Abstract

The invention proposes an ultrasound-based VPN communication system, method and computer-readable storage medium. In this system, the controller pre-stores the VPN service account number and password set, dynamically changes the VPN service account number and password, and sends the VPN service account number and password to the VPN server and the ultrasonic generation module; the ultrasonic generation module sends the current service password to the first intelligent terminal and account number, the first smart terminal sends a first wireless signal containing the service account number and password to the VPN server; the VPN server refreshes the currently valid VPN service account number and password, when the currently valid service account number and password and the first wireless signal When the VPN service account and password are consistent, the VPN server and the first smart terminal establish a VPN communication connection. The system and method enhance VPN communication security, and are convenient to implement and low in cost.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and more specifically, relate to an ultrasound-based VPN communication system, method, and computer-readable storage medium. Background technique [0002] With the rapid development of Internet technology, people's daily work and study are inseparable from network information transmission, and the resulting network security issues have become increasingly prominent. In the prior art, in order to form a secure network within a specific range, each company or family builds an internal LAN, but this internal LAN has a limited distance, and remote users cannot directly access these internal networks through ordinary public networks. [0003] In order to solve the problem of remote access to the internal network, VPN (VirtualPrivateNetwork) communication technology has been proposed. By opening a dedicated virtual information transmission channel for users in t...
