    Grid technologies support collaborative e-Research typified by multiple institutions and resources seamlessly shared to tackle common research problems. The rules for collaboration and resource sharing are commonly achieved through establishment and management of virtual organizations (VOs) where policies on access and usage of resources by collaborators are defined and enforced by sites involved in the collaboration. The expression and enforcement of these rules is made through access control systems where roles/privileges are defined and associated with individuals as digitally signed attribute certificates which collaborating sites then use to authorize access to resources. Key to this approach is that the roles are assigned to the right individuals in the VO; the attribute certificates are only presented to the appropriate resources in the VO; it is transparent to the end user researchers, and finally that it is manageable for resource providers and administrators in the collaboration. In this paper, we present a security model and implementation improving the overall usability and security of resources used in Grid-based e-Research collaborations through exploitation of the Internet2 Shibboleth technology. This is explored in the context of a major new security focused project at the National e-Science Centre (NeSC) at the University of Glasgow in the nanoCMOS electronics domain

    Integrating security solutions to support nanoCMOS electronics research

    The UK Engineering and Physical Sciences Research Council (EPSRC) funded Meeting the Design Challenges of nanoCMOS Electronics (nanoCMOS) is developing a research infrastructure for collaborative electronics research across multiple institutions in the UK with especially strong industrial and commercial involvement. Unlike other domains, the electronics industry is driven by the necessity of protecting the intellectual property of the data, designs and software associated with next generation electronics devices and therefore requires fine-grained security. Similarly, the project also demands seamless access to large scale high performance compute resources for atomic scale device simulations and the capability to manage the hundreds of thousands of files and the metadata associated with these simulations. Within this context, the project has explored a wide range of authentication and authorization infrastructures facilitating compute resource access and providing fine-grained security over numerous distributed file stores and files. We conclude that no single security solution meets the needs of the project. This paper describes the experiences of applying X.509-based certificates and public key infrastructures, VOMS, PERMIS, Kerberos and the Internet2 Shibboleth technologies for nanoCMOS security. We outline how we are integrating these solutions to provide a complete end-end security framework meeting the demands of the nanoCMOS electronics domain

    Digital object rights management: Interoperable client-side DRM middleware

    Get PDF
    In a more and more interconnected world where the available bandwidths are increasing at a pace hard to imagine some time ago, multimedia e-content distribution over digital networks has become one of the biggest available services online. Powered not only by the network high availability but also by the emergence of new compression techniques and digital content consumer device, digital content is gaining momentum. However the same factors that power this emergence are also causing some problems, specially related with the digital content IPR management and protection. These problems are being handled employing DRM - Digital Rights Management technology which lack interoperability. This paper presents and discusses a solution that provides interoperability to DRM-protected content through the employment of a client-side DRM middleware layer. This middleware layer sits at the client-side of a broader DRM system (called DoRM) providing the necessary mechanisms to achieve interoperability between the different digital content rendering applications that the users possesses.info:eu-repo/semantics/acceptedVersio

    This article describes the implementation of the IPTV technology through an open source system for the wireless Internet service provider (WISP) in the Cerecita site, located in the province of Guayas, Ecuador. The feasibility of implementing the IPTV technology is given through the use of the Emby Server application, in addition to the use of an operating system such as CentOS 7, which are open source and have the necessary requirements for the creation of this service. The analysis of data tra c generated on the WISP network, which will establish the advantages and disadvantages generated by the transmission of this technology, created to VOD multimedia content server that allows the video signal to be sent to users Finally, a feasibility study was carried out to analyze the advantages and disadvantages that exist in the implementation of this IPTV technology.Este artículo describe la implementación de la tecnología IPTV a través de un sistema de código abierto para el proveedor de servicios de Internet inalámbrico (WISP) en el sitio Cerecita, ubicado en la provincia de Guayas, Ecuador.

    An alliance of Canadian Universities and government agencies pooled their resources to establish a network to share and combine Learning Objects from a variety of sources and further develop this technology. In the process, they resolved many learning, logistical, and legal problems and moved this technology forward by an order of magnitude. Principal goals include: nationwide interoperability, network of repositories, linked servers, repository software programs, national and international standards, digital rights management, business and management models, evaluation and feedback, dissemination of results, and bilingual access to all Canadians, particularly learners with disabilities. The defined tasks were sub-divided into nine work packages, each with a lead institution as package manager

    Using web-services to manage and control access to multimedia content

    In a largely interconnected World, the Web-Services (WS) computing paradigm is gaining momentum. Most Web Services applications existing today are being developed in the E-Business or E-Commerce context, mainly for Enterprise Application Integration (EAI) [12]. This paper describes a distributed architecture that largely uses WS technology to control and manage the access to multimedia content and that represents the new and emerging market of Digital Rights Management (DRM). This architecture deploys some critical DRM elements, in a service-oriented architecture, such as device and user identification and authentication, content registration and protection, license representation and production and payment. This paper presents the conceptual architecture, referred to as OpenSDRM [3], and provides some technical details about its development and deployment.info:eu-repo/semantics/acceptedVersio
