摘要：NVR is a network video surveillance system that can be used in the Internet environment. Through the system, the user can acquire image information remotely and use it for various purposes. However, when cameras connected to the network or not connected to the network are connected to the Internet, security problems such as unauthorized access and leakage of image information occur. Therefore, this paper can solve various threats effectively by encrypting image information generated in IP CCTV through symmetric key group key management.
