Security authentication method for wireless network

Abstract

The invention relates to a security authentication method for a wireless network. A wireless fidelity (WiFi) server and a client are involved, and the security authentication method comprises the following steps that: a, an authentication service program is deployed in the client, and the client is connected to a public open system of the WiFi server to acquire a corresponding internet protocol (IP) address; b, according to the IP address, the client acquires and accesses an IP address of a security authentication system of the WiFi server; c, the WiFi server authenticates a client certificate; d, the client which passes the authentication establishes first security connection with the WiFi server and acquires encryption parameters; e, the client establishes a second security connection with the security authentication system of the WiFi server according to the encryption parameters; and f, the client and the WiFi server communicate and are updated through the second security connection. By the security authentication method, the client and the WiFi server can be connected easily and quickly by using a complex key and a complex encryption way; and meanwhile, the security during connecting can be guaranteed by using a method of updating the key regularly to ensure that brute force-based cracking and possibility of key leakage are avoided.

Description

technical field [0001] The invention relates to a method for security authentication, specifically a method for wireless network security authentication. Background technique [0002] WiFi (Wireless Fidelity) technology is currently a commonly used wireless network access method in homes, businesses, and many more public places. It can gradually replace Ethernet wired connections and has a good development prospect. But there are obvious security problems in the current WiFi wireless system. In the WiFi wireless system, WEP (Wired Equivalent Privacy, wired equivalent privacy) and WPA (WiFi Protected Access, WiFi network security access) systems have very weak encryption strength for keys, while in WPA2 (another WPA PSK (Pre-shared Key, pre-shared key) is used in the system and WAPI (a protocol of China's wireless LAN security mandatory standard), so if a weaker key is used, there will be cracking problems . However, if an overly complex key is used, it will be very troubl...

AI Technical Summary

Problems solved by technology

But the current WiFi wireless system has obvious security problems

In the WiFi wireless system, WEP (Wired Equivalent Privacy, wired equivalent privacy) and WPA (WiFi Protected Access, WiFi network security access) systems have very weak encryption strength for keys, while in WPA2 (another WPA PSK (Pre-shared Key, pre-shared key) is used in the system and WAPI (a protocol of China's wireless LAN security mandatory standard), so if a weaker key is used, there will be problems of being cracked

And if you use an overly complicated key, it will be very troublesome for users to enter the key when using WiFi

Therefore, in the current WiFi wireless system, there are big problems in the privacy protection and data security protection of users.
