“…In addition, there have been lots of work on trust dynamics too including trust prediction [7], [8], propagation [9], [10] and aggregation [10], [11]. These are all important trust and reputation techniques to detect or predict any malicious behaviors and thus enhance the overall security of the network.…”

The quality of information is crucial for decision making in many dynamic information sharing environments such as sensor and tactical networks. Information trustworthiness is an essential parameter in assessing the information quality. In this paper, we present a trust model to evaluate the trustworthiness of information as well as information publishing entities based on information provenance. In our trust model, decision makers can give an evaluation on the information they receive and further adjust the evaluation result to a more accurate value by considering two factors: information similarity and path difference. We introduce Collusion Attacks that may bias the computation and present a mechanism to detect and reduce the effect of Collusion Attacks. Based on the final adjusted information trust, feedback is given to the information publishing nodes to adaptively update their trust scores. Therefore, our collusion-resistant scheme can dynamically assess the trustworthiness of information as well as participating entities in a network and thus effectively enhance the network security. Detailed analysis of the proposed approach is presented along with simulation results.

“…In this work, we use the terms a node and an entity interchangeably to represent heterogeneous entities (or nodes) above. Military tactical networks typically have a hierarchical structure where a commander makes critical decisions to control all other entities in the network [1]. In this scenario, for the commander, it is critical to perceive an accurate view towards other entities for making right decisions.…”

“…GlobalTrust has the following unique contributions: (1) it provides an accurate, consistent view on the reputation of all nodes and detects malicious nodes in the network; (2) it can effectively deal with various attack behaviors; and (3) it outperforms the existing reputation schemes (i.e., two schemes in PeerTrust [3]) in terms of view consistency and resilience against various attack behaviors.…”

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.
