Abstract

Attribute-Based Encryption (ABE) scheme is an epidemic and emerging computing paradigm currently and has a broad application in the area of fine-grained access control. Combining with NAXOS transformation, we proposed a strongly secure Attribute-based Authenticated key exchange protocol, whose security proof is under the gap Bilinear Diffie-Hellman assumption in the Attribute-Based eCK(ABeCK) model.We also use group signature to achieve traceability of the user.
