Various promising distributing computing paradigms such as Grids, P2P and Clouds have emerged over Internet. How to build the trust relationship among principals in such an open computing environment has become an important issue. Automated trust negotiation (ATN) approach aims to gradually build trust relationship between strangers through the interactively disclosing of credentials and security...
With the increasing prevalence of large scale cloud computing environment, researchers has draw more attention about how to provide software as a service through the internet. In this paper, a novel approach named vSaaS is proposed in iVIC platform, which is the virtual computing environment for HaaS and SaaS applications. The aim of this approach is to provide the software as a service from a cloud...
Grid computing has emerged as a new paradigm of distributed computing technology on large-scale resource sharing and coordinated problem solving. Based on a proposed Web service-based grid architecture, we have designed a service grid middleware system called CROWN which aims to promote the utilization of valuable resources and cooperation of researchers nationwide and world-wide. To address the issues...
A proposed grid middleware system includes specific enhancements to support the development and assessment of highly secure, dependable, service-oriented grid systems and applications. Service-oriented architectures can be defined as application architectures "within which all functions are defined as independent services.
Service-orientation is a highly useful means of developing flexible, agile, and dependable software systems, and is a paradigm that has been increasingly adopted into grid computing middleware. However, service-orientation brings with it new challenges in the fields of dependability and security that need to be addressed by the high assurance systems community in order to provide sufficient support...
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...
Based on a proposed Web service-based grid architecture, a service grid middleware system called CROWN is designed in this paper. As the two kernel points of the middleware, the overlay-based distributed grid resource management mechanism is proposed, and the policy-based distributed access control mechanism with the capability of automatic negotiation of the access control policy and trust management...
