摘　　要：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。a new authenticated encryption scheme is proposed based on the discrete logarithm.The scheme bearing following characteristics: any third parties can identify its signatures to realize public verifiability;it reducing the computing complexity and band-width occupation;the timestamp has been adopted which could resist the arrack of continuously serding cryptograph.
