Cloud computing, a rapidly developing information technology, has aroused the concern of the whole world. Cloud computing is Internet-based computing, whereby shared resources, software and information, are provided to computers and devices on-demand, like the electricity grid. Cloud computing is the product of the fusion of traditional computing technology and network technology like grid computing,...
We present a web-based Grid job submission system which combines open-source software components and available system services freeing developers from having to deal with Grid middleware, credential management and user authentication. Instead, a Short Lived Credential Service provides the necessary user certificates, while Grisu libraries, developed by the Australian Research Collaboration Service,...
Grid was developed and utilized on the base of the Internet. As the problems of information security taken by the openness of the Internet are getting more and more serious, the demands for security data exchange in the Grid grow day by day. In the application environment of grid service, the intermediary need to forward the message on transmission path, which exceed the point-to-point security range...
With the rapid and profound changes in computing technology, distributed computing, as an important branch of it, is becoming increasingly important, and gradually shifts from academia to specific areas of application. Currently, extensive researches on cloud computing, grid computing, large-scale E-Commerce web sites are all manifestations of a distributed system. Participating entities in a distributed...
In the last few years, peer-to-peer systems became well known to the general public by allowing fast and simple exchange of resources between users. The complexity of these systems resides in the absence of a central authority and the fact that each user can act both as a client and as a server. Thus, a need for self-regulation arises in order to guarantee that every user contributes to the system...
Desktop Grids harvest the computing power of idle desktop computers whether these are volunteer or deployed at an institution. Allowing foreign applications to run on these resources requires the sender of the application to be trusted, but trust in goodwill is never enough. An efficient solution is to provide a secure isolated execution environment ("sandbox"), which does not constrain...
We present in this paper a secure and scalable Grid-based content management system for the management of high-volume multimedia data in the domain of the publishing industry. This is achieved by leveraging on existing individual solutions, such as the Alfresco content management system, the SRM standard for building scalable solutions based on the Grid and the GridTrust services for building trustworthy...
The COMETA e-Infrastructure running in Sicily is compliant with the EGEE middleware and specifications offering a great computing power and huge storage capacity. Since its beginning one of the main goals has been to extend the adoption of Grid paradigm from the academic to business world. Several software and hardware extensions have been implemented in order to enhance the infrastructure performances;...
Base on the research of GridFTP and P2P technology, this article seeks to put forward a high-performance, reliable file transfer task scheduling model and method in Grid environment, which characterized by support for basic security mechanisms, P2SP transmission, third-party control of transmission and ability to adapt to the dynamic, heterogeneous, distributed resources. Firstly, we set forth the...
Trust management and trust negotiation are prevailing approaches for establishing trust relationship in grid-based systems across security domains and inter-domains. In this paper, we propose TTN, a combining trust management with trust negotiation mechanism which provides the authorization and access control for the Scientific Data Grid and aims to enhance the grid security. The framework takes into...
With the development of grid computing, economy models are invented and increasingly applied, however, that is under the assumption of both transaction parties are honest and trustworthy. In reality there is serious information asymmetry between the transaction participators. Information asymmetry may cause resource providers opportunistically exploit the information gap for resource consumers on...
The security of Grid is becoming a key problem for its further application. At present, many organizations of Grid are trying to solve this problem. This paper discusses the advantages of the latest technology of Grid security, analyzes the security requirements and presents the security key technology in grid.
Combined with the grid development, this article analyzed the current widespread adoption of authentication mechanisms and researched GSI program and KX.509 program in different grid environment. With the proxy idea of KX.509, using and implementing a Web-login module to build the grid authentication model in the Globus environment. The module provides the transparent user certificate generation,...
Grid security is a key issue in Grid computing and often considered one of the most challenging aspects, which consequently attracts current research to the grid authorization, an essential part of grid security. In this paper, we briefly describe the drawbacks of the ordinary grid authorization system in complex grid environments and perform a detailed analysis on several latest grid authorization...
The Italica Project is the implementation of an electronic health record system at the Italian Hospital of Buenos Aires. The present work shows the implementation of a medical signal grid repository module and its integration to the Italica Project. We also describe the architecture of that module and explain the design decisions taken for its construction. The integration to the preexisting system...
The paper presents a technical solution to issue proxy certificate for grid end users using hardware and software token in grid systems. These tokens consist of user identity certificate and keys associated with the certificate. The discussion is initiated with the adoption of current solution; MyProxy as a generator of proxy certificate and credential repository for grid systems. Ongoing efforts...
Sharing data within grid environments always results in losing control over data usage. If the shared information is medical data, this violates laws as specified in HIPAA, because access to such data must be reconstructible and needs to be tightly controlled. To comply with these regulations it must be guaranteed, that each data access and modification is recorded to produce audit trails. The provided...
A grid portal is one of the most important ways to access grid systems. The disadvantages existing in current grid portals are that they are designed for specific applications, difficult to add new applications. Besides, the security issues are not considered fully in these portals. In this paper, we proposed a user-centric and secure grid portal architecture-USGPA based on portlet. In USGPA, a security...
