Media data transmission system, method and device, and storage medium

Abstract

The invention relates to a media data transmission system, method and device, and a storage medium, and belongs to the technical field of communications. The system comprises a sending end for acquiring an encryption key and a key identification of the encryption key according to a dynamic key strategy, encrypting media data to be sent according to the encryption key to acquire encrypted media data, encapsulating the encrypted media data and the key identification by using an extended media transmission protocol to acquire a media data packet, and sending the media data packet to a receiving end through a media transmission channel; and the receiving end for acquiring the key identification in the media data packet, acquiring a decryption key corresponding to the encryption key according to the key identification, and decrypting the encrypted media data in the media data packet according to the decryption key to acquire the media data. The technical problem that a video conference is required to be interrupted in need of replacement of the encryption key can be solved; the continuity of a session can be improved; and the key updating efficiency is improved.

Description

technical field

[0001] The application relates to a media data transmission system, method, device and storage medium, and belongs to the technical field of communication. Background technique

[0002] With the development of communication technologies, users in different regions can conduct video conferences through video conference terminals.

[0003] During the video conference, the sending end uses the pre-acquired encryption key to encrypt the video data to be sent; correspondingly, the decryption end uses the pre-acquired decryption key to decrypt the encrypted video data, and obtains the video data.

[0004] However, during the course of a video conference, the encryption key and decryption key are fixed; if the users participating in the conference need to change the key, they need to stop the video conference and obtain the key again, and then restart a video conference. At this time, it will cause the problem that the video conference is interrupted. Contents ...
