基于身份的环认证加密方案的改进

Improvement of ID-based ring authenticated encryption

环认证加密方案是加密方案与环签名方案的融合,具有这两种方案的优点。但通过研究发现,有的环认证加密方案不具有环签名的无条件匿名性的性质。为此提出了一个改进方案,并分析了其性质。

Ring authenticated encryption scheme can be regarded as the combination of message encryption scheme and ring signature scheme, which has both encryption and ring signature＇s priority. This paper found that the scheme didn＇t have the unconditional anonymity characteristic being including in a ring signature, so improved it.
