The invention provides an anonymous network user traceablility method based on a TCP/IP side channel. The method comprises steps that 1), a flow monitoring system is deployed at a key node; 2), flows monitored by the flow monitoring system are screened according to the anonymous network flow characteristics to acquire flows of users entering the anonymous network; the flowing-out flow of the anonymous network can be acquired through an anonymous network relay node; 3), the flows of the users entering the anonymous network and the TCP/IP protocol side channel information of the flowing-out flow of the anonymous network are both extracted; and 4), the users of the anonymous network and an accessed server of the users are associated according to the TCP/IP protocol side channel information, and anonymity is cracked. The method can be widely applied to cracking anonymous network crimes. 本发明提出种基于TCP/IP侧信道的匿名网络用户溯源方法，包括以下步骤：1)在关键节点部署流量监控系统；2)根据匿名网络流量特征对流量监控系统所监控的流量进行筛选获得进入匿名网络的用户流量；通过匿名网络中继节点获得匿名网络流出的流量；3)同时提取进入匿名网
