Abstract

The invention discloses a VoLTE voice encryption communication method, terminal and system, belonging to the technical field of wireless communication. The calling terminal initiates a call, sends a verification request to the cloud secret call service management platform, and obtains the secret call ID returned by the cloud secret call service management platform; after the call is connected, the calling terminal and the called terminal play a prompt tone, Apply for the session key of this call from the key management platform to which it belongs based on the secret call identifier; based on the session key, the calling terminal and the called terminal use the media channel to synchronize the key acquisition states of the calling terminal and the called terminal, and then proceed to Encrypted voice call; when the call hangs up, both parties send an encryption end message to end the key call. The invention does not need a certificate management module, has fast calculation speed, high security, high synchronization efficiency and good user experience.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a VoLTE voice encryption communication method, terminal and system. Background technique [0002] Voice over Long Term Evolution (Voice over Long Term Evolution, VoLTE) is a voice service based on an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS), and is an IP data transmission technology. VoLTE does not require 2G / 3G network, and all services are carried on 4G network, which can achieve shorter connection waiting time and higher-quality, more natural voice and video calls. IMS itself provides a complex and relatively secure authentication and authentication mechanism, but as malicious interception becomes more and more common, VoLTE needs a special encryption mechanism to ensure its call security. [0003] There are three main problems currently facing VoLTE voice encryption and subsequent large-scale promotion: [0004] (1) Traditional VoLTE enc...
