Information-Based Access Control (IBAC) has been proposed as an improvement to History-Based Access Control (HBAC) model. IBAC has been shown to be more precise than HBAC which is excessively restrictive in some cases and may incorrectly prevent the execution of operations that should be executed. However the verification problem of IBAC program has not been discussed. This paper presents a formal model for IBAC programs based on the transition systems called weighted pushdown systems (WPDS). The mapping process between the IBAC original semantics and the WPDS structure is described. Moreover, the verification problem for IBAC programs is discussed. |
