We show that the expressive powers are incomparable between any pair of history-based access control, regular stack inspection and shallow history automata. Based on these results, we introduce an extension of HBAC, of which expressive power exceeds that of regular stack inspection.}, pages = {1033--1036}, title = {Comparison of the Expressive Power of Language-Based Access Control Models}, volume = {E92-D}, year = {2009} }
