In this paper, we address the problem of trust management in multi-cloud environments using a trust management architecture based on a group of distributed Trust Service Providers (TSPs). These are independent third-party providers, trusted by Cloud Providers (CPs), Cloud Service Providers (CSPs) and Cloud Service Users (CSUs), that provide trust related services to cloud participants. TSPs are...

Trust Management represents a vital component for the protection of business transactions. This paper considers the application of a relational-based model for Trust Management in Electronic Payment Systems. We introduce a generic payment model that provides a good framework to validate our trust model. We use the special features, new extensions and relational techniques provided by the Trust ...

Participatory sensing is an emerging paradigm in which citizens everywhere voluntarily use their computational devices to capture and share sensed data from their surrounding environments in order to monitor and analyze some phenomenon (e.g., weather, road traffic, pollution, etc.). Interest in participatory sensing systems has risen since a large mobile sensor network can now be opportunistica...

Trust transfer is a common technique employed in trust management systems to establish relationships between parties that are strangers. It is also well known that trust is not always transferable. That is, given an existing trust relationship, it may or may not be possible to derive new trust from it. In particular, it is not known under which constraints trust is transferable. In this paper w...

Energy consumption is one of the most important parameters for evaluation of a scheme proposed for wireless sensor networks (WSNs) because of their resource constraint nature. Comprehensive comparative analysis of proposed reputation-based trust management schemes of WSNs from this perspective is currently not available in the literature. In this paper, we have presented a theoretical and simul...

The literature on network management is extensive. However, it generally explores network structures, neglecting the impact of management strategies. In this article we assess the effect of management strategies on network outcomes, providing empirical evidence from 119 urban revitalization networks. We go beyond current work by testing a path model for the determinants of network outcomes and ...

The open, sharing and anonymous nature of peer-to-peer (P2P) network has offered opportunities and threats for the development of distributed computing technology. One feasible way to minimize threats is to establish the reputation-based global trust model. Most of current trust mechanisms are not only unable to restrain effectively such malicious behavior as collusive attacks, but also take no...

Trust is crucial for mobile communications. However, how to manage trust in mobile enterprise networking among various mobile devices is problematic for companies using mobile enterprise solutions. This paper presents a trust management system in an enterprise’s virtual private networks (VPN). The system supports confidential content management and overcomes the diversity support of security in...
