The embodiment of the invention provides a communication fingerprint extraction method and a device. The method comprises steps: stain marking is carried out on each data group in a network data packet and the corresponding relationship between each data group in the network data packet and the marked stain markers is recorded; program instrumentation is carried out on an application program during the process during which the application program handles the network data packet so as to acquire a program state set and a stain propagation path in which each data group operates in the application program; invariant features among at least two variables are acquired in the program state set; according to the stain propagation path, at least one data group associated with the at least one variable and marked in the network data packet is acquired; and a communication fingerprint of the application program is acquired according to the invariant features and the at least one data group associated with the at least one variable and marked in the network data packet. By adopting the method and the device provided by the embodiment of the invention, the purpose of improving the communication fingerprint extraction efficiency can be improved.
Description
technical field [0001] The present invention relates to the technical field of software, and more specifically, relates to a method and device for extracting communication fingerprints. Background technique [0002] With the rapid development of Internet technology and the popularization of network applications, network communication has become one of the important basic functions of various software systems. For the consideration of management, billing and security, the network communication of various application software is distinguished. Traffic has always been an urgent need. [0003] In the prior art, the network traffic of various application software can be distinguished through the communication fingerprint of the application software. The method of extracting the communication fingerprint of the application software in the prior art is: the application layer load feature extraction based on the network traffic, and the QQ application software is used as an example ...
