一个安全有效的门限签名方案

A Secure and Efficient Threshold Signature Scheme

文章通过引入秘密分享成员的身份代码附加参数,构造了一个可以阻止恶意成员数大于门限值时进行伪造签名的门限数字签名方案,此方案的安全性是基于在特定条件下求解二次剩余的困难性。并讨论了该方案的有效性和安全性。

A secure and efficient threshold signature scheme is set up in this paper.Since we have introduced an identity code parameter that can be used to hold off the forge signature of malicious shareholders,when the number of them is more than the threshold.Its security is based on the difficult of solving quadratic residue on some special conditions.The security and efficiency are also discussed.
