| 摘 要： | 对台湾学者Jinn-Ke Jan,Yuh-Min Tseng和Hung-Yu Chien提出的“一个抗合谋攻击的门限签名方案”进行分析,通过构造有效的合谋攻击,证明其虽然经过了较为复杂的处理,付出了效率上的代价,但却仍未能阻止合谋攻击,因而完全未达到设计目标.

| Abstract: | In this paper,a threshold signature scheme withstanding the conspiracy attack is analyzed.By constructing a conspiracy attack,It is proved that the scheme can't reach the aim for which the scheme is designed although complicated techniques are introduced at cost of efficiency.Otherwise,the improvements of these schemes are discussed. |
