A method and system for encrypting, hiding and discovering wifi access points

Abstract

The present invention discloses a method and system for WIFI access point encryption hiding and discovery, the method is: A. generating a first public key and a first private key, the first public key is set in the AP, and the first private key is Set in STA; B. Generate a second public key and a second private key, add the second public key to the management frame, encrypt the frame body with the first public key, and send it to STA; C, STA use the first private key to decrypt This encryption is used to discover the AP and save the second public key; D, STA uses the second public key to send subsequent management frames to the AP, and the AP uses the second private key to decrypt the subsequent management frames; the AP uses the first public key to send subsequent management frames to the AP STA. The STA uses the first private key to decrypt the received subsequent management frame. The invention utilizes an asymmetric encryption algorithm to encrypt the STA and AP management frames. Only when the STA has the correct key to decrypt the management frame can it discover the existence of the AP, thereby hiding the visibility of unauthorized users to the AP and reducing the risk of AP theft.

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 ...
