摘要

流量分类在深度包检测等网络信息安全领域具有广泛应用

而协议特征的发现是流量分类中的一个重要问题。基于文本类协议的特点提出了一种准确、高效的多协议特征自动提取方法。利用网络流量中文本内容的语义特点

将流量解析成语义单位

提出了一个在语义空间上的相似性比较方法

并据此对文本类的流量进行聚类。然后合并同一类的网络流量并提取出同类流量所共有的特征。实验表明

该方法对常见文本类协议拥有超过95%的准确率

并可以实现对流量的在线学习和分类。

Abstract

Protocol inference

which discovers protocol characteristics automatically

is an important problem in traffic classification.An accurate and efficient inference method based on semantic analysis of text traffic was proposed.According to the semantic analysis

the text content of traffic to token sequences was resolved.Then the token sequences based on a similarity comparison criterion on semantic space was clustered.At last the recognition characteristics was extracted from the token sequences that belong to the same protocol.In the experiment

the precision ratio is above 95% for common protocols and the speed can meet the needs of online training and classification.
