Trust Relationships and Single Sign-on in Grid Based Data Warehouses
نویسندگان
چکیده
This project proposes a Grid system for a pre-defined virtual organisation, to facilitate the operations of a non-governmental organisation (NGO) with a specific set of initiatives, operating within a specific demographic boundary. The framework for this project is essentially an OGSAbased Grid Services architecture, comprising distributed data warehouse sources. Authentication and access control in such a system requires designers to establish appropriate trust relationships across trust-boundaries. This paper focuses on this particular security aspect, exploring authentication, single sign-on, delegation, and authorization mechanisms, as supported by the Globus Toolkit’s Grid Security Infrastructure, to establish trust relationships and manage credentials.

A Novel Two-Level Trust Model for Grid
Trust is hard to establish in a service-oriented grid architecture because of the need to support end user single sign-on and dynamic transient service. In order to enhance the security by the Grid Security Infrastructure (GSI), this paper proposes a two-level trust model and the corresponding trust metrics evaluation algorithms. The upper level defines the trust relationships among Virtual Org...

متن کاملMerging Similarity and Trust Based Social Networks to Enhance the Accuracy of Trust-Aware Recommender Systems
In recent years, collaborative filtering (CF) methods are important and widely accepted techniques are available for recommender systems. One of these techniques is user based that produces useful recommendations based on the similarity by the ratings of likeminded users. However, these systems suffer from several inherent shortcomings such as data sparsity and cold start problems. With the dev...
