Non-monotonic Practical ABE with Direct Revocation, Blackbox Traceability, and a Large Attribute Universe

Dirk Thatmann

Abstract

This work shows all necessary calculations to extend the ``Practical Attribute Based Encryption: Traitor Tracing, Revocation, and Large Universe'' scheme of Liu and Wong with non-monotonic access structures. We ensure that the blackbox traceability property is preserved.
