摘要
视频监控系统在经济领域应用广泛,面临的安全风险与威胁也日趋增多。基于国产密码技术设计安全的视频监控系统,是抵御攻击的根本手段。针对视频监控系统面临的各项安全威胁,提出一种基于标识密码的视频监控系统安全加固方案,基于SM9算法设计安全接入认证协议和密钥协商协议,在此基础上利用SM3、SM4算法实现信令加固和视频数据安全保护。有效实现了视频监控系统的安全防护,同时避免了频繁数字证书交换与认证带来的效率问题,适用于大规模、高安全要求的视频监控系统。
Video surveillance systems are widely used in economic field,and the security risks and threats they face are increasing day by day.Designing a secure video surveillance system based on domestic cryptography technology is a fundamental means to resist attacks.Aiming at the various security threats faced by video surveillance system,a security enforced solution for video surveillance system based on identity-based cryptography is proposed,and the secure access authentication protocol and key agreement protocol are designed based on the SM9 algorithm,on the basis of which the signaling reinforcement and video data security protection are achieved by using the SM3 and SM4 algorithms.The scheme effectively realizes the security protection of video surveillance system and at the same time avoids the efficiency problems caused by frequent digital certificate exchange and authentication,which is suitable for large-scale,high-security and other requirements of video surveillance system.
