A Survey on Trust Management for Mobile Ad Hoc Networks

Abstract

Managing trust in a distributed Mobile Ad Hoc Network (MANET) is challenging when collaboration or cooperation is critical to achieving mission and system goals such as reliability, availability, scalability, and reconfigurability. In defining and managing trust in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication networks, and take into account the severe resource constraints (e.g., computing power, energy, bandwidth, time), and dynamics (e.g., topology changes, node mobility, node failure, propagation channel conditions). We seek to combine the notions of "social trust" derived from social networks with "quality-of-service (QoS) trust" derived from information and communication networks to obtain a composite trust metric. We discuss the concepts and properties of trust and derive some unique characteristics of trust in MANETs, drawing upon social notions of trust. We provide a survey of trust management schemes developed for MANETs and discuss generally accepted classifications, potential attacks, performance metrics, and trust metrics in MANETs. Finally, we discuss future research areas on trust management in MANETs based on the concept of social and cognitive networks.

Modeling and Analysis of Trust Management Protocols: Altruism versus Selfishness in MANETs

“…Trust should be contextdependent, and subjective, and cannot be assumed to be transitive or reciprocal. To address these unique trust properties, trust management for MANETs should consider the following design features: trust metrics must be customizable, evaluation of trust should be fully distributed without reliance on a centralized authority, and trust management should cope with dynamics and adverse behaviors in a tactical MANET [6].…”

Double Face Attack Resistant Trust Management Frameworks in Mobile Ad Hoc Networks: A Survey

“…The trust establishment component infers if a node can be trusted based on its trust level. Jin-Hee Cho [1] provided an overview on various potential attacks like Routing loop attacks, Worm hole attacks, Black hole attacks, Gray hole attack, Denial of Service (DoS) attacks, False information or false recommendation, Incomplete information, Packet modification /insertion, Newcomer attacks, Black mailing, Replay attacks, Sybil attacks, Selective misbehaving attacks in MANETs. Depending on design mode J. Cho [1] explained trust management scheme like secure routing, authentication, intrusion detection, access control, key management, and trust evidence distribution and evaluation etc.…”

“…Consequently, a trust management framework should particularly care of such trust-distortion attacks. A current survey shows [1][2] [6] that trust management frameworks dealing with trust-distortion attacks has not been provided. So a holistic view of existing trust management frameworks able to cope with trust-distortion attacks is provided.…”

Field size of random network coding in untrustworthy networks

“…In both cases, the trustworthiness is a level of trust, varying from 0 (complete distrust) to 1 (complete trust). Evaluation of the trust of different entities in various network environments have been widely studied, e.g., [6]- [11].…”
