Abstract

The embodiment of the invention provides a data encryption and decryption method and device, and the method comprises the steps: carrying out the analysis of received audio and video data, and obtaining a target instruction; generating secret key stream data under the condition that the target instruction comprises a secret key updating instruction and an encryption and decryption data caching instruction, and caching the audio and video data to obtain cached audio and video data; and performing data encryption and decryption based on the cached audio and video data and the key stream data toobtain encrypted and decrypted audio and video data. According to the embodiment of the invention, the requirements of OFB mode full encryption of data and simultaneous encryption and decryption functions of multiple paths of articulated naturality web equipment can be met.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data encryption and decryption method and device. Background technique [0002] Since the Internet of Vision technology can realize the real-time transmission of high-definition audio and video in the whole network, the Internet of Vision technology is more and more used in various large-scale conferences. Reliability, etc. have won unanimous praise from users. During the live broadcasting of video conferencing and video calls, etc., the audio and video data transmitted by the Internet of View devices needs to undergo complex encryption and decryption methods before being transmitted to the external network to ensure that the audio and video data meet the security requirements of all encryption and decryption or partial encryption and decryption. . [0003] At present, the traditional video network can encrypt and decrypt audio and video data through an encryption cor...
