation (5G) cellular systems or the dedicated short-range communication (DSRC) system. However, the forthcoming fifth-generation (5G) (B5G) or the sixth-generation (6G) technology is specifically designed with these desirable features in mind. Location information plays an important role in WVNs and even serves a foundation role in several key functional areas [3-5]. For example, many network operations of WVNs, such as location-based routing, depend critically on the location information of each vehicle in the network. Also, location information serves as the enabler of many services provided by WVNs, e.g., collision avoidance and location-based advertising. Considering the critical uses of localization information, its security becomes of pivotal importance. However, the reliability and correctness of a vehicle's reported location information cannot be fully guaranteed by existing techniques. Meanwhile, some privacy concerns on location information are emerging. This chapter addresses two key features for 6G location security, i.e., the security associated with localization services: (a) location verification systems (LVSs) [6], aiming at ensuring that the reportedly derived location is correct, and (b) location privacy techniques, aiming at preventing the disclosure of the position information to other entities. Lastly, we shed some light on new solutions based on quantum security to improve location privacy and verification.
