Privacy-preserving secure relative localization in vehicular networks

Relative location information helps build vehicle topology maps. Such maps provide location information of nearby vehicles to drivers. In building a vehicle topology, one must consider various attacks on vehicular networks. Also the localization system should protect the drivers' identity privacy and make it difficult for the adversary to track vehicles. Many techniques have been proposed for relative positioning and location verification. Due to the high speed and the strict security requirements, the existing relative positioning and location verification techniques are not directly applicable to vehicular networks. Hence we present a scheme called P-SRLD 1 , which securely determines the relative locations of a set of wirelessly connected vehicles based on the relative locations of each vehicle's surrounding vehicles. P-SRLD uses cryptographic keys to authenticate location messages and uses a vehicle's cryptographic pseudonym to identify the vehicle to protect drivers...
