All, We, at IBM T.J.Watson Research Center, have been developing a policy analysis module on top of Imperius that allows a policy writer perform the following tasks automatically. 1) Dominance check: finding if a policy is dominated by other policies, thus removing redundancy among policies. 2) Simultaneous applicability check: finding if two policies are simultaneously applicable, thus preventing potential conflicts at specification time. 3) Coverage check: finding if a set of policies covers all the sensor spaces required, thus ensuring policies specified adequately. 4) Meta policy based conflict detection/resolution: detecting/resolving conflicts at runtime. 4) Rule-based policy transformation: allowing transformation of abstract policy into concrete policies or vice versa. The package implements advanced algorithms for policy analysis and requires certain changes to be made to the current Imperius implementation for integration. We would like to find out if there is a strong interest in this effort and possible integration with Imperius.
