摘要：
Role-based access control (RBAC) models have received broad support as a generalized approach to access control. However, there are requirements to limit the maximum number of usage times of roles assigned to users, that cannot be modeled under current RBAC models. We present UC-RBAC model, an extended RBAC model, to tackle such dynamic aspects. UC-RBAC supports such constraints during periodic time. The constraints can be set to limit the usage of a role of both a specified user and all users assigned to the role. The formal definition and semantics of the model are presented.
