基于离散对数问题提出了一个新的有效的认证加密方案。新方案具有以下优点:允许任何第三方验证签名,实现公开验证;降低计算量和占用带宽;在签名中加入了时间戳,能够有效防止重发密文攻击。
Based on the discrete logarithm problem, a new effective authentication and encryption scheme is proposed. The new scheme has the following advantages: Allowing any third party to verify the signature for public verification; Reduce the amount of computation and occupancy bandwidth; Add a timestamp to the signature, which can effectively prevent the retransmission of ciphertext attacks.
