Embodiment Construction

[0025] The present invention is applied in data communication networks, especially in 1Gbps to 40Gbps transmission networks that require high-speed detection of all content of data packets, and realizes searching for content characteristics of network L2-L7 layers and network content without affecting the original network topology structure. Functions such as diversion, access control and its processing. The invention can also be used in the field of server security, especially in the field of high-end servers that need high-speed detection of server import and export content and server internal content.

[0026] Such as figure 1 Shown is a flow chart of the data search processing method of the present invention. The method includes the following steps:

[0027] Step 11, using a first predetermined function to perform operations on the received first data with fixed-length bytes to generate a first address; the first predetermined function is determined according to the size...

Abstract

The invention relates to a method for processing data search, comprising the following steps: utilizing a first predetermined function to take a fixed-length byte from the first data and operating to generate a first address; inquiring the mark in the first address in a first memory, and when the mark is valid, utilizing a second predetermined function to take the fixed-length byte from the firstdata and operating to generate a second address; utilizing a third predetermined function to take the byte with the length same with that of a rule from the first data to generate the second data; and comparing the second data with the data information of a rule full text corresponding to the second address in a second memory so as to process data. The invention also relates to a system for processing data search, comprising a search engine, the first memory, the second memory and a third memory. Therefore, the invention greatly shortens the time of index rule while supporting multiple rules,adopts a particular tandem routing water flowing technology, and finishes high efficient process by using less resources, thus realizing high-speed search.

Description

technical field [0001] The invention relates to the fields of data processing and network security, in particular to a data search and processing method and system using multi-level screening data. Background technique [0002] With the continuous complexity of network applications and the "complexity" of security threats, future threats will extend to a higher level, and more protocols and applications need to be checked for security, and require analysis of network traffic and management of communication content , these must be subject to content-based inspection and analysis. What users need is not simple access control through ports or packet headers. Various IM and P2P applications cannot be controlled through ports, and deep content inspection must also be carried out. For example, in the access control of the HTTP protocol, the protocol allows normal use, but does not allow certain keywords and malicious messages to enter the network, which requires in-depth inspecti...
