“…In [11], the authors proposed a survey of key management techniques targeted to only network-layer security. In [12], the authors proposed a framework to mitigate double-face attacks based on collecting both direct and remote recommendations. This framework is strong to conflicting behavior and onoff attacks with little extra overhead.…”

Instant collaborative group communication can be achieved by deploying Mobile Ad Hoc Networks (or MANETs) without any pre-plan and pre-existing infrastructure setup. However, the curbs thrown by these networks, motivate the necessity of a group key management framework to secure data traffic. In this context, significant research work done in the last decade and proved that the trust based frameworks deliver better performance than others. In MANETs, trust quantified as the belief held by a node about another node. It is evaluated based on the assessing node direct experiences with assessed node itself, if they are neighbors and recommendations from remote nodes in the network with which assessed node has a direct experience, if they are remote. However, the framework based on recommendations by other nodes in the network might ultimately lead to system failure due to the menace of unfair recommendations by selfish and malicious nodes. Lying and on-off attacks on the system are such type of attacks. This motivates us to work on a framework which is immune to aforesaid attacks and should be lightweight due to node's has limited computing resources. We propose a framework which scrutinizes dishonest recommendations based on the trust threshold value of remote nodes, distance from mean of trust recommendations and by maintaining a history of recommendations. Our simulation outcomes prove that proposed framework can deliver better network performance and resistance to lying and on-off attacks.

“…Arboit et al [10] introduced a computational reputation model considering accusations against nodes in MANETs. However, [9], [10] do not deal with a false recommendation attack that often significantly deters accurate reputation assessment. Some other existing reputation management schemes [11]- [14] evaluate reputation of a node subjectively based on the evaluator's direct observation, ultimately leading to inconsistent global reputation view.…”

Abstract-In a military tactical network where a trust authority (e.g., a commander) makes a decision during a mission, assessing the trustworthiness of participating entities accurately is critical to mission success. In this work, we propose a trust-based reputation management scheme, called GlobalTrust, for minimizing false decisions on the reputation of nodes in the network. In the proposed scheme, nodes may be compromised and provide incorrect opinions to the trust authority, who conducts reputation evaluation towards all nodes based on the provided opinions. GlobalTrust achieves three goals: (1) maintaining a consistent global view towards each node; (2) obtaining high resiliency against various attack patterns; and (3) attaining highly accurate reputation values of nodes. Through extensive simulations comparing GlobalTrust with other existing schemes, we show that GlobalTrust minimizes false decisions while maintaining high resilience against various attack behaviors. Specifically, under various attacks, GlobalTrust can achieve a highly accurate consistent view on nodes' reputations even when the number of malicious nodes is up to 40% of all participating nodes.

“…For any return to misbehaviour mode, an observer node should stretch out the required period the attacker should behave trustworthy to be able to be re-trusted. Moreover, It [12] is vulnerable to the bad mouthing attack since no mechanism is considered to differentiate between correct and false recommendations. Furthermore, we believe that the framework gets also immune to the conflicting behaviour attack since nodes' trustworthiness is evaluated based on both positive and negative recommendations received from all over the network.…”

Abstract-Trust management is a promising approach to conduct node's transactions and establish management interactions in distributed mobile ad hoc networks (MANETs). In MANETs, providing safe communication between mobile nodes, reorganization the position of nodes, handling misbehaviour are critical issues so trust management framework play very important role in MANETs. The characteristics of mobile ad hoc networks causes a number of challenges to security design such as lack of infrastructure, shared wireless medium, stringent resource constraints and highly dynamic topology. The inherent freedom in self-organized mobile adhoc networks (MANETs) introduces challenges for trust management; particularly when nodes do not have any prior knowledge of each other. Mainly, some trust management basis may be exploited to fulfill new attacks. Here, a holistic view on various trust management frameworks geared for MANETs is presented, capable to handle main existing attacks deceiving trustworthiness computation to mislead trust-based network operations, referred to as trust-distortion attacks. Besides, taxonomy of main identified trust-distortion attacks based on how the trustworthiness estimation of a node about another node is distorted is proposed. For each framework, a unified approach is used to describe the trust model, taking each component required for trust management as a guideline. Moreover, each framework is analyzed regarding its resistance against different trust-distortion attacks, the framework unique features, merits, demerits. Finally, different trust management frameworks resisting double face attacks are compared.Index Terms-Mobile ad hoc networks, Trust Management Framework (TMF), Double Face Attacks.
