Federation becomes pervasive in information sharing and collaborations over distributed systems, ubiquitous systems, and the Internet. Trust management plays a critical role to smooth collaborations and information sharing across different trust domains. The federation of trust management is a new direction for these networked systems. In this paper, the requirements and a set of evaluation met...

Trust management is emerging as a promising technology to facilitate collaboration among entities in an environment where traditional security paradigms cannot be enforced due to lack of centralized control and incomplete knowledge of the environment. However, prior art generally lack considerations on usable means to gather and disseminate experiential evidences, extract trust criteria from a ...

Study of trust in P2P network now is focus on how to effectively against various malicious behaviors such as providing fake or misleading feedback about other peers and the management of trust in a P2P environment. But the scotoma of portability that trust peer can join (leave) a certain P2P network at anytime and anywhere is seldom discussed. In this paper, a structured topology for trusts man...

Concern about vulnerabilities of IT systems is growing together with attention to risks of intrusive cyber-control over personal activities and data. This article discusses some new technologies that are being integrated into computing devices for realizing so-called Trusted Computing and Digital Rights Management systems, which can remotely attest their current hardware/software state and can ...

Trust management systems are vulnerable to so-called probing attacks, which enable an adversary to gain knowledge about confidential facts in the system. We present the first method for deciding if an adversary can gain knowledge about confidential information in a Datalog-based policy.

Trust management involves the identification and analysis of trust relations. However, adequately managing trust requires all the relevant aspects of trust to be addressed. Moreover, which aspects to address depend on the perspective of the trust management.

Trust has been viewed as an integral component of agent decision making in the context of multiagent systems (MASs). Various formal and semi-formal trust schemes, motivated by diverse considerations and influenced by various fields of study, have been proposed, implemented, and evaluated. We believe that there still exists a pressing need for developing a comprehensive trust management scheme t...

Trust is a major aspect of decision making when two parties are involved, and the lack of face to face exchanges of the Internet deeply changes relations and behaviours regarding the available services. The already existing trust management systems over the Internet are one way only. Either they allow a provider to tell what it expects from a client (identification, qualifications), either it a...

The development of complex applications that use the Peer-to-Peer computing model is restrained by security and trust management concerns, despite evident performance benefits. An example of such an application of P2P computing is P2P Massive Multi-user Online Games, where cheating by players is simple without centralized control or specialized trust management mechanisms. The article presents ...
