可信视频监控系统架构设计研究

Research and Design of Security Framework for Trusted Video Surveillance System

视频监控系统面临着一系列安全问题,频频出现视频监控假冒、窃取和非法控制事件。基于可信计算技术,设计了可信视频监控系统安全架构。该架构对系统中的计算设备实施可信安全增强,设计了基于数字证书的双向认证协议,对传输的视频和信令数据进行加密保护。系统验证和分析结果表明,该架构有效提高了视频监控系统的安全防护能力。

Video surveillance system （VSS） are facing increasing, persistent, and various cyber security threats, with lots of fake, data theft and illegal control events. Utilized the trusted computing, we proposed a security framework of trusted video surveillance system. This framework provides trust security enhancement for compute devices in the VSS, mutual authentication based on digital certificates, and encryption and integrity protection for Video and SIP command. The validation results indicate that the security framework can improve the defense capabilities.
