The Trust-Based MAC - Layer Security Protocol for Mobile Ad Hoc Networks

Abstract

In this paper, we develop a trust based security protocol based on a cross-layer approach which attains confidentiality and authentication of packets in both routing and link layers of MANETs. In the first phase of the protocol, we design a trust based packet forwarding scheme for detecting and isolating the malicious nodes using the routing layer information. It uses trust values to favor packet forwarding by maintaining a trust counter for each node. A node is punished or rewarded by decreasing or increasing the trust counter. If the trust counter value falls below a trust threshold, the corresponding intermediate node is marked as malicious. In the next phase of the protocol, we provide link-layer security using the CBC-X mode of authentication and encryption. By simulation results, we show that the proposed cross-layer security protocol achieves high packet delivery ratio while attaining low delay and overhead. B. Neighbor attackThe neighbor attack and the black hole attack prevent the data from being delivered to the destination. But the neighbor attacker does not catch and capture the data packets from the source node. It leaves the settings as soon as sending the false messages. C. Wormhole attackTwo malicious nodes share a private communication link between them. One node captures the traffic information of the network and sends them directly to other node. Warm hole can eavesdrop the traffic, maliciously drop the packets, and perform man-in-the-middle attacks against the network protocols.[6]. D. DoS (Denial of Service) attackWhen the network bandwidth is hacked by a malicious node [5], then it results to the DoS attack. In order to utilize precious network resources like bandwidth, or to utilize node resources like memory or computation power, the attacker inserts packets into the network. The specific instances of the DoS attack are the routing table overflow attack and energy consumption attack. E. Information Disclosure attackThe information disclosure attack aims at the privacy requirements of network. The confidential information's like A.

Evaluating the Research Trends and Techniques for Addressing Wormhole Attack in MANET

“…Hence, cross-layer approach comes as better alternative and was found to be adopted by various researchers e.g. Gopinath et al [31], Raja ram [32], and Djahel et al [33].…”

Handling Cross-Layer Attacks Using Neighbors Monitoring Scheme and Swarm Intelligence in MANET

“…A.Rajaram et al [12] have developed a trust based security protocol based on a MAC-layer approach which attains confidentiality and authentication of packets in both routing and link layers of MANETs.

Intrusion Detection Technique in Mobile Adhoc Network Based on Quantitative Approach

“…A number of trust building and clusterbased voting schemes have been proposed to enable the sharing and vetting of messages, and data, generated and gathered by IDS systems. Zhang and Lee describe a distributed and collaborative anomaly detection-based IDS for ad hoc networks [2,3]. AODV routing behavior and distributed network monitors for detecting run-time violation of the specifications [4].…”
