Research on Video Surveillance Security System Based on Domestic Password

Video surveillance system has become the most important technical means to maintain public security. With the increasingly wide application of video surveillance system, it has also become an important target of network attacks. Video surveillance system has different kinds of security risks in front-end equipment and background system. It is becoming a consensus in the international security field to build a video surveillance security technology system to effectively resist network attacks against video surveillance system and ensure the security of video data. In this paper, we take the monitoring system of session initiation Protocol (SIP) as an example, use domestic cryptographic technology to build video surveillance security protection framework, and comprehensively use bidirectional authentication, video stream encryption, video stream and signaling integrity validate and other technologies to improve the comprehensive security protection level of video surveillance.
