| 摘 要： | 提出一个改进的无可信中心的(t,n)门限签名方案,并进行了正确性证明,最后分析了其安全性能.新方案的安全性依赖于椭圆曲线上离散对数的分解难度和椭圆曲线数字签名方案的安全性,且该方案能够抵抗合谋攻击.

| Abstract: | A(t,n)-Threshold signature scheme without a trust party based on the elliptic curve was presented,and the correctness and the security analysis were given.The Analyses show that this scheme could resist conspiracy attack.This was scheme based on improved ECDSA,and its security depended on the elliptic curve discrete logarithm and ECDSA security. |
