摘要随着互联网的普及程度越来越高，上网已经成为了大部分人每天必做的事。而即时通软件的出现又将这一现象放大化，QQ，MSN，fetion等当今非常的主流聊天软件越来越受到大家的青睐。然而，这些即时通软件已经打破了原来在PC端的局限，已经在手机端开始崭露头角。时至今日，手机即时通讯软件越来越多占有了市场份额，势必在手机用户中将会掀起新的市场竞争，因此，研究这些手机即时通应用的协议格式有很高的价值。64777

本文主要研究的对象选定为中国移动手机飞信。通过研究Android操作系统，开发和使用类似Sniffer的手机抓包工具，分析智能手机中的即时通飞信的通信特征和协议格式。主要研究成果如下：

1) 通过wireshark在PC端捕获飞信数据报，分析其在PC端协议的特征及协议格式。

2) 利用tcpdump工具和分析手机端飞信的协议格式，开发出独立的手机版抓包工具CaptureIt，可以对手机上的数据报进行抓包分析。

3) 通过利用tcpdump工具的使用和开发的手机抓包分析工具CaptureIt，在android系统中完成对飞信的抓包，并对其进行分析研究，与PC版飞信协议进行比较。

Abstract

With the popularity of the Internet is becoming more, the Internet has become a thing most people do daily. Messenger software to turn this phenomenon zoom the QQ, msn, fetion, today mainstream the growing chat software is up to the Seto. However, these instant messaging software has broken the limitations of the original on the PC side, began to emerge in the mobile terminal. Today, mobile instant messaging software more and more possession of the market share, it is bound to set off a new market competition in the mobile phone users will, therefore, the study of these phones Messenger application protocol format is of great value.

In this paper, the object of study is selected as China mobile phone fetion. By studying the Android operating system, the development and use of the mobile phone of a similar Sniffer capture tool for analysis of the Messenger fetion communication smartphone features and protocol format. The main results are as follows:

1) wireshark on the PC side to capture fetion data packets, analyze the characteristics of the protocols and agreements on the PC side format.

2) To use tcpdump tools and analytical mobile terminal fetion protocol format developed independent Mobile capture tool CaptureIt datagram on the phone packet capture analysis.

3) Completed in the android system through the use the tcpdump tool use and development of the mobile capture analysis tools CaptureIt capture fetion, and analyze research compared with PC version fetion agreement.
