Abstract: A new anonymous communication scheme using the threshold cryptosystem to improve anonymity and security against attacks is proposed.For the receiver server，the scheme completes the secret share distribution management as soon as selecting reasonable routing.These secret shares with anonymity are stored step by step.If the identity and quantity of senders are confirmed，the receiver server implements the identity resuming and offers the relevant statistic.Simulation results show that the proposed scheme provides both higher reliability and security than traditional protocols of anonymous communication.

摘要： 基于门限密码体制设计了具有较强匿名性和抗攻击的匿名通信方案。该方案在完成匿名通信合理选择路由的同时，也完成了接收方秘密份额的分配管理；经过匿名传送到接收方服务器的秘密份额将分步存储；在确认发送终端身份和数量时，由接收方服务器完成对其身份的恢复和统计。经过实验分析，该方案比传统的匿名通信协议提高了系统通信性能和抗攻击能力。
