Invisible WiFi hotspot automatic connection device and method thereof

Abstract

The present invention discloses an invisible WiFi hotspot automatic connection device and a method thereof. According to the method, hotspot equipment calculates the SSID and password of a network according to the MAC address of the equipment and system time information, an invisible WiFi network is established through a mode of not broadcasting the SSID, and the network password is periodically changed according to the change of the system time. At the same time, terminal equipment receives an invisible WiFi broadcast frame and extracts the MAC address information of the hotspot equipment, combined with the system time information, a same algorithm is used to calculate the SSID and password of the invisible WiFi network, the connection with the WiFi network is established through the mode of active access, thus the invisible secrecy function of the WiFi network and the automatic connection purpose of the terminal equipment are realized, and the problems of low usability and poor security of an existing invisible WiFi network are solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a device and method for automatically accessing a stealth WiFi hotspot. Background technique [0002] Today's wireless network is developing rapidly, and its influence has penetrated into all aspects of social life. WiFi (Wireless Fidelity, wireless compatibility certification) is favored by more and more people because of its freedom and convenience. At the same time, with the popularity of WiFi, its security issues have gradually become a research hotspot, and various methods for cracking WiFi passwords have also reduced the security of traditional WiFi network access methods. How to improve WiFi network security has become one of the problems that need to be solved urgently. [0003] In order to improve the confidentiality of the WiFi network and protect the privacy of users, it has become a common method for the hotspot device to establish a WiFi network by di...

AI Technical Summary

Problems solved by technology

At this time, the Beacon frame broadcast by the hotspot device does not carry the SSID of the established network, so the terminal device will not be able to search for the network, and needs to manually add the SSID and password for active access

[0004] Although using the above method can improve the concealment and security of the WiFi network to a certain extent, the method of manually adding the SSID and password of the WiFi network will cause the following problems: 1. The user needs to directly obtain the network information in plain text in advance. SSID and password reduce the confidentiality of the network; 2. The SSID and password of the network cannot be changed frequently, which reduces the security of the network; 3. Users do not know whether the network exists before manual access, which is a kind of blind access , which not only increases the complexity of user operations, but also reduces the ease of use of the network
