Signal and Time Based Fuzzy Cluster Scheme to Detect Sybil Attack in VANET
نویسندگان
چکیده
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 complexity and low overhead solution which can be more efficient in a VANET environment.

A 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...
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...
متن کاملA Time-series Clustering Approach for Sybil Attack Detection in Vehicular Ad hoc Networks
Sybil attack is a security threat wherein an attacker creates and uses multiple counterfeit identities risking trust and functionality of a peer-to-peer system. Sybil attack in vehicular ad hoc networks is an emergent threat to the services and security of the system. In the highly dynamic environment of vehicular ad hoc networks, due to mobility and density of nodes, it is challenging to detec...
متن کامل7758 Sybil Attack Detection Technique for Vanets : a Novel Scheme
Vehicle adhoc networks (VANET) are an application of Mobile adhoc networks (MANET). VANET performs management of traffic very well. It also circulates safety information to drivers and passengers in the vehicle. Here, in this paper we have proposed a novel scheme of Sybil attack detection mechanism or algorithm by using which the trajectory path communication among vehicles for identification w...
متن کاملAccurate Sybil Attack Detection Based on Fine-Grained Physical Channel Information
With the development of the Internet-of-Things (IoT), wireless network security has more and more attention paid to it. The Sybil attack is one of the famous wireless attacks that can forge wireless devices to steal information from clients. These forged devices may constantly attack target access points to crush the wireless network. In this paper, we propose a novel Sybil attack detection bas...
