Identity-based Broadcast Encryption with Privacy Guarantee
In many broadcast encryption environment it is important to protect both encrypted messages and the identities of authorized users. But most of current identity-based broadcast encryption (IBBE) systems fail to protect the privacy of their users. In this paper, we propose the formal definition of privacy guarantee in the IBBE. Then, we give the first IBBE scheme that is adaptively secure and privacy guaranteed in the standard model.
