Terminal equipment, encrypted gateway and method and system for wireless network safety communication

Abstract

The invention provides terminal equipment, an encrypted gateway and a method and a system for wireless network safety communication. The method for wireless network safety communication includes: acquiring encryption communication request information transmitted by the terminal equipment when the terminal equipment is accessed to a wireless network, wherein the encryption communication request information includes a user account of a user; acquiring a first session key and a second session key corresponding to the user account according to the encryption communication request information, wherein the second session key is obtained by encrypting the first session key by a user login password corresponding to the user account; and transmitting the second session key to the terminal equipment, and using the first session key to encrypt or decrypt data messages communicated with the terminal equipment. By the aid of the terminal equipment, the encrypted gateway, the method and the system, potential safety hazard in existing wireless network communication can be effectively avoided.

Description

technical field [0001] The present invention relates to communication technology, in particular to a terminal device, an encryption gateway, a wireless network security communication method and system. Background technique [0002] With the development of wireless communication technology, more and more public places provide wireless hotspots for wireless network access to the Internet, so as to facilitate users to use their terminal devices equipped with wireless communication to access the Internet. [0003] The establishment of a wireless hotspot is very simple and inexpensive, and its provider only needs a wireless router or a modem (modem) with wireless functions to access the network. For example, many specific public places such as airports, hotels, and coffee shops provide users with free access to the Internet using WiFi APs by configuring WiFi (Wireless Fidelity) wireless access points (WiFi Access Points, referred to as: WiFi APs). When users want to surf the Int...
