摘要：Vehicular ad hoc networks support a wide range of
promising applications including vehicular sensing networks, which enable vehicles to cooperatively collect and transmit the aggregated traffic data for the purpose of traffic monitoring. The reported literatures mainly focus on how to
achieve the data aggregation in dynamic vehicular environment, while the security issue especially on the authenticity
and integrity of aggregation results receives less attention. In this study, we introduce a basic aggregation scheme which could aggregate the data and the message authentication codes by using syntactic aggregation and cryptographic aggregation. To tolerate
duplicate messages and further improve the aggregation performance, we introduce a secure
probabilistic data aggregation scheme based on Flajolet-Martin sketch and sketch proof technique. We also discuss the tradeoff between the bandwidth efficiency and the estimation accuracy. Extensive simulations and analysis demonstrate the efficiency and
effectiveness of the proposed scheme.
