摘　　要：基于椭圆曲线自双线性映射提出一种门限签名方案,方案中签名密钥是椭圆曲线上特定挠群上的点,方案可以有效抵御合谋攻击、验证者伪造攻击和窃听攻击,具有匿名性和可追查性。此外,方案不依赖安全信道,与同类方案相比具有较突出的性能优势。A threshold signature scheme was proposed based on a self bilinear pairing algorithm in l-torsion groups of elliptic curves over finite filed. Secret shared key was a point on elliptic curve. The proposed scheme could defend conspiracy attacks, forgery attacks, snooping attacks and fulfilling anonymity as well as traceability efficiently, and the secure channel was not compulsory in this scheme. Better performance were achieved compared with similar schemes.
