Probabilistic trust models in network security
… motivation of using the notion of probabilistic trust as an approach to security sensitive decision making in modern open and global computing systems. In such systems any principal A uses the outcomes of past interactions with another principal B to construct a probabilistic model approximating …

Trust models for mobile content-sharing applications
… users filter out irrelevant content by running trust models. A trust model is a piece of software that keeps track of which devices are trusted (for sending quality content) and which are not. Unfortunately, existing trust models are not fit for purpose. Specifically, they lack the ability to: …

An Integrated Literature Review of Trust and Well-being and Implications for Trust Models and Positive Psychology
Trust has not yet been explored by positive psychologists. This paper reviews the literature on trust, discusses four well-being models, summarizes the relationship between trust and well-being and considers implications. Two main conclusions are reached. First, a strong and significant …

A synergistic reputation-policy based trust model for Grid resource selection
… the context of Grid computing, reputation-based trust management systems are playing an increasingly important role for supporting coordinated resource sharing and ensuring provision of quality of service. However, the existing Grid reputation-based trust management systems are considered limited …

Trust Management for Complex Agent Groups
… it is hard or impossible to establish trust between agents and it can greatly affect the operation of the systems. Several trust models have been proposed to assist agents to make decisions during moments of uncertainty. Nevertheless, most of the existing works focus on trust evaluation …

Models for Privacy in Ubiquitous Computing Environments
… private communication, we present a model for trustworthy routing, with a policy specification language that is computationally efficient to enforce. We show how quantitative trust models can be used to find trustworthy paths of communication and explore various semantic models of trust. For …

Provisioning of secure Multi-Agent Systems (MAS) based on trust contracts
… of an agent based system was created and trust accuracy levels based on the proposed mechanism were evaluated to establish the significance of the proposed security scheme; and (if) a security-aware agent-oriented shopping mall system was designed and implemented to demonstrate the …

The role of trust as a mediator in the relationship between technology factors and intention to accept internet banking in Nigeria
… banking and examined the mediating role of trust between technology factors and the intention to accept an internet banking. This study reviewed related technology acceptance theories and trust models. The decomposed theory of planned behaviour, innovation diffusion theory and …

A trust based approach to mobile multi-agent systems.
… and understanding of the incorporation of trust into the paradigm of mobile multi-agent systems. Trust deliberation is a soft security approach to the problem of mobile agent security whereby an agent is protected from the malicious behaviour of others within the system. Using a trust …

Building trust in cross-cultural relationships: Active trust through culture mobilisation in Finnish-Indian project teams
This thesis examines trust building in Finnish-Indian distributed teams engaged in knowledge-intensive project work. To understand how actors build trust in the context of cultural distance and virtual collaboration, dynamic approaches to trust building and culture were adopted. The data were …

Evaluation of Trust in the Internet Of Things: Models, Mechanisms And Applications
… blooming era of the Internet of Things (IoT), trust has become a vital factor for provisioning reliable smart services without human intervention by reducing risk in autonomous decision making. However, the merging of physical objects, cyber components and humans in the IoT infrastructure has …

Agoric computation: trust and cyber-physical systems
… inherently dynamical functional concepts such as trust and reliability, which present special challenges when scaling from small to large systems of agents. To overcome such challenges, it is useful to adopt a unified approach which we term agoric computation, integrating logical, mathematical and …

Quantifying Trust and Reputation for Defense against Adversaries in Multi-Channel Dynamic Spectrum Access Networks
… reports. Hence, there is a need to quantify the trustworthiness of radios that share spectrum sensing reports and devise malicious node identification and robust fusion schemes that would lead to correct inference about spectrum usage. In this work, we propose an anomaly monitoring technique that …

Trust Management Systems: Reference Architecture and Personalization
Trust is the cornerstone of success in any relationship between two or more parties. Generally, we do not socialize, seek advice, consult, cooperate, buy or sell goods and services from/to others unless we establish some level of mutual trust between interacting parties. When e-commerce was merging …
