一面向组(t， n ) 阀值签名计划采用秘密份额的密码的技术，从 n 播放器允许 t 播放器的任何子集代表这个组签署消息并且如果，禁止有效签名的创造比 t，播放器参加的少数签名协议。在这篇论文，我们求婚了一新面向组(t， n ) 与可追踪的签名人一起的阀值签名计划基于 Schnorr 签名。建议计划被证明可追踪，柔韧并且对有在随机的神谕模型和广播隧道的存在的分离对数假设的“静态”的对手的 unforgeable。最强壮的安全(对在分离对数假设下面的适应地选择的消息攻击的存在 unforgeability ) 的证明在随机的神谕模型被提供。

英文摘要：

A group-oriented （t, n） threshold signature scheme employs the cryptographic techniques of secret share, allows any subset of t players out of n players to sign message on behalf of the group and disallows the creation of a valid signature if fewer than t players take part in the signature protocol. In this paper, we proposed a new group-oriented （t, n） threshold signature schemes with traceable signers based on Schnorr signature. The proposed scheme is proved traceable, robust and unforgeable against the ＂static＂ adversary with the discrete logarithm assumption in the random oracle model and existence of broadcast channel. The proofs of the strongest security （existential unforgeability against adaptively chosen message attacks under the discrete logarithm assumption） are provided in the random oracle model.
