基于SDN的匿名通信追踪模型的研究

Anonymous Communication Tracking Scheme Based on SDN

传统匿名通信追踪方法在传统网络结构下存在难以部署、复用性、扩展性差的问题,论文基于软件定义网络SDN将控制平面与数据平面相分离的架构优势,结合SDN新型架构与网络流水印技术,利用IP时间隐通道和码元扩展技术,提出一种新型匿名通信追踪模型SACT。实验结果表明,在多种网络环境下SACT具有良好的检测率和误码率,能够可靠地确认追踪双方的通信关系,同时能够较好地解决追踪部署问题,提高了匿名通信追踪的可用性。

The traditional anonymous communication tracking methods have problems of deployment,reusability and scalabil ity under the traditional network structure.In this paper,a new model of anonymous communication tracking scheme based on SDN architectural which has the advantage of separating the control plane from the data plane is proposed.It takes advantage of the SDN architecture and network watermarking technology,a nd then combined IP covert timing channels and code extension technology.The experimental results show that it has high detection rate and low bit error rate in a variety of network environments,and can reli ably confirm the communication relationship between the two parties.At the same time,it can solve the problem of the deployment of tracking devices and improve the availability of anonymous communication tracking method.
