提出一种新的RSA门限签名体制,具有如下性质:(1)利用知识证明构造子签名方案,从而子签名是安全的;(2)组签名的安全性是基于RSA问题及离散对数问题;(3)可以对签名者的身份进行追踪。
A new RSA threshold signature scheme is proposed, which has the following properties: (1) the sub-signature scheme is constructed by using knowledge proof, so that the sub-signature is secure; (2) the security of group signature is based on the RSA and discrete logarithm problems; (3) The identity of the signer can be tracked.
