A Novel Sybil Attack Detection Mechanism in Urban Vehicular Networks
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
In vehicular networks, moving vehicles are enabled to communicate with each other using inter vehicle communications as well as with road side units (RSUs) in vicinity via roadside-to-vehicle communications. In urban vehicular networks where the privacy, especially the location privacy of the vehicles should be guaranteed vehicles need to be verified in an anonymous manner. A wide spectrum of applications in such a network relies on collaboration and information aggregation among the participating vehicles. Without the identities of participants, such applications are vulnerable to the Sybil attack where a malicious vehicle masquerades as multiple identities, overwhelmingly influencing the result. The consequence of Sybil attack happening in urban vehicular networks can be vital. For example, in safety-related applications such as hazard warning, passing assistance and collision avoidance biased results caused by a Sybil attack can lead to severe car accidents. This paper presents a novel method for detecting sybil attacks in urban vehicular networks.
