Distributed 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.
متن کاملEfficient Detection of Sybil Attack Based on Cryptography in Vanet
Vehicular communications play a substantial role in providing safety transportation by means of safety message exchange. Researchers have proposed several solutions for securing safety messages. Protocols based on a fixed key infrastructure are more efficient in implementation and maintain stronger security in comparison with dynamic structures. The purpose of this paper present a method based ...
متن کاملMitigation of Sybil Attack Using Location Aware Nodes in VANET
VANETs also called as intelligent transportation system (ITS) in which vehicles communicate to provide timely information. Their aim is to provide security, information and management of network. Instead of their many advantages vehicular network is prone to various attacks. In this research removal of Sybil attack in which node creates its multiple identities and it can be affected by various ...
متن کاملEfficient and Feasible Methods to Detect Sybil Attack in VANET
Large scale node to node systems face security threats from malfunction or hostile remote computing elements. Node to node system commonly relies on the existence of multiple independent remote entities to mitigate the threat of hostile nodes. Sometime single faulty node can produce various identities leading to control of substantial fraction of the system. These attacks are called Sybil attac...
متن کاملA Novel Approach to Detect Sybil Attack in VANET
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...
