Embodiment Construction

[0044] Basic embodiments of the invention will be described in detail below with reference to the accompanying drawings, examples of which are shown. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0045] The invention is a realization method of an end-to-end voice encryption system based on 3G / B3G, which mainly includes processes such as user registration, call and communication, and communication cancellation, including key management functions.

[0046] After obtaining the ability to access the packet network, various terminals initiate registration with the CMS, and the CMS records the current user's IP address and port number, and registers its status. After registration, encrypted communication requests to registered users can be initiated at any time. At the same time, the registered terminal regularly sends a status message to the CMS, including the user ID, etc., so that the CMS considers the us...

Abstract

The invention provides a realization method of end-to-end voice encryption system based on 3G / B3G. A mobile encryption terminal is accessed into a grouping network through 3G / B3G, and launches registration to a communication management server (CMS); after the registration is finished, a terminal user can launch a calling request to the registered legal user; a calling party sends a calling request to the CMS; the CMS sends a communication working key request to a key management center (KMC); the KMC encrypts and packages the working key and sends to the CMS; the CMS can perform direct communication according to the communication capacity of two parties of the communication, or performs transit communication; no matter in which manner, the calling party and the called party perform mutual authentication, and receive the working key distributed by the KMC, thus the two-party encryption realizes end-to-end voice communication. The corresponding system for providing the encryption service comprises a mobile encryption terminal, a content management system (CMS) and the KMC. By utilizing the whole set of system, the end-to-end encryption voice communication can be realized.

Description

technical field [0001] The present invention relates to the field of communication, especially the end-to-end encryption communication method and related system between mobile terminals, between mobile terminals and computers, and between mobile terminals and fixed broadband network IP equipment in wireless communication fields such as 3G / B3G networks. Background technique [0002] With the rapid development of communication technology, the world is entering the information age. In the 3G / B3G network, in addition to traditional voice services, it also provides multimedia services, data services, e-commerce, Internet services and other information services. A large amount of information is transmitted on the communication network every day, including a large amount of sensitive information related to politics, economy, finance and people's life. At present, the transmission of traditional voice data in the mobile communication network is basically unencrypted. This is becaus...
