ID-Based Ring Authenticated Encryption
Tianjie Cao, Dongdai Lin, Rui Xue · 2005
Ring authenticated encryption has the following security requirements: semantic-security, recipient-designation, verification-dependence, verification-convertibility, recipient-ambiguity, recipient-verifiability, signer-ambiguity and signer-verifiability. Ring authenticated encryption can be used to enhance user privacy. In this paper, based on Boneh and Frankliny's ID-based encryption scheme and Zhang and Kim's ID-based ring signature scheme, we propose an ID-based ring authenticated encryption scheme. We also show that the proposed scheme satisfies the correctness property and all security requirements.
