Embodiment Construction

[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0062] It should be noted that the entire video conference encryption and decryption process can be divided into: media data collection, encryption, sending, receiving, decryption, and framing. It can be divided into two independent wholes: sending and receiving, where sending includes: media data collection, encryption, and sending; receiving includes: recei...

Abstract

The invention discloses a data encryption and decryption method, a device and an electronic device, wherein, the data encryption method comprises the following steps: a media code stream thread disassembles the collected code stream frame into a data packet to be encrypted; the encryption and decryption threads encrypt the data packets to be encrypted respectively to obtain the encrypted data packets, wherein, the encryption and decryption threads are independent of the media stream threads and the network sending threads; the network sending thread sends the encrypted data packet. The data encryption method provided by the embodiment of the invention adopts a separate encryption/decryption thread to encrypt the data packet to be encrypted, The encryption process is separated from the network transmission process, which improves the network encryption and decryption throughput in the traditional implementation, reduces the delay of the video conferencing system, realizes the high utilization of the network transmission thread and the encryption and decryption thread, and improves the utilization rate of the low-speed encryption and decryption equipment.

Description

technical field [0001] The invention relates to the technical field of video conferencing, in particular to a data encryption and decryption method, device and electronic equipment. Background technique [0002] In recent years, with the development of network technology, secure communication technology, and media technology, traditional video conferencing has also begun to pay attention to the security of code stream transmission. Generally, it is developed into a trusted video conference combined with secure communication technology to protect system security and credibility. At the same time, a variety of encryption algorithms and authentication algorithms can also be used to meet security requirements in different conference scenarios. [0003] In the process of migrating trusted video conferencing, the network sending and receiving thread is generally used to undertake the task of encryption and decryption. Among them, when using some high-efficiency or hardware-accele...
