    Advanced security infrastructures for grid education
    Sinnott, R. O. ; Stell, A. J. ; Watt, J. P. ( 2006)
    This paper describes the research conducted into advanced authorization infrastructures at the National e-Science Centre (NeSC) at the University of Glasgow and their application to support a teaching environment as part of the Dynamic Virtual Organisations in e-Science Education (DyVOSE) project. We outline the lessons learnt in teaching Grid computing and rolling out the associated security authorisation infrastructures, and describe our plans for a future, extended security infrastructure for dynamic establishment of inter-institutional virtual organisations (VO) in the education domain.

    Portal-based access to advanced security infrastructures
    Watt, J. ; Sinnott, R. O. ; Doherty, T. ; JIANG, J. (National e-Science Centre, University of Glasgow, 2008)
    Security and scalable user management is one of the key challenges facing the e-Research community. The very nature of deploying new Gridenabled services involves the adoption of robust and highly complex underlying technologies such as PKIs. When used correctly, these tools allow many problems in the security domain to be tackled effectively, however in the hands of the inexperienced user, the complexities of building and using these technologies can expose the system to the same weaknesses that the system is trying to mitigate.

    Dynamic privilege management infrastructures utilising secure attribute exchange
    Watt, J. ; Sinnott, R. O. ; Stell, A. J. (Engineering and Physical Sciences Research Council, 2005)
    Technologies which implement dynamic privilege management infrastructures will be crucial to the secure sharing of resources on the Grid, especially as the number of resources and participating sites increases. The DyVOSE project has successfully deployed Grid services secured with the PERMIS authorisation software implementing a static Privilege Management Infrastructure (PMI) model. The second stage of this project focuses on the extension of the current PERMIS infrastructure to include dynamic delegation of authority and cross-certification of institutional security policies. This paper describes the existing static PMI that has been used within the Grid Computing module as part of the advanced MSc at Glasgow University. We also outline an e-Science education use case that will be used to highlight how dynamic PMIs can be established using an extended version of PERMIS and utilising the Internet2 Shibboleth software to transfer user attributes and authentication tokens across institutional boundaries. This work addresses one of the key challenges in the Grid, supporting the dynamic establishment of secure Virtual Organisations (VOs).
