Supporting Periodic Authorizations and Temporal Reasoning in Database Access Control
Summary: Access control with authorizations that have periodic validity intervals, auto-granting in windows and revoking on expiry. Deductive temporal rules with periodicity and order constraints infer new authorizations; establish the uniqueness of the implicit authorization set and provide an algorithm to compute the global valid set, enabling richer protection than traditional models.
