Embodiment Construction

[0069] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0070] In order to clearly illustrate the embodiment of the present invention, the DNS hijacking and VPN related technologies are briefly introduced below.

[0071] 1) DNS hijacking:

[0072] A domain name server (Domain Name Sever, DNS) is used to resolve domain names into network addresses, that is, IP addresses. For each network end in the Internet, there is a unique IP address for communication, just as everyone has an address for receiving mail. In an IPv4 network, the form of the IP address is 192.168.1.1; in an IPv6 netw...

Abstract

The invention provides a safety communication method and device based on a wireless local area network and electronic equipment, wherein the method comprises the steps of identifying whether a connected wireless local area network has a safety risk or not; if the wireless local area network has the safety risk, according to a preset network address of a security domain name server DNS, establishing a virtual private network VPN connection for communicating with the security DNS; and performing a domain name resolution communication process by adopting the VPN connection. According to the method, the VPN connection is not required to be established for all the wireless local area networks, and the VPN connection is only established for the wireless local area network with the safety risk; the DNS request is directed to a safe DNS through the VPN, so that a DNS hijack is prevented and the network safety is protected; meanwhile, due to the fact that the pertinence is high, the cruising ability of the electronic equipment can be improved. In addition, due to the fact that the IP address and the domain name are encrypted and transmitted through the VPN technology, network access behavior leakage of a user can be prevented.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a secure communication method, device and electronic equipment based on a wireless local area network. Background technique [0002] With the popularity of terminal equipment and the high cost of 2G, 3G, and 4G networks charged by traffic, users have higher and higher requirements for wireless network coverage. Wireless LAN, such as Wi-Fi, has become a necessary network environment in users' daily life. [0003] Currently, a user can search for a nearby wireless local area network through a Wi-Fi module on the electronic device, and when the user knows the password of the wireless local area network, the electronic device can connect to the wireless local area network. Since the user does not know whether the wireless local area network has a security risk, when the electronic device is connected to the wireless local area network, it may cause problems such as ...
