Signaling transmission encryption and decryption method, device and terminal

Abstract

The invention discloses a signaling transmission encryption method, a signaling transmission encryption device, a signaling transmission decryption method, a signaling transmission decryption device and a terminal. The encryption method comprises the steps of sending request information to a first quantum secret key machine; receiving a quantum secret key index number from the first quantum secretkey machine, wherein the quantum secret key index number is generated by the first quantum secret key machine according to the request information; acquiring a quantum encrypted secret key from the first quantum secret key machine according to the quantum secret key index number; using the quantum secret key to encrypt a communication protocol to be sent; and generating a quantum encrypted identifier header, wherein the quantum encrypted identifier header comprises a quantum encrypted identifier, a current call CallID and the quantum secret key index number; acquiring encrypted data by usingthe quantum encrypted identifier header and the encrypted communication protocol to be sent; and sending the encrypted data to a called terminal. According to the methods, devices and terminal provided by the invention, the protocol signaling data is encrypted in a quantum encrypting manner, and the security level of the conference communication is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a signaling transmission encryption and decryption method, device, terminal and computer-readable storage medium. Background technique [0002] At present, the main users of video conferencing systems are concentrated in key industries such as the government, military, telecommunications, energy media, and large and medium-sized enterprises. According to national requirements, its "information security level protection" should reach level three or above. [0003] There are security risks in the video conferencing system, which mainly come from: security loopholes in the system itself, attackers can use system loopholes to obtain conference information; hacker intrusion, mainstream video conferencing uses protocols such as H. Make it easier for hackers to attack the system; steal transmission tunnels and network routes, use equipment with "backdoors", which are easy...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the embodiment of the present invention provides a signaling transmission encryption and decryption method and device to solve the problem that the encryption method of the video conference in the prior art still makes the data transmission of the video conference system a potential safety hazard
