Method and apparatus for establishing communication connection

Abstract

Embodiments of the invention disclose a method and an apparatus for establishing a communication connection, relating to the technical field of communications and being applied to devices creating a wireless local area network. The method comprises the steps of receiving an address resolution protocol (ARP) request for a second terminal sent from a first terminal; acquiring a physical address MT of the second terminal according to the network address of the second terminal and a preset ARP list included in the ARP request; and sending the physical address MT to the first terminal so as to enable the first terminal to establish the communication connection with the second terminal according to the physical address MT sent from the device. According to the method and apparatus for establishing the communication connection, data loss of the wireless local area network access terminal in communication is reduced, and the information security thereof is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for establishing a communication connection. Background technique [0002] At present, wireless local area network sharing software is usually installed on the electronic device, and when the electronic device starts the wireless local area network sharing software, other electronic devices can be connected to the electronic device. [0003] When both the first terminal and the second terminal have connected to the wireless local area network established by an electronic device, if the first terminal needs to communicate with the second terminal, the first terminal sends an ARP (Address Resolution Protocol, Address Resolution Protocol) request to the An electronic device, the electronic device broadcasts an ARP request containing the target network address, and after receiving the ARP request, the second terminal matches the target network address in the ...

Problems solved by technology

[0004] Normally, the first terminal can successfully establish a communication connection with the second terminal according to the above method, but since the first terminal sends the ARP request in broadcast mode, all other terminals connected to the above LAN can receive the ARP request. For this ARP request, if there are terminals infected with ARP viruses among the terminals connected to the above-mentioned LAN, these terminals can forge the ARP response to the above-mentioned ARP request and send the ARP response to the first terminal. In the above-mentioned forged ARP response The included physical address is not the physical address of the second terminal, so that the first terminal establishes a communication connection based on the physical address contained in the above-mentioned forged ARP response, and when subsequent communications are performed based on the communication connection, the first terminal will store its stored data It is sent to the terminal corresponding to the physical address contained in the above forged ARP response. Therefore, after the communication connection is established using the above method, it is easy to cause terminal data loss during the communication process, and the security is poor.
