Audited credential delegation: a usable security solution for the virtual physiological human toolkit

<20> Professor Abdallah and Dr Haidar (his ex PhD student) are the main security experts contributing to this research. They were the principle designer of the security architecture deployed in the user- friendly Application Hosting Environment (AHE) to run computational e-science applications on grid resources. The Audited Credential Delegation (ACD) security solution described in this paper was specifically designed to overcome usability issues encountered in other existing tools such as Globus, Unicore, and AHE. Prof. Abdallah’s work with Dr Haidar on parameterised role based access control and on designing security controls (authentication, authorization and auditing) as software wrappers are the basis for the implementation of the system. This toolkit has been used worldwide by several e-science groups including partners in the current EU project on Virtual Physiological Human. This work was supported by a £340K EPSRC project in which Prof. Abdallah was an investigator.
