The realization of a pervasive context-aware service platform imposes new challenges for the security and privacy aspects of the system in relation to traditional service platforms. One important aspect is related with the management of trust relationships, which is especially hard in a pervasive environment because users are supposed to interact with entities unknown before hand in an ad-hoc a...

I nternet applications have evolved from centralized and private computing platforms to distributed and collaborative networked computing systems. Collaboration is a fundamental Internet computing capability, and collaborative computing represents a significant step toward the continued promotion of openness and social intelligence as Internet systems and applications evolve. However, trust and...

Trust management for peers in P2P network is very much important due to its open and anonymous nature. In this paper, we propose a reputation based trust management scheme for partially decentralized peer-to-peer file sharing systems. Reputation data is stored at the super node level. We calculate the reputation value for each file by using fuzzy logic inferences, which can better handle uncert...

In this paper we survey trust computation models for Internet of things (IoT) systems for the purpose of service management, i.e., whether or not to select an IoT device as a service provider. Future IoT systems will connect the physical world into cyberspace everywhere and everything via billions of smart objects, and are expected to have a high economic impact. To date there is little work on...

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...

Reliable, distributed applications based on Internet, such as e-commerce system rely heavily on trust path among involved parties. This article introduces an efficient trust model based trust service, Independent Trust Intermediary Service model using Smart Trust List, for trust management. Fundamentally, Independent Trust Intermediary Service is facilities for distributing certificates of CAs ...

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...

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 ...
