摘　　要：应用传统的门限签名机制进行门限签名时没有考虑进行签名的节点可信验证问题,而且传统的签名策略在抵御内部攻击、外部攻击和合谋攻击方面存在着不足。文章提出了一种基于TPCM的门限群签名的方案,采用了无可信中心和门限的签名策略,该方案有利于充分利用TPCM有限的计算能力,同时具有较好的环境适应性。The traditional threshold signature does not take time to sign the trust verification of the nodes, and traditional signature strategy has defects in the respects of against internal attacks and external attacks and collusion attacks deficiencies, this article presents a threshold group signature scheme based on TPCM, and this scheme uses a threshold signature policy and has no trusted center, the scheme can be conducive to fully utilize TPCM limited computing power, the scheme also has better adaptability to the environment.
