The objective of this paper is to contribute to the development of a rigorous discipline for designing trust management mechanisms in online communities. The importance of such a discipline for management science is without question: trust is a precondition for the continued existence of any market and organization in general. Furthermore, several properties of online interaction are challengin...

In a Cyclic Mobile Ad Hoc Network (CMANET) where nodes move cyclically, we formulate trust management problems and propose the cTrust scheme to handle trust establishment and aggregation issues. Unlike trust management in conventional peer-to-peer (P2P) systems, trust management in MANETs is based on simple neighbor trust relationships and also location and time dependent. In this paper, we foc...

Trust between people engaging in economic transactions affects the economic growth of their community. Reputation management systems, such as the Feedback Forum of eBay Inc., can increase the trust level of the participants. We show in this paper that experimental economics can be used in a controlled laboratory environment to measure trust and trust enhancement. Specifically, we present an exp...

Most of the existing approaches to trust management focus on the issues of assessing the trustworthiness of other entities and of establishing trust between entities. This is particularly relevant for dynamic, open and distributed systems, where the identity and intentions of other entities may be uncertain. These approaches offer methods to manage trust, and thereby to manage risk and security...

This work proposes a new trust management system (TMS) for the Internet of Things (IoT). The wide majority of these systems are today bound to the assessment of trustworthiness with respect to a single function. As such, they cannot use past experiences related to other functions. Even those that support multiple functions hide this heterogeneity by regrouping all past experiences into a single...

The concept of trust has become popular in public debate and academic analysis. In high income countries this interest is associated with concern for the decline of trust in governments and professionals, and in developing countries has been prompted by debates around the motion of social capital. Trust has been identified as a major factor influencing such things as capital investment, relatio...

Applying current existing trust models or trust management systems on mobile computing environments require extracting user’s trust standards in different contexts, user’s experience or feedback dissemination and user’s decision about trust or distrust. However mobility, uncertainty and heterogeneity of mobile computing environments make trust management much more complicated, so they are inade...

Nowadays, peer-to-peer (P2P) streaming systems have become the most popular way to deliver multimedia content over the internet due to their low bandwidth requirement, high video streaming quality, and flexibility. However, P2P streaming systems are vulnerable to various attacks, especially pollution attacks, due to their distributed and dynamically changing infrastructure. In this paper, by ex...

The open and dynamic nature of modern distributed systems and pervasive environments presents significant challenges to security management. One solution may be trust management which utilises the notion of trust in order to specify and interpret security policies and make decisions on security-related actions. Most trust management systems assume monotonicity where additional information can o...
