基于椭圆曲线上离散对数的难解问题构造了一种非交互可公开认证协议(PVSS),设计了可公开认证的分布式秘密共享协议,进而用该二个协议作为基本工具构造出了一个简单且有效的非交互式公开可认证的完全分布式代理签名方案,该方案对参与者的数据都能进行公开认证,可防欺诈.%Based on the intractable problem of discrete logarithm in elliptic curve, we construct a non-interactive publicly verifiable protocol, design a new publicly verifiable distributed secret sharing (PVSS) protocol and a fully distributed proxy signature scheme. The new scheme preserves the merits of fully distributed proxy signature schemes and the shares of players can be publicly verified to prevent from cheating.
