摘要： 针对传统的异常信息流检测方法的不足，设计了一种基于流量分析的网络隐蔽通道检测模型，它采用了概率统计中的泊松分布和数据挖掘中的聚类分析等方法，开辟了一条检测信息暗流的新途径。

Abstract: As the traditional methods of abnormal information stream detecting are limited too much in function, this paper produces a model based on traffic analysis, which can detect network covert channel in another way. In the model, Poisson distribution in statistics and clustering analysis in data mining are introduced.
