Research teams collaborating across institutional, geographical and cultural boundaries are increasingly common. Funding agencies including the National Science Foundation (NSF) and National Institutes of Health (NIH) strongly encourage virtual organization building and collaboration across institutions and disciplines. A set of software tools that enables scientists to efficiently share information...
Due to the permanently increasing complexity of products, and their related engineering processes, an appropriate IT infrastructure is required by small and medium-sized enterprises (SMEs) to enhance collaboration by exchanging engineering services. At the Information Systems Institute, research has been carried out on fostering collaboration in enterprise networks from automotive component supplier...
With the increasing complexity of dynamic and collaborative computing environments in Grid, access control has become a critical factor. Several approaches have been proposed in grid environment for scalable and efficient authorizations that are either VO-centric or Resource-centric. Reviewing different kinds of proposed authorization systems, we find out that VO-level and Resource-level authorization...
In this paper we are focusing on the minimum requirements to be addressed in order to demonstrate a inter-node communication within a Virtual Organisation (VO) using the method of Self-led Critical Friends (SCF). The method is able to decide paths that a node can choose in order to locate neighbouring nodes by aiming at realizing the overhead of each communication. The weight of each path will be...
Since 1970's, business environment had changed fundamentally. The customer's demand is various and personal, the market competition is becoming more intense, the enterprise's competitive advantage depends on the market strain capacity of the enterprise. The collaborative design grid platform is based on the advanced networking and the middleware technology. It provides the long-distance design task...
With the increasing complexity of dynamic and collaborative computing environments in grid, security management has become a critical factor. Although several approaches have been proposed, fully decentralized and efficient authorization management is still a challenging problem. We propose an access control scheme based on a group-based RBAC model for grid computing environments. By separating the...
The increasing complexity and dynamics of grid environments have posed great challenges for secure and privacy-preserving collaboration in a virtual organization. In this paper, we propose PEACE-VO, a secure policy-enabled collaboration framework for virtual organizations. PEACE-VO employs role mapping to define trust relationships across autonomous domains. Nevertheless, a critical issue emerges...
Grid is becoming an interesting and challenging environment supporting both old and new services for cooperative applications, which promote individual enterprises engaged in a collaborative community. This cooperation pressure results in an increased focus on the interconnection of member enterprises within virtual organization that necessitates the new highly scalable networking technology. Accordingly,...
