Method and system for encrypting, hiding and discovering of WIFI access point

Abstract

The invention discloses a method and a system for encrypting, hiding and discovering of a WIFI access point. The method comprises steps of generating a first public key and a first private key, wherein the first public key is positioned in an AP, and placing the first private key in an STA, B generating a second public key and a second private key, wherein the second public key is added into a management frame, and utilizing the first public key to encrypt the frame body which is transmitted to the STA, C using the first private key to decrypt the encryption to find the AP by the STA and storing the second public key, D using the second public key to transmit the following-up management frame to the AP by the STA, using the second private key to perform decryption on the following-up management frame by the AP, using the first public key to transmit the following- up management frame to the STA by the AP, and using the first private key to perform decryption on the received following-up management frame by the STA. The invention utilizes the asymmetric encryption algorithm to perform encryption on the STA and the AP management frame, only the STA has the correct private key to decrypt the management frame and find the existence of the AP so as to hide the visibility of the AP toward the illegal user and thus reduce the risk that the AP can be stolen.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for encrypting and hiding and discovering WIFI access points. Background technique [0002] With the development of network technology, WIFI (wireless network) technology has been widely used in various electronic devices, and WIFI terminal (STA) depends on WIFI access point (AP) to access the network. Currently used APs usually achieve the purpose of hiding APs by not sending beacon frames (beacon frames) and not responding to broadcast probe request frames (probe request frames). However, in this case, if an illegal user grabs the management frame interacted between the STA and the AP through a network analysis sniffer based on the principle of passive listening, it can still obtain the relevant information of the AP, and can further send a non- The broadcast probe request frame exposes the AP to the control of the illegal user, thus causing the AP password to be ...
