摘 要:
基于离散对数问题和Schnorr算法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:该方案在不暴露消息明文的情况下,任何第三方都可验证签名的有效性,实现公开验证;降低了计算量和占用带宽;在签名中加入了时间戳,能够有效防止重发密文攻击.[著者文摘]

Abstract:
A new authenticated encryption scheme is proposed based on the discrete logarithm and Schnorr algoritnm. The scheme bears the following characteristics:anyone can identify its source which obtains public verifiability without disclosing any messages;it reduces the com- putting complexity and band - width;the timestamp has been adopted which can resist the attack which sends cryptograph continuously.[著者文摘]
