Trust management in mobile ad hoc networks using a scalable maturity-based model

Abstract

International audienceIn this paper, we propose a human-based model which builds a trust relationship between nodes in an ad hoc network. The trust is based on previous individual experiences and on the recommendations of others. We present the Recommendation Exchange Protocol (REP) which allows nodes to exchange recommendations about their neighbors. Our proposal does not require disseminating the trust information over the entire network. Instead, nodes only need to keep and exchange trust information about nodes within the radio range. Without the need for a global trust knowledge, our proposal scales well for large networks while still reducing the number of exchanged messages and therefore the energy consumption. In addition, we mitigate the effect of colluding attacks composed of liars in the network. A key concept we introduce is the relationship maturity, which allows nodes to improve the efficiency of the proposed model for mobile scenarios. We show the correctness of our model in a single-hop network through simulations. We also extend the analysis to mobile multihop networks, showing the benefits of the maturity relationship concept. We evaluate the impact of malicious nodes that send false recommendations to degrade the efficiency of the trust model. At last, we analyze the performance of the REP protocol and show its scalability. We show that our implementation of REP can significantly reduce the number messages

An Elliptic Curve-Based Trust Management Protocol in Peer-to-Peer Networks

“…We have also presented a security analysis of the protocol, showing that the protocol has desirable features of anonymity, accountability and reliability in trust query and reporting processes. Our protocol is feasible for most of global reputation-best trust models, such as Trust [9], GTMS [10] and REP [11].…”

“…And (2) how to distribute, store, and access the trust value of peers securely [6]- [8]. A fair amount of work has been done related to the first issue [9]- [11]. However, The research in developing secure mechanisms of distribution and access trust value related to the second issue is scanty.…”

A multi-dimensional trust-aware cloud service selection mechanism based on evidential reasoning approach

“…To increase the flexibility of network computing systems, many researchers have proposed trust-based approaches, i.e., the trust information sharing mechanisms, algorithms for selecting entities to trust, evaluation mechanisms and so on in distributed systems, such as peer-topeer networks [2,3,17] , ad hoc sensor network [18] , ubiquitous computing, and electronic commerce communities. However, due to the uncertainty of the trust cognition and the inherent human subjective nature in the trust evaluation, there are still big challenges needed to be addressed.…”

Secure Trust Metadata Management for Mobile Ad-Hoc Networks

“…In some previous protocols [4,3], nodes themselves initiate requests to obtain trust metadata created by other nodes (recommendations). Requests are sent and replies are received based on the recommendation trust values of nodes, i.e., trust metadata for providing correct recommendations.…”

“…A trust management framework [1][2][3][4][5] is useful to ensure proper functioning of a mobile ad-hoc network (MANET). Nodes in a MANET generally lack hardware support for tamper resistance.…”
