Grid is concerned with the sharing and coordinated use of diverse resources in distributed "virtual organizations.?? The dynamic and multi-institutional nature of these environments introduces challenging security issues that demand new technical approaches. In particular, one must deal with diverse local mechanisms, support dynamic creation of services, and enable dynamic creation of trust domains...
The term ldquoGridrdquo refers to systems and applications that integrate and manage resources distributed across multiple control domains. The need to support the integration and interoperation of services which governed by the policies and rules of the real organizations introduces challenging security issues. This paper presents an approach which based on web services security specifications to...
Despite grids' popularity, virtual organizations (VOs) have yet to become a commodity technology in modern computing environments due to the complexity of managing them and difficulty of assuring user and VO isolation. Here, the authors describe the VO management approach taken by XtreemOS, a new grid operating system with native support for VOs that supports a wide range of computing resources, from...
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.
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
Grid manages resources and services distributed across multiple control domains. Grid computing provides people the way to share large mount of distributed resources and services that belong to different local domain. It also makes security problems more complicate, such as in the grid group communication. In this paper, we analyze security requirements of grid environment, especially for the secure...
