This paper attempts to accurately model security requirements for computational grid environments with particular focus on authentication. We introduce the Audited Credential Delegation (ACD) architecture as a solution to some of the virtual organisations (VO) identity management usability problems. The approach uses two complementary models: one is state based, described in Z notation, and the other is event-based, expressed in the Process Algebra of Hoares Communicating Sequential Processes (CSP). The former will be used to capture the state of the VO and to model "back-end" operations on it whereas the latter will be used to model behavior, and in particular, "front-end" interactions and communications. The modelling helps to clearly and precisely understand functional and security requirements and provide a basis for verifying that the system meets its intended requirements. |
