Credential-based and policy-based access control, also called trust management, is an elegant solution for access control in open decentralised systems. Existing solutions support very expressive policy languages, but suffer from usability and privacy issues. We present a light extension of Datalog-based trust management that supports both legacy authentication mechanisms and anonymous credentials. We motivate our design decisions and demonstrate the effectiveness of our language through a prototype implementation.
