Abstract
Video command and dispatch systems have become essential communication safeguard measures in circumstances of emergency rescue, epidemic prevention, and control command as, data security has become especially important. After meeting the requirements of voice and video dispatch, this paper proposes an end-to-end encryption method of multimedia information that introduces a multiple protection mechanism including selective encryption and selective integrity protection. The method has a network access authentication and service encryption workflow, which implants startup authentication and key distribution into the information control signaling procedure. This method constitutes a key pool with the three-dimensional Lorenz System, the four-dimensional Cellular Neural Network (CNN) System and the four-dimensional Chen System where the key source system and initial conditions are decided by the plaintext video frame itself. Then, this method optimizes the chaotic sequences to further enhance system security.
Highlights
As a kind of real-time communication system relying on image and voice communication, video systems enable geographically dispersed users to gather in one virtual conferencing space as the various information exchange modes through image and voice enable real and visualized exchange of cooperating members, and facilitate participant understanding of conference content (Yang et al, 2014)

Summary
As a kind of real-time communication system relying on image and voice communication, video systems enable geographically dispersed users to gather in one virtual conferencing space as the various information exchange modes through image and voice enable real and visualized exchange of cooperating members, and facilitate participant understanding of conference content (Yang et al, 2014). This paper extracts cryptographic demands from typical video conferencing systems and designs a video conferencing encryption scheme using research in combination with commercial cryptographic algorithm, and by taking full advantage of chaos algorithm. This is done to guarantee the information data security, ensure the sustainable development and secure application of video conferencing. This paper proposes an end-toend encryption scheme for multimedia information in video synergic command systems which studies, combines and designs technologies such as user authentication, end-to-end information encryption protocol, and chaotic encryption algorithm. This implements the video synergic command system and meets various personalized user demands for multimedia information encryption
