匿名即时通信监控技术研究*

匿名即时通信监控技术是近几年提出的一种网络监控技术，对于追查网络非法联络和犯罪取证具有重要的意义。首先提出了一种面向多代理技术的匿名即时通信监控模型；然后论述了匿名会话检测技术、匿名通信数据库的关联规则挖掘技术、匿名通信追踪技术等匿名即时通信监控关键技术；最后给出了实验结果，并对实验中发现的问题提出了解决方案。

Study on monitoring technology for anonymous instant messenger

Monitoring Technology for Anonymous Instant Messenger was a recently proposed monitoring technology for network security, which has great significance for illegal communication tracing and network crime forensic. Aimed to anonymous instant messenger based on multi-proxy, this paper firstly presented a network monitoring model. Secondly, described the key technology on the monitoring model including anonymous session identifying, association rule mining in anonymous session database and anonymous session tracing. Finally, discussed the experiment results for monitoring model and put forward the corresponding countermeasures for the issues appeared in the experiment.
