Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] Such as figure 1 As shown, in the embodiment of the feature matching method and slave module based on the master-slave cooperative processing mode of the present invention, the feature matching method includes the following steps:
[0031] Step S11 main control module assigns an initial value to its counter by the data transmission counting unit connected on its general interface, and is configured into an initialization state; The module is a feature matching hardware structure. The feature matching structure is a slave device and is in a passive working mode. The main control module is responsible for initializing it, inputting matching data, starting the matching operation, retrieving the matching result, and ending it. In this step, the main control module first sends the initial value content and state of the counter to be configured throug...

The invention relates to a master-slave coprocessing mode-based characteristic matching method used for a system or equipment comprising a master control module and a slave module. The method comprises the following steps that: the master control module controls the initiation of the slave module connected therewith through a universal interface of the master control module; the master control module transmits a data packet required to be detected to the slave module, and controls the slave module to perform characteristic matching on the data packet; and the master control module controls the slave module to return a matching result. The invention also discloses a slave module using the characteristic matching method. The master-slave coprocessing mode-based characteristic matching method and the slave module have the advantages that: hardware is used in a matching mode, so the requirement on high-speed matching is met; and simultaneously, the slave module is controlled by the master control module and transmits information through the universal interface of the master control module, and the design difficulty and use requirement are reduced, so the slave module is easy to promote and apply.
Description
technical field [0001] The present invention relates to the field of network security, more specifically, to a feature matching method based on a master-slave collaborative processing mode and a slave module Background technique [0002] Deep packet inspection technology is an important technological change in the field of network security and the core technology of network content security. The core link of deep packet inspection technology is to use feature matching technology to detect whether a predefined pattern appears in the packet payload. Pattern Matching refers to the operation of finding one or all occurrences of "Pattern" in "Text String" (Text), and the length of "Text String" is greater than or equal to the length of "Pattern". High-speed feature matching technology plays a vital role in improving the performance of network security systems. With the rapid growth of network bandwidth exceeding Moore's Law, software algorithms based on general-purpose processo...
