Privacy-preserving route reporting scheme for traffic management in VANETs

摘要: With the large increase in number of registered vehicles, congestion and slow traffic problems are expected to worsen. Vehicular Ad Hoc Networks (VANETs) can play a great role avoiding these by sending guidance vehicles pursue alternative routes. However, published schemes require report their future routes which seriously violate privacy. In this paper, we present privacy-preserving route reporting scheme that suits VANET-enabled management rather than warning after happens. Vehicles provide encrypted segment-based information road side units (RSUs). Instead one message for each segment, all segments' data be collected using homomorphic encryption. RSUs compute encryption segment without knowing actual vehicles. Each RSU shares vehicles' with center (TMC), decrypts total at different segments individual Then, it conducts analysis sends predictions recommendations back RSUs. Passing solicit hints from on condition order decide take an alternating if there is potential or its main route. Our evaluation results demonstrate our preserve privacy drivers' efficient secure way.
