Embodiment Construction

[0071] According to the above technical solutions, the present invention will be described in detail below in conjunction with the examples.

[0072] Four types of different application software, P2P, instant messaging (IM), online game, and stock information, are selected as protocol analysis objects, and how to use the description method described in the present invention to describe protocol features is shown. Among the four types of software, the P2P category chooses Vagaa, which has a broad domestic user base, for analysis, and the version is 2.6.6.3; the IM category chooses MSN, the most widely used domestic and foreign software, for analysis, and the version is 2009 (version 14.0.8050.1202); considering online games The class is similar to the stock information class, but the function is different. This invention only selects the online game Counter-Strike software for analysis, and the version is 1.6v3647.

Abstract

The invention relates to a method for describing characteristics of a communication protocol of application software, and belongs to the technical field of information and network security. The premise of using the method is that the characteristics of the communication protocol of the application software required to be identified have been acquired in a network data packet through analysis; and then the method provided by the invention is used to describe the characteristics of the communication protocol of the application software so as to accurately identify the communication protocol of the application software. The characteristics of the communication protocol of the application software are definitely classified and defined, and the method has the characteristics of strict logic, compact structure, wide application range, good expandability and the like. When the method is used for identifying the characteristics of the communication protocol of the application software, the method has the advantages to high efficiency, accuracy, real time, expandability and the like.

Description

technical field [0001] The invention relates to a description method of application software communication protocol features, belonging to the technical field of network information security. It is suitable for describing the characteristics of application software communication protocols in the process of network data traffic identification. Background technique [0002] With the sharp increase in the number of application software used for information transmission on the Internet, users' requirements for identifying the application software are also increasing. For example: enterprises hope to identify peer-to-peer (P2P) download software, online games, stock information, instant messaging and other software that are not related to work, and then regulate employees' online behavior by disabling these software; parents of teenagers hope that Internet services Providers (ISPs) can accurately identify online game software and provide services that can prohibit the communicat...
