Efficient Attribute Proofs in Anonymous Credential Using Attribute-based Cryptography

摘要

As an important property of anonymous credential, attribute proof allows user to prove the possession of attributes issued by the issuing authority anonymously. In this paper, we introduced the notation of Attribute-based signature into anonymous credential to propose an anonymous credential with constant complexity attribute proof. Compared with other constant complexity pairing based schemes, our scheme could support more types of attribute relations while the public parameter is much shorter.
