survey on Sybil Attack defense mechanisms in wireless ad hoc networks
Journal of Network and Computer Applications, 2018Co-Authors: Amol Vasudeva, Manu SoodAbstract:Abstract Wireless ad hoc networks are vulnerable to Sybil Attacks due to the broadcast nature of the wireless medium and an absence of central authority. In a Sybil Attack, an adversary illegitimately claims to have multiple imaginary identities, called Sybil nodes. This Attack is capable of vitiating various operations of these networks such as data aggregation, voting-based mechanisms, fair resource allocation schemes, misbehavior detection, and routing mechanisms. In this paper, we present a survey on the most promising techniques offered thus far to defend the three classes of ad hoc networks, i.e., Mobile Ad hoc Networks, Wireless Sensor Networks, and Wireless Mesh Networks, from the Sybil Attack. The techniques include symmetric cryptography using a central authority, random key pre-distribution (key pool, single-space pairwise, and multi-space pairwise), radio resource testing, received signal strength indicator, time difference of arrival, neighborhood data, passive ad hoc Sybil identity detection, passive ad hoc Sybil identity with group detection, and energy trust-based system. Specifically, we analyze various approaches to mitigate the Sybil Attack, together with their advantages and disadvantages. We emphasize making all of the concepts very clear and easily understandable to learners and researchers who are interested or planning to work in this area. To achieve this clarity, we illustrate all of the Sybil defense mechanisms with suitable examples and diagrams. In addition, we discuss the challenging research issues and future directions for mitigating the Sybil Attack in wireless ad hoc networks.

a vampire act of Sybil Attack on the highest node degree clustering in mobile ad hoc networks
Indian journal of science and technology, 2016Co-Authors: Amol Vasudeva, Manu Sood, Prem PrakashAbstract:Objective: This paper aims at analyzing the devastating effect of Sybil Attack in Mobile Ad hoc NETworks (MANETs) that use the Highest Node Degree based Clustering scheme for routing. Method/Analysis: A Sybil Attack can disrupt the highest node degree based clustering scheme in MANETs by impersonating the identity of a legitimate node. An Attacker will put all its efforts in forcibly electing its prey node as the leader of a cluster. In making its mission successful, an Attacker uses a number of ghost identities to interact with the prey node, and hence increasing the connectivity of that prey node. It can achieve this by allowing its multiple Sybil nodes to communicate directly with a legitimate prey node. In other words, all the Sybil nodes contribute to increase the node degree of a particular prey node, so as to make it a cluster head. The Sybil Attack can play the same trick on the same prey node in every cluster formation process by following the direction and movement the prey node. After making this prey node as a cluster head the multiple Sybil nodes can start sucking its battery by communicating with the bogus messages. Once the battery of the prey node is drained completely, the Sybil Attacker can impersonate its identity to further disrupt the network system. Findings: We have used Java language to simulate the vampire act of Sybil Attack in MANETs. All the results obtained from the experiments prove that a Sybil Attack succeeded with high probability, in forcibly re-electing the same prey node as a leader of the cluster. Novelty: The vampire act of Sybil Attack on the maximum connectivity based clustering is shown for the first time in this paper.

Perspectives of Sybil Attack in Routing Protocols of Mobile Ad Hoc Network
Lecture Notes in Electrical Engineering, 2013Co-Authors: Manu Sood, Amol VasudevaAbstract:It is cumbersome to achieve the security in a mobile ad hoc network due to its open nature, dynamically changing topology, lack of infrastructure and central management. A particular harmful Attack that takes the advantage of these characteristics is the Sybil Attack, in which a malicious node illegitimately claims multiple identities. Two routing mechanisms vulnerable to the Sybil Attack in the mobile ad hoc networks are multi-path routing and geographic routing. In addition to these routing protocols, we show in this paper that the Sybil Attack can also disrupt the head selection mechanism of various cluster-based routing protocols such as lowest id, highest node degree and mobility based clustering. To achieve this, we illustrate to have introduced a category of Sybil Attack in which the malicious node varies its transmission power to create a number of virtual illegitimate nodes called Sybil Nodes, for the purpose of communication with legitimate nodes of the MANETs.

Sybil Attack ON LOWEST ID CLUSTERING ALGORITHM IN THE MOBILE AD HOC NETWORK
International Journal of Network Security & Its Applications, 2012Co-Authors: Amol Vasudeva, Manu SoodAbstract:It is quite a challenging task to achieve security in a mobile ad hoc network because of its open nature, dynamically changing topology, lack of infrastructure and central management. A particular harmful Attack that takes the advantage of these characteristics is the Sybil Attack, in which a malicious node illegitimately claims multiple identities. This Attack can exceedingly disrupt various operations of the mobile ad hoc networks such as data aggregation, voting, fair resource allocation scheme, misbehavior detection and routing mechanisms etc. Two routing mechanisms known to be vulnerable to the Sybil Attack in the mobile ad hoc networks are multi-path routing and geographic routing. In addition to these routing protocols, we show in this paper that the Sybil Attack can also disrupt the head selection mechanism of the lowest ID cluster-based routing protocol. To the best of our knowledge, this is for the first time that a Sybil Attack is shown to disrupt this cluster based routing protocol. To achieve this, we illustrate to have introduced a category of Sybil Attack in which the malicious node varies its transmission power to create a number of virtual illegitimate nodes called Sybil nodes, for the purpose of communication with legitimate nodes of the Mobile Ad Hoc Network. The variation in the transmission power makes the Sybil Attack more deadly and difficult to be detected.

a Sybil Attack detection scheme based on adas sensors for vehicular networks
Consumer Communications and Networking Conference, 2020Co-Authors: Kiho Lim, Tariqul Islam, Hyunbum Kim, Jingon JoungAbstract:Vehicular Ad Hoc Network (VANET) is a promising technology for autonomous driving as it provides many benefits and user conveniences to improve road safety and driving comfort. Sybil Attack is one of the most serious threats in vehicular communications because Attackers can generate multiple forged identities to disseminate false messages to disrupt safety-related services or misuse the systems. To address this issue, we propose a Sybil Attack detection scheme using ADAS (Advanced Driving Assistant System) sensors installed on modern passenger vehicles, without the assistance of trusted third party authorities or infrastructure. Also, a deep learning based object detection technique is used to accurately identify nearby objects for Sybil Attack detection and the multi-step verification process minimizes the false positive of the detection.

Location verification based defense against Sybil Attack in sensor networks
Lecture Notes in Computer Science, 2006Co-Authors: Debapriyay Mukhopadhyay, Indranil SahaAbstract:Security is a major concern for a large fraction of sensor network applications. Douceur first introduced the notion of Sybil Attack [4], where a single entity(node) illegitimately presents multiple identities. As the nodes in sensor networks can be physically captured by an adversary, Sybil Attack can manifest in a severe form leading to the malfunction of basic operational protocols including routing, resource allocation and misbehavior detection. In this study, we propose a location verification based defense against Sybil Attack for sensor network where we assume that the network is consisted of static sensor nodes. We report quantitatively about the probability of not being able to detect Sybil Attack. This probability is indicative of the usefulness of our proposed protocol.
