摘要：in metropolitan vehicular system, where isolation, mainly the position isolation of unsigned medium is extremely afraid, unidentified confirmation of medium is essential. Accordingly, an assailant who is successful in counterfeit many hostile identifies can easily launch a Sybil attack, gaining a excessively huge authority. In this paper, we suggest a new Sybil harass discovery instrument, Footprint, using the path of medium for recognition while still protect their position isolation. More particularly, when a medium move toward a road-side unit (RSU), it aggressively stress an official communication from the RSU as the evidence of the manifestation time at this RSU. We plan a location-hidden official communication production method for two objectives: first, RSU mark on communication are signer indefinite so that the RSU position data is obscured from the resulted official communication; second, two official communication mark by the similar RSU within the equal given stage of time (provisionally linkable) are identifiable so that they can be utilized for recognition. With the sequential restriction on the link capability of two official communications, approved communication used for long-term classification are banned With this method, medium can produce a location-hidden route for location-privacy-preserved recognition by gathering a uninterrupted series of official communication. Use public association among path according to the correspondence explanation of two paths, Footprint can distinguish and consequently dismiss "communities" of Sybil trajectory. Thorough safety analysis and wide trace-driven replication display the effectiveness of Footprint.
