A Static ABAC Policy Conflict Resolution Algorithm

This paper discusses policy conflict resolution for attribute-based access control in the distributed computing environment, proposes a conflict resolution algorithm based on policy condition attribute significance. The algorithm evaluates policy condition attribute significance by using Bayesian formula and conditional probability formula through policy condition attributes usage record, gets the key policy condition attribute which influences policy decision attributes, resolves policy conflict by the achieved key policy condition attributes. Finally, performance of the algorithm is experimented and analyzed.
