Abstract
We aim to efficiently design a unified, cost-effective primitive exhibiting two mutually orthogonal functionalities, namely subscribed users anonymity and public-key traitor traceability in the context of Broadcast Encryption (BE), and propose an explicit construction of identity-based Fully Anonymous Public-Key Trace and Revoke (FAnoPKTR) scheme that is obtained by coupling the Identity-Based Encryption (IBE) framework with the collusion-secure optimal probabilistic fingerprinting codes. In addition to being adaptively secure, our design is proven to be INDistinguishable Chosen-Ciphertext Attack (IND-CCA) secure under asymmetric Decisional Bilinear Diffie-Hellman Type-3 (DBDH-3) assumption in standard security model without random oracles. Our asymmetric Type-3 bilinear pairing-based scheme has communication bandwidth that grows with the size of a subscriber set for any encryption, and the user secret-key size is constant. Moreover, our decryption algorithm is faster, which requires only three asymmetric pairings to recover the encrypted broadcast message.
