GRID - On-demand Trust Evaluation
2006 7th IEEE ACM International Conference on Grid Computing, 2006Co-Authors: David O'callaghan, Brian CoghlanAbstract:Security is a critical factor in interoperability of grid middleware. There is an opportunity to automate the trust evaluation and accreditation process for grid certification authorities to allow continuous evaluation of their policies and practices. To assess the feasibility and usefulness of automatic evaluation of trust in CAs a trust evaluation system has been designed and a prototype implemented. The service will evaluate a CA based on its published policies and observed practices with respect to a set of rules based on the requirements from an Authentication Profile. Development and testing are ongoing and we hope to deploy a pilot system shortly.

Multi modal verification for teleservices and security applications (M2VTS)
Proceedings IEEE International Conference on Multimedia Computing and Systems, 1999Co-Authors: G. Richard, Y. Mengay, I. Guis, N. Suaudeau, J. Boudy, P. Lockwood, C. Fernandez, F. Fernandez, C. Kotropoulos, A. TefasAbstract:The paper presents the European ACTS project "M2VTS" which stands for Multi Modal Verification for Teleservices and Security Applications. The primary goal of this project is to address the issue of secured access to local and centralised services in a multimedia environment. The main objective is to extend the scope of application of network based services by adding novel and intelligent functionalities, enabled by automatic verification systems combining multimodal strategies (secured access based on speech, image or other information). The objectives of the project are also to show that limitations of individual technologies (speaker verification, frontal face Authentication, Profile identification...) can be overcome by relying on multi modal decisions (combination or fusion of these technologies).

Static evaluation of Certificate Policies for GRID PKIs interoperability
The Second International Conference on Availability Reliability and Security (ARES'07), 2007Co-Authors: M. Medina, O. Manso, J. Luna, N. Mazzocca, V. CasolaAbstract:Validating an end-entity X.509 digital certificate prior to authorizing it for using a resource into the computational grid has become a widely studied topic due to its importance for security. A more comprehensive validation process involves not only a real-time check on the credential's status, but also an evaluation of the trust level applicable to its certification authority. Nowadays policy management authorities (PMAs) gather grid CAs fulfilling a minimum set of requirements defined in an Authentication Profile thus guaranteeing a trusted interoperability environment for grid projects. Currently this is a manual process that only results in a binary decision (the CA is able to become part of the PMA or not), however in practice, different CAs offer different security levels. In this paper we present ways to apply the reference evaluation methodology (REM) to automatically obtain the security level of a CA. The described process is based on the building of a formalized policy template for grid certificate policies. This methodology has been used to evaluate the security level offered by a set of EUGridPMA's CAs; the obtained results are then conveyed to relying parties using an infrastructure composed of CertiVeR's validation service and the Open GRid Ocsp (OGRO) middleware for the Globus Toolkit 4, thus providing enough information for a comprehensive certificate validation decision
