The invention discloses a wireless local area network safety communication method, a wireless local area network safety communication system and an authentication server. The wireless local area network safety communication method comprises the following steps that: an authentication node sends an extensible authentication protocol starting message based on a local area network to a wireless access point; the authentication node receives an extensible authentication protocol authentication request message. And the authentication node sends an extensible authentication protocol authentication response message. The authentication node receives the first encrypted information. And the authentication node decrypts the first encrypted information of the authentication server by adopting the second public key of the authentication server based on the SM2 cryptographic algorithm. And the authentication node receives the second encrypted information and decrypts the second encrypted information of the authentication server by adopting a second public key of the authentication server. And when the authentication node receives the third message, the authentication node stores the third PMK key information. According to the wireless local area network secure communication method and system and the authentication server, the communication security can be improved.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless local area network security communication method and system, and an authentication server. Background technique [0002] With the rapid development and wide application of wireless networks, the information security issues in wireless communications have gradually become prominent, and have become one of the biggest obstacles to the popularization of this technology. In order to meet the increasingly higher requirements for security and reliability in the new network environment, the security standards and protocols of wireless networks are constantly being updated and enhanced, from the first WEP protocol to the subsequent WPA and 802.11i security systems, The design principles and characteristics of wireless network security technology are constantly changing. [0003] In order to meet the application requirements of seamless interconnection of all th...
