中文摘要：
将公钥自认证的概念引入门限签名,提出了一种公钥自认证的(t,n)门限签名方案.该方案实现了门限签名,并且能在验证个人签名(或群签名)有效性的过程中通过一个逻辑单步同时对个人公钥(或群公钥)的真实性进行自认证,而不需认证机构颁发额外的公钥证书.分析表明,所提出的方案能够抵抗泄密、共谋、伪造和假冒等主动攻击.
英文摘要：
The concept of self-certified public keys was introduced in threshold signature.Self-certified public keys-based(t,n) threshold signature scheme based on was proposed,in which any t or more members in the group could cooperate with each other to generate a valid group signature,and the authentication of the self-certified member/group public keys can be confirmed simultaneously with a logically single step in the procedure of verifying the member/group signature.This scheme was secure against active attacks...
