Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] like figure 1 As shown, the WiFi authentication method based on the dynamic password of the embodiment of the present invention comprises the following steps:

[0034] In the first step, the mobile terminal registers on the server;

[0035] In the second step, the wireless access point (AP) needs to register on the authentication server and submit relevant information (such as Mac address, IP address, initial password, geographic location information, etc.);

[0036] In the thi...

Abstract

The invention discloses a WiFi authentication system and method based on a dynamic password. A mobile terminal is arranged. The mobile terminal registers on a server; a wireless access point registers on an authentication server and submits relevant information; the wireless access point manages an authority to access or not access the network of the mobile terminal; the server sends a WiFi password to the mobile terminal of a legal user in an encryption manner; the mobile terminal passes Wi-Fi protected access pre-shared key (WPA PSK) authentication and accesses the network; 24 hours later, the wireless access point randomly generates a new strong password and submits the strong password to the authentication server; the server sends the new WiFi password to a legal user of the system in the encryption manner; and the mobile terminal of the legal user passes WPA PSK authentication and accesses the network. Through adoption of the system and method, problems of weak passwords and password leakage by insiders are solved, the digital dynamic password of very high security is adopted, and the password is updated and authenticated automatically, so that human factors are furthest reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless networks, and in particular relates to a dynamic password-based WiFi authentication system and method. Background technique [0002] Wi-Fi is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as pads and mobile phones) to each other. In fact, it is a high-frequency radio signal. Wi-Fi is a brand of wireless network communication technology, held by the Wi-Fi Alliance. The purpose is to improve the interoperability between wireless network products based on the IEEE 802.11 standard. Wireless network refers to "wireless compatibility certification" in the category of wireless local area network, which is essentially a commercial certification and also a wireless networking technology. In the past, computers were connected through network cables, while Wi-Fi is connected through radio waves. The common one is a wireless router, so the effectiv...
