Cloud computing has been attracting the attention of several researchers both in the academia and the industry as it provides many opportunities for organizations by offering a range of computing services. For cloud computing to become widely adopted by both the enterprises and individuals, several issues have to be solved. A key issue that needs special attention is security of clouds, and tru...

TRUST MANAGEMENT SCHEMES FOR PEER-TO-PEER NETWORKS

Trust management has received a lot of attention recently as it is an important component of decision making for electronic commerce, Internet interactions and electronic contract negotiation. However, appropriate tools are needed to effectively specify and manage trust relationships. They should facilitate the analysis of trust specification for conflicts and should enable information on risk ...

The study of trust management in multi-agent system, especially distributed, has grown over the last years. Trust is a complex subject that has no general consensus in literature, but has emerged the importance of reasoning about it computationally. Reputation systems takes into consideration the history of an entity’s actions/behavior in order to compute trust, collecting and aggregating ratin...

A trust management framework is useful to ensure proper functioning of a mobile ad-hoc network (MANET). Trust metadata created by individual nodes, based on their observation of the behavior of other nodes in their vicinity, is required to be accessible to a trust authority (TA) (e.g., the network administrator) for prompt decision making (e.g., revoking malicious nodes). In this work, for secu...

The subjective trust relationship is uncertain in the open network; it has fuzziness and uncertainty of dual characteristics. Therefore, both features should be considered when setting up trust model. Cloud model was introduced to, a qualitative and quantitative transformation model; the investigation of subjective trust management, a brand new representation method of subjective trust was prop...

LIGHT is a project that is partially funded by the European Commission as an Innovation Action as part of the Horizon2020 program under grant agreement number 700321. LIGHT‘s objective is to create a Lightweight Infrastructure for Global Heterogeneous Trust management in support of an open Ecosystem of Stakeholders and Trust schemes. We show supported scenarios, motivate the necessity for globa...

A MANET, in order to work properly, needs its nodes to work collaboratively. This is not always the case, and thus tools are developed to detect and identify uncooperative nodes. In this paper we present TADSR, a protocol based on an already existing secure routing protocol on top of which it adds trust management features. Our aim is to detect rogue nodes, and also to improve the overall perfo...

Administration of Grid resources is a time consuming and often tedious job. Most administrative requests are predictable, and in general, handling them requires knowledge of the local resources and the requester. In this paper we discuss a system to provide automated support for administrative requests, such as resource reservation and user account management. We propose using trust metrics to ...

The success and competitive edge of enterprises has become increasingly dependent on the enterprises’ agility to become members in business networks that support their own business strategies. Therefore, integration solutions with their well-weathered strategic networks are no longer sufficient. Instead, there is need for more open business service ecosystems where previously unknown services a...
