Generic Construction of Anonymous Deniable Predicate Authentication Scheme with Revocability

摘要

We propose a syntax and security definitions of an anonymous deniable predicate authentication scheme with revocability (rADPA). This new cryptographic primitive is to attain revocation function as well as strong privacy guarantee concerning authentication. Anonymity is for privacy in the authentication protocol, while deniabil-ity is for anti-forensics after completion of the protocol. Then, we give a generic construction of our rADPA scheme. Our approach is to build-in the revocable attribute-based encryption scheme proposed by K. Yamada et al. (ESORICS2017) into the anonymous deniable predicate authentication scheme proposed by S. Yamada et al. (PKC2012). Finally, we discuss how our rADPA scheme can be instantiated by employing concrete building blocks in our generic construction.
