A Novel Approach to Detect Sybil Attack in VANET
نویسندگان
چکیده
Vehicular Ad-hoc Network (VANET) is vulnerable to many security threats including Sybil attack due to its open infrastructure. In this paper we have proposed a scheme to detect Sybil attacks using Digital Signature. The infrastructure needed includes vehicles, Road Side Units (RSUs) and Department of Motor Vehicle (DMV). In Sybil attack the malicious node, called Sybil attacker, illegally claim multiple identities which are called Sybil nodes. In this paper a Sybil attacker has been designed and a simulation environment on real world conditions has been implemented using OSM maps, SUMO mobility generator and NS2 network simulator. The detection using Digital Signature does not require any vehicle to disclose its identity. Thus this scheme also preserves the privacy of vehicles.

Signal and Time Based Fuzzy Cluster Scheme to Detect Sybil Attack in VANET
Security is an important issue in the VANET environment and the Sybil attack affects it the most. In Sybil attack a node illegally claims itself as a legitimate node using multiple identities. This paper systematically analyses about Sybil attack and its effect in the VANET. We establish a Signal and Time clustering (STC) algorithm to detect the Sybil attack in VANET. The scheme provides a low ...
متن کاملDetection of Sybil Attack in VANETs by Trust Establishment in Clusters
Vehicular ad hoc networks (VANET) are a class of ad hoc networks build to ensure the safety of traffic. Trust and security remain a major concern in VANET since a simple mistake can have catastrophic consequence. A crucial point in VANET is how to trust the information transmitted when the neighbouring vehicles are rapidly changing and moving in and out of range. The main aim of this paper is t...

Security is a condemnatory situation in the network at the instant of transference. Miscellaneous grouping of attacks become visible in the network. In this paper we will examine about Sybil Attack. The proposed technique is the major idealization of our effort to provide elevated security to the network from Sybil attack using timestamp approach. Our proposed effort focused to diminish the iss...
متن کاملSybil Node Detection and Prevention Approach on Physical Location in VANET‟S
Vanet is the branch of networking which deals with the communication of data between different vehicles. The vehicles have been designed with sensors that communicate with RSU and other vehicles available in the range. In the vanet network various attackers perform attack on the network to stop the communication of different vehicles. This attack can make collision between different nodes. The ...
متن کاملDistributed Sybil Attack Detection in VANET
Security and Privacy are among the most important concerns in Vehicular Ad-hoc Networks (VANET). Widely accepted privacy preserving communication scheme in VANETcommunity -that is using pseudonyms –has left open doors for some security problems such as Sybil attack. In this paper, we have proposed an efficient approach detecting this attack while preserving privacy of vehicles in the network.
