旨在分析物联网安全架构,并总结关键技术特点。通过结合信息安全的完整性和机密性,将信息安全的可用性特点体现,对物联网安全需求分析,结合物联网当下的安全问题,将科学合理的物联网安全系统架构提出,注重信息安全的保证,对独立性的安全架构建立,实现感知层和传输层信息的安全保证,并做好处理层信息的处理,在信息应用安全层中做好身份认证和访问控制,实现可信终端以及安全审计的过程。基于安全关键技术的发展中,结合物联网的安全需求,对密钥管理技术和安全路由协议做了具体的分析,指出密钥管理系统可以结合互联网中心的一种集中式管理方法,同时也可以采取网络为中心的一种分布式管理过程。对物联网安全架构关键技术的深入研究,对于物联网可靠安全信息体系的完善有着指导性意义。
Designed to analyze IoT security architecture and summarize key technical features. Combining the integrity and confidentiality of information security, this paper presents the availability characteristics of information security, analyzes the security requirements of IoT, and combines with the current security issues of IoT, puts forward a scientific and rational IoT security architecture and emphasizes the assurance of information security , Establish the security architecture of independence, realize the security assurance of the perception layer and transport layer information, and handle the processing of layer information, make identity authentication and access control in the information application security layer, implement the trusted terminal and the security audit the process of. Based on the development of security-critical technologies, the key management techniques and security routing protocols are analyzed in detail based on the security requirements of Internet of Things. It is pointed out that the key management system can be combined with a centralized management method of the Internet center, Take the network as the center of a distributed management process. The in-depth research on the key technologies of IoT security architecture is instructive for the improvement of IoT reliable security information system.
