In this paper we discuss how a Cloud Computing offering can co-exist in the GARUDA infrastructure. GARUDA is now an established Grid, having undergone two phases of evolution. Providing Cloud Computing support is essential to increase the outreach of Grid to more application developers and users. Grids may rely on private networks, whereas Clouds rely on Internet and the Service-oriented Architecture...
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...
Based on the researches of E-education GRID and Cooperative Intelligent Grid, a new cooperative intelligent grid based E-education platform was designed.
The scope of this paper is to discuss and analyze different approaches and solutions in which the interoperability between the Spatial Data Infrastructure (SDI) and the Grid environment is feasible. Most of the SDIs are exposed using Geospatial Web services, standardized by the Open Geospatial Consortium (OGC). The Grid environment was built to overcome the distributed computing problems regarding...
In the context of complex networks,such as Internet, security testing determines whether an implementation under test conforms to its specification. Testing was carried out in a centralized and sequential way. This is no longer applicable or feasible as systems to be tested have become increasingly complex and can be widely distributed. We present a new solution to evaluate how a distributed approach...
Network security is in a daily evolving domain. Every day, new attacks, virus or intrusion techniques are released. Hence, network devices, enterprise servers or personal computers are potential targets of these attacks. Current security solutions like firewalls, intrusion detection systems (IDS) and virtual private networks (VPN) are centralized solutions which rely mostly on the analyze of inbound...
Adapting existing distributed infrastructures to the Grid is a major aim of Germany's D-Grid initiative. As generic compute and data storage resources as well as management services for Virtual Organizations are well established in the D-Grid infrastructure, it is now possible for existing research communities to use these resources to enhance their existing infrastructures or develop new ones that...
The emergence of high-speed networks, Grid Computing, Service-Oriented Architectures, and an ever increasing ambient connection to mobile Internet has enabled an underpinning infrastructure for the development of dynamically formed, collaborative working groups known as Virtual Organizations (VOs). VOs provide strong motivation for investigation into the infrastructure, and in particular the security...
Today basically two grid concepts rule the world: service grids and desktop grids. Service grids offer an infrastructure for grid users, thus require notable management to keep the service running. On the other hand, desktop grids aim to utilize free CPU cycles of cheap desktop PCs, are easy to set up, but the availability towards users is limited compared to the service grid. The aim of the EDGeS...
Problem solving environments (PSEs) are increasingly important for scientific discovery. Today's most challenging problems often require multi-disciplinary teams, the ability to analyze very large amounts of data, and the need to rely on infrastructure built by others rather than reinventing solutions for each science team. The TeraGrid Science Gateways program recognizes these challenges and works...
The authors have been leading the GEO Grid project since 2005. This project is primarily aiming at providing an e-Science infrastructure for the worldwide Earth Sciences community. The GEO Grid is designed to virtually integrate all relevant data as a VO-enabled service based on Grid technology, and as such, is accessible as a set of services. This kind of infrastructure is demanded not only by geoscience,...
In providing the infrastructure for the accomplishment of general purpose computational grids the main concern is security. Still, by properly authenticating users and hosts and in the interactions between them, most grid implementations focus their safety concerns. The effective and competent exploitation of grid computing services needs sophisticated and secured resource management systems. The...
The emerging grid infrastructure presents many challenging security issues that demand new access approach due to its inherent heterogeneity, multidomain characteristic and highly dynamic nature. In order to protect the secure sharing and coordinated use of diverse resources in distributed "virtual organizations", fine-grained access control in grid computing is therefore very necessary...
The unilateral dynamic change of access policy between different domains in the grid computing platforms would incur global inconsistent privileges. To address the problem, this paper proposes a new component named coordinated negotiation policy and introduces it into authorization mechanism in the grid system. Based on the policy repository stating how to response to the change of privileges, the...
The dynamic change of users and resources would incur the overall inconsistency of the access policies between different domains in grid. This would have a bad effect on the grid operations, and compromise the grid system. To address the problem, this paper proposes an automated negotiation engine combining with the authorization mechanism. The engine can detect timely the change of access policies,...
High energy physics (HEP) experiments are facing unprecedented challenges to deal with huge volumes of data. Grid is the excellent technology for it. However, Incompatibility of a variety of grid middewares is an obstacle to exploit the resources on multiple grid infrastructures. This paper firstly introduces HEP experiments and HEP grid, and then reviews the solutions for grid interoperability and...
Peer-to-Peer (P2P) electronic commerce greatly enhances the convenience and flexibility of e-business, but it also aggravates the risk and security threatening business activity. In order to prevent the vulnerable peers from involving in transaction and solve the trust problem of no-history record peers, this paper proposes a new trust model of P2P e-commerce, which is based on voting agreement. It...
This paper proposes the use of grid computing platforms as an enabling technology for the implementation of a pervasive infrastructure which aims at improving the efficiency and effectiveness in the containment of network attacks. First, we identify a set requirements and design principles for the construction of new intrusion detection systems. Then, we present a set of grid capabilities and features...
