目前现有的大多数门限签名方案其门限值是固定的,在实际应用中,往往希望能根据被签名消息的重要性动态改变门限值.针对现有动态门限签名方案存在的不足,提出了一个基于双线性对的动态门限签名方案.同时,对方案的安全性进行了分析,结果表明本方案是一个安全、有效的动态门限签名方案.
目前現有的大多數門限籤名方案其門限值是固定的,在實際應用中,往往希望能根據被籤名消息的重要性動態改變門限值.針對現有動態門限籤名方案存在的不足,提齣瞭一箇基于雙線性對的動態門限籤名方案.同時,對方案的安全性進行瞭分析,結果錶明本方案是一箇安全、有效的動態門限籤名方案.

The threshold value of the most available threshold signature schemes is fixed. However, in many occasions, it is ideal to dynamically change the threshold value according to the significance of the message. A dynamic threshold signature scheme from bilinear pairings was presented to solve the problem in the available dynamic threshold signature scheme. The security of the scheme was also analyzed. It is shown that the proposed scheme is secure and effective.
