    Experiences of applying advanced grid authorisation infrastructures
    Sinnott, R. O. ; Stell, A. J. ; Chadwick, D. W. ; Otenko, O. (Springer, 2005)
    The widespread acceptance and uptake of Grid technology can only be achieved if it can be ensured that the security mechanisms needed to support Grid based collaborations are at least as strong as local security mechanisms. The predominant way in which security is currently addressed in the Grid community is through Public Key Infrastructures (PKI) to support authentication. Whilst PKIs address user identity issues, authentication does not provide fine grained control over what users are allowed to do on remote resources (authorisation). The Grid community have put forward numerous software proposals for authorisation infrastructures such as AKENTI [1], CAS [2], CARDEA [3], GSI [4], PERMIS [5,6,7] and VOMS [8,9]. It is clear that for the foreseeable future a collection of solutions will be the norm. To address this, the Global Grid Forum (GGF) have proposed a generic SAML based authorisation API which in principle should allow for fine grained control for authorised access to any Grid service. Experiences in applying and stress testing this API from a variety of different application domains are essential to give insight into the practical aspects of large scale usage of authorisation infrastructures. This paper presents experiences from the DTI funded BRIDGES project [10] and the JISC funded DyVOSE project [11] in using this API with Globus version 3.3 [12] and the PERMIS authorisation infrastructure.

    Development of a grid infrastructure for functional genomics
    Sinnott, R. ; Bayer, M. ; Houghton, D. ; Berry, D. ; Ferrier, M. (Springer, 2005)
    The BRIDGES project is incrementally developing and exploring database integration over six geographically distributed research sites with the framework of a Wellcome Trust biomedical research project (the Cardiovascular Functional Genomics project) to provide a sophisticated infrastructure for bioinfomaticians. Grid technologies are being used to facilitate this integration. Key issues to be investigated in BRIDGES are data integration and data federation, security, user friendliness, access to large scale computational facilities and incorporation of existing bioinformatics software solutions, both for visualisation as well as analysis of genomic data sets. This paper outlines the initial experiences in applying Grid technologies and outlines the on-going designs put forward to address these issues.
