Problems solved by technology

Most of the existing technologies are WLAN protocol analyzers, which are commonly implemented based on software, such as AiroPeek, Ethereal, Sniffer Wireless, etc. provided by AirMagnet and WildPackets. However, in the WAPI field, the transmission medium is electromagnetic waves, and there is no wireless transmission in the prior art. The WAPI protocol analysis method and system of the present invention cannot realize the test of the WAPI protocol consistency of the wireless local area network equipment

Abstract

The invention discloses a method and a system for analyzing a WAPI protocol. The method comprises the following steps: receiving WAPI protocol message; resolving the WAPI protocol message to acquire packet information of the WAPI protocol message; judging whether the WAPI protocol message is WAPI protocol message of a WAI packet according to the packet information of the WAPI protocol message; acquiring a value of each field in the WAPI protocol message of the WAI packet; and judging whether the WAPI protocol flow in the WAPI protocol message of the WAI packet is complete according to the value of each field in the WAPI protocol message of the WAI packet. The method and the system for analyzing the WAPI protocol can meet the requirement for testing the protocol conformance for WLAN equipment. The system is convenient to use, flexible to upgrade and accurate in testing precision, and provides a good platform for protocol test of a WAPI product.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a WAPI protocol analysis method and system. Background technique [0002] Wireless LAN Authentication and Privacy Infrastructure (WAPI) is a security protocol. Like infrared, Bluetooth, GPRS, CDMAlX and other protocols, it is a wireless transmission protocol. The difference is that it is a wireless LAN A transmission protocol in (Wireless Local Area Network, WLAN), which is similar to the 802.11B transmission protocol. At present, the WAPI mechanism has been reviewed and approved by the IEEE RegistrationAuthority authorized by ISO / IEC, and the Ethernet type number (IEEE EtherTypeField) 0x88b4 for this mechanism has been assigned. [0003] With the development of WAPI technology, in addition to typical products such as wireless access points and wireless network cards, there are more and more mobile terminals that support WAPI functions, and the demand for protocol confor...
