IP telephone terminal and safety communication method thereof

Abstract

The invention discloses a method for the safe communication of the IP telephone terminal, comprising: starting the fire wall, the fire wall is assembled in the safe fire wall module of the IP telephone terminal; receiving the data messages from the IP network; the fire wall monitors and analyzes the received data messages to identify the legal data messages and filter and shield the illegal data messages. The invention also discloses an IP telephone terminal. The invention has the advantages of solving the problems of the safety aspects of the IP telephone terminal, ensuring the IP telephone terminal not to be destroyed and attacked by the malicious behaviors of the virus, improving the reliability and safety of the IP telephone terminal without the support of the operating system and reducing the cost.

Description

technical field [0001] The invention relates to IP communication technology, in particular to an IP phone terminal and a method for secure communication thereof. Background technique [0002] With the continuous development of IP communication, more and more users start to use IP-based voice transmission (VOIP, Voice Over IP) system, IP private branch exchange (IP-PBX, IP-Private BranchExchange) and various IP terminals, For example, Session Initiation Protocol (SIP, Session Initiation Protocol) phones and the like have also become rich and mature. The subsequent security issues are what users are most worried about. Deception, eavesdropping, and attacks on VOIP systems are increasing, posing a great threat to users' commercial secrets and privacy. On the one hand, the security of the VOIP system needs to be strictly controlled on the server side, and on the other hand, it is also necessary to take security precautions on the IP phone terminal. If the phone terminal based ...

AI Technical Summary

Problems solved by technology

[0003] Existing IP phones, such as SIP phones, have large security holes because they have no security checks for signaling and media streams, and do not have previous analysis and control functions such as firewalls;

[0004] And on some IP phone terminals, because of its functions such as operating systems such as Windows, can transplant the firewall function on the PC to these IP phone terminals, but in the process of realizing the present invention, the inventor finds that in the prior art There are at least the following problems: IP phone terminals need the support of the operating system, the cost is high, and they cannot be widely used
