一个有效的公开可验证的认证加密方案

An Efficient Authenticated Encryption Scheme with Public Verifiability

基于离散对数问题提出了一个新的安全有效的认证加密方案。该方案与其它方案相比,最显著的优点在于认证与消息恢复的分离。这样,任何人都可以认证密文,但只有真实的接收者才有能力恢复出明文。此外,该方案从计算量和通信开销来讲都是非常有效的。

This paper proposes an efficient authenticated encryption scheme based on the discrete logarithm. As the proposed scheme separates the authentication and recovery, anyone can identify its source, but only the receiver can recover the plaintext. What＇s more, the proposed scheme is also very efficient with regarding to computation costs and communication overheads.
