Practical Attribute-Based Encryption: Traitor Tracing, Revocation, and Large Universe
... In this paper, we proposed the first practical CP-ABE and KP-ABE that simultaneously support (1) traitor tracing, (2) revocation and (3) large universe. Both schemes are highly expressive in supporting any ...
