Research on authentication methods for video devices based on embedded MCU

Abstract

In recent years, with the continuous development and maturity of surveillance video technology, the complexity of the network environment, video surveillance identity security issues have become more and more prominent, and more and more surveillance video identity security issues are mentioned. How to ensure that the front-end device identity security access to the video surveillance system has become an urgent problem. In this paper, according to the "GB35114 public security video surveillance networking information security technical requirements" in the A-level standard requirements, designed a based on embedded MCU chip communication technology, to ensure that the front-end equipment legitimate access to video surveillance system security feasible program. The program uses the MCU chip to do data signature processing, data scheduling through DMA, and the front-end device authentication information with the SIP authentication server with security features for authentication. The method is low in complexity and can adapt to a variety of scenarios for signature verification. It promotes the further development of video surveillance security technology and applications, improves the security of video content, and thus protects the rights and interests of users.
