Problems solved by technology

However, due to the limited computing power of the APU of the network camera, and the APU of the network camera needs to bear the computing tasks generated by most of the software in the network camera when it is running, it may take a lot of time to complete the encryption of the original video, and it is difficult to realize the encryption of the video data. Real-time encryption, resulting in a delay in the video previewed by the user

Abstract

The embodiment of the invention provides a network camera, a video encryption transmission system and a video encryption method. The network camera includes: an application processor, used to send the AES key to the smart chip through an encrypted channel; and send the original video data to the smart chip of the network camera through a transmission channel; the smart chip of the network camera is used to use the AES The key encrypts the original video data of the network camera to obtain encrypted video data; and sends the encrypted video data of the network camera to the application processor of the network camera through the encryption channel of the network camera; the switching module is used to provide the encryption channel of the network camera and the transmission channel of the network camera , in order to realize the data communication between the application processor of the network camera and the intelligent chip of the network camera. Real-time encryption of video data can be realized without increasing the cost of hardware by invoking the powerful computing power of the smart chip, reducing the delay caused by video encryption.

Description

technical field [0001] The invention relates to the technical field of embedded software systems, in particular to a network camera, a video encryption transmission system and a video encryption method. Background technique [0002] A network camera (Internet Protocol Camera, IPC for short) can send the collected video data to a remote audio and video client (hereinafter referred to as the client) for previewing by the user. In order to improve the security of video data transmitted between the network camera and the client, the network camera can encrypt the collected video data, and then send the encrypted video data to the client. [0003] In the prior art, the application processor (Application Processing Unit, referred to as APU) of the network camera can be based on the local operating system. After the audio and video collection is completed and the original video data is obtained, the original video data is encrypted to obtain encrypted data. video data. However, d...
