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 proposed network coding technology completely changes the transmission mode of traditional networks. In this paper, an anonymous communication model based on network coding (ACM-NC) is proposed based on information segmentation theory and network coding technology. Information segmentation technology combines anonymous communication The message is divided and encoded by different anonymous links, and the encoding and transmission mechanism of the forwarding network node enhances the system’s anonymity, security and confidentiality while enhancing the ability of anti-Collusion attacks.Theoretical analysis and simulation results show that ACM- NC has a strong anonymity, security, confidentiality and collusion attacks ability, and ACM-NC only the sink node can restore the source node by decoding the encoded original anonymous communication message.
