摘要
可信中心在数字签名、认证、识别等信息安全领域具有重要的作用。然而已有基于门限(k,n)签名的研究要么使用单一可信中心,要么使用n个可信中心,这两种可信中心都给应用带来不便,为此,提出一个分布式可信中心的门限盲签名方案。分析表明,该方案易于实现,安全性更高,能够满足电子群签名的需要。
The TP(trusted party) is a very important role in information security,such as signature,authentication,and identification.But the existed research based on threshold(k,n) signature was shortage by using single TP or n TP.A signature scheme of threshold and blindness based on distribution trusted party was put forward.The scheme is easier to carry out and safer.It is adequate to electronic signature in the security of system.
