Trust based multi-path routing for end to end secure data delivery in manets

Abstract

Mobile Ad Hoc Networks (MANETs) are comprised of highly mobile nodes that communicate with each other without relying on a pre-existing network infrastructure. Therefore they are ideally suited for use in rescue and emergency operations. These applications have increased security requirements with low acceptable delays, in order to provide high quality service. However, MANETs were not designed with security protection in mind and they are prone to several attacks. Communication in mobile ad hoc networks comprises of route discovery and data transmission phases.In an adverse environment, both these phases are vulnerable to a variety of attacks. A misbehaving node can abide well in the route discovery phase and hence be placed on utilized routes. Later, it could tamper with the in-transit data in an arbitrary manner and degrade the network performance. This behavior can be nullified by securing the data transmitted. In this paper, we propose a novel method to enhance security in both phases. We present the design of a routing protocol based on trust, which ensures secure and undisrupted delivery of transmitted data. An end to end encryption technique is used to self encrypt the data without the necessity of a cryptographic key. Results show that our method is much more secure than other existing trust based multipath routing protocols.

Secure Data Transmission Through Node-Disjoint on Demand Multipath Routing in Manets

“…2. It is observed from the results that SDNMR performs better than SecMR [41] and protocol [42] because they do not consider selfish node attacks. SecMR is not addressing any kind of data security other than the discovery of secured multiple node-disjoint paths.…”

“…It is observed from the in-depth analysis of literature that most of the protocols were proposed to follow trust based security measurements to maintain multiple paths. A little work as [42] is providing both route security and data security. But unable to address attacks by selfish nodes which drop the data packets to save their battery power.…”

“…During data transmission after the route discovery process, the proposed protocol, SDNMR, uses trust based metrics to control data loss due to selfish node attacks. Most recent work which is more relevant to our work is presented in [42] but that work used trust based route discovery process followed by cryptographic based data security. Moreover, it is mentioned that the trust value of each node is calculated as a discrete value of either 0 or 1.…”

“…Since our secure protocol SDNMR is inspired from the previous work [41], [42], simulation results of SDNMR are compared with that work.…”

Attack Resistance Dynamic Detection and Data Trust Routing in MANET

“…The concept of "Trust" initially derives from social sciences and is well-defined as the degree of particular certainty about the behaviours of a specific entity [7]. Blaze et al [8] first introduced the term "Trust Management" and recognised it as a discrete factor of security service area in networks and explained that "Trust organization provides a unified approach for specifying and understanding security policies, credentials, and relationships."…”
