Video surveillance is an indispensable part of the construction of Ping an city, but the security of video content has always been an area not covered by Ping an city and municipal surveillance items, and the information in all camera terminals is in a plaintext state. there is a hidden danger of being stolen and tampered with. With the large-scale launch of Ping an city projects around the country, the government's requirements for Ping an city construction are also increasing, and the security protection of video content is also gradually appearing in various video surveillance projects.

Wanxietong video encryption scheme provides a standard and brief solution for video surveillance manufacturers.

The whole scheme is presented in the form of an encryption module. The encryption module is connected with the main device through the USB interface. The main device sends the plaintext video to the encryption module, and then the encryption module transmits back to the main device to complete the whole encryption process. Features: 1) easy to use: as a functional expansion module of the user product, it will not make too many hardware changes to the existing products. 2) High speed: the speed of video stream encryption is up to 8MB-12MB, which fully supports the current speed requirements for high-definition cameras. 3) scalability: the 32-bit high-speed processor in TF32A09 and large capacity flash space are used to provide users with an extended functional platform to achieve a variety of additional security functions, such as authentication, key self-destruction and so on.
