Problems solved by technology

[0005] The embodiment of the present invention provides a method and device for identifying Skype-based communication streams with different functions, which is used to solve the problem that the existing identification technology cannot identify highly coupled traffic in the Skype functional communication streams, so it is impossible to identify Skype's single Function identification, resulting in the inability to perform fine-grained current limiting for common Skype functions

Embodiment 1

[0053] Embodiment 1 of the present invention provides a method for identifying communication streams based on different functions of Skype, such as figure 1 As shown, it is a schematic flow chart of the identification method based on Skype different function communication streams described in Embodiment 1 of the present invention, and the method may include the following steps:

[0054] Step 101: Obtain the transmitted packets in the current session.

[0055] Step 102: Perform a preliminary detection on the transmission message, if the transmission message is accurately identified, mark the current session with a corresponding function application label; if the transmission message is not accurately identified, determine The detection level to which the transmission message belongs.

[0056] Step 103: Detect the transmission message according to the detection rule corresponding to the detection level to which the transmission message belongs, and when the detection condition ...

Embodiment 2

[0109] Based on the same inventive concept as that of Embodiment 1 of the present invention, Embodiment 2 of the present invention provides an identification device based on Skype communication streams with different functions. For the specific implementation of the identification device, please refer to the relevant description in Embodiment 1 of the above-mentioned method. Repeated points will not be repeated. Specifically, such as image 3 As shown, it is a structural schematic diagram of the identification device based on Skype different function communication flow, and the identification device based on Skype different function communication flow may specifically include:

[0110] The acquisition unit 31 can be used to acquire the transmission message in the current session;

[0111] The processing unit 32 is configured to perform preliminary detection on the transmission message acquired by the acquisition unit 31, and if the transmission message is accurately identifie...

Abstract

The invention discloses a method and device for identifying communication streams based on different functions of Skype. The method includes acquiring transmission messages in the current session, and performing preliminary detection on the transmission messages. If the transmission messages are accurately identified , then mark the current session with the corresponding function application label, otherwise determine the detection level to which the transmission message belongs, and detect the transmission message according to the detection rule corresponding to the detection level to which the transmission message belongs Performing detection, and marking the current session with a function application label corresponding to the detection level to which the transmission message belongs when the detection condition is met. That is to say, in the present invention, the problem of indistinguishable coupled traffic is solved through incremental identification, so that a single function of Skype can be identified, and refined access control on Skype traffic can be completed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for identifying communication streams based on different functions of Skype. Background technique [0002] Skype is one of the most popular instant messaging software in the world. It can be used for free and clear voice conversations with other users, and it can also make domestic and international calls. Skype mainly uses the p2p network architecture and private protocol communication, and also performs strong encryption on the data, and the communication process of Skype is very complicated, and the code volume is also very large, so it is difficult to analyze the source code through reverse work, so that until now So far, the identification of Skype is still in the simple identification stage. [0003] For example, the existing recognition technology can restrict the use of all functions of Skype by identifying the login process of Skype, or identi...
