摘　　要：网络编码技术的提出彻底改变传统网络的传输方式,本文基于信息分割理论和网络编码技术提出一种新型的匿名通信模型(anonymous communication model based on network coding,ACM-NC),信息分割技术将匿名通信消息分割后经不同的匿名链路进行编码传输;转发网络节点的编码传输机制在提高系统匿名性、安全性和保密性的同时增强了抗合谋攻击的能力.理论分析及仿真结果表明,ACM-NC具有较强的匿名性、安全性、保密性和抗合谋攻击的能力,并且ACM-NC中仅有信宿节点才能通过解码编码消息恢复信源节点的原始匿名通信消息.The Iransnfission mode of traditional network has been significantly changed by the network coding technology. This paper proposed a new anonymous communication model based on intbrmation slicing theory and network coding technology, which is ACM-NC （anonymous communication model based on network coding）. As to this ACM-NC, the messages are transmitted through different anonymous links after being sliced t）y in- thrmation slicing technology, which could effectively improve the anonymity, seeurity and confidentiality of this model as well as enhance its ability of against conspiracy attaek. The analysis approves that the ACM-NC has strong anonymity, security and confidentiality, and only the destination node can decode and restore the original anonymous commmfication messages, which is encoded and sent from the source node.
