摘要： 根据具有消息认证功能的数字签名方案设计了两种新的基于离散对数问题的有序多重数字签名方案和广播多重数字签名方案。新的方案具有简单的初始化过程,在签名时具有随机性,在签字和验证方程中无须求逆,且具有消息认证功能。具有更高的实用性和安全性。

Abstract: Based on digital signature scheme with message authentication, a new sequential digital multisig-nature and a new broadcasting digital multi-signature based on DLP are proposed. The initial stage of the schemes is simple and the signatures of the schemes are random, and il needn't to find inversion at the stage of signature or the stage of verification. The schemes are highly practical and secure.
