Abstract or Description

We present a constructive authorization logic where the meanings of connectives are defined by their associated inference rules. This ensures that the logical reading of access control policies expressed in the logic and their implementation coincide. We study the proof-theoretic consequences of our design including cut-elimination and two non-interference properties that allow administrators to explore the correctness of their policies by establishing that for a given policy, assertions made by certain principals will not affect the truth of assertions made by others.
