| 摘 要： | 早先的一种具有追踪性的门限签名方案，已被证明不具有可追踪性。针对该方案存在的缺陷，对其进行改进。理论分析证明，改进的方案在发生纠纷时可打开群签名追踪实际签名者，签名者能证明自己是否参与签名，并有效抵御群体内部的伪造攻击和冒充攻击。

| Abstract: | It is proved that an early traceable threshold signature scheme hasn't the property of traceability.Aiming at the weakness,this paper proposes an improvement to the scheme.Theoratical analysis proves actual signers can be revealed by trusted center to open group signature and also can prove if they join in the signature or not,efficiently prevents forgery attacks and masquerade attacks from inner members of group effectively. |

| Keywords: | traceable threshold signature forgery attack security |
