摘要
采用Shamir秘密共享方案,利用椭圆曲线离散对数难解问题的难解性,设计了一个基于椭圆曲线的(t,n)可验证的前向安全门限签名方案,分析了它的前向安全性等特点,有一定的理论和实用价值。
This paper proposed a verifiable forward security threshold signature scheme based on the elliptic curve discrete logarithm problem, which adopted Shamir secret sharing technology. Moreover it was testified that the scheme displayed the characteristics of forward security, showing a certain theoretical and practical Value.
