物联网多维度安全防御模型研究
Research on a multi-dimensional security defense model for the Internet of Things
摘要
Abstract
The traditional"perception-network-application"three-layer architecture of the Internet of Things(IoT)exhibits secu-rity blind spots at the edge.Meanwhile,the"six-domain model"faces challenges in practical implementation due to high deploy-ment costs and lack of inter-domain coordination mechanisms.Based on threat analysis across the physical,network,and service domains,this paper reconstructs a"terminal domain-edge domain-core network domain-cloud application domain"four-domain architecture and introduces a dual-layer control mechanism that decouples the data plane and control plane,proposing a"four-do-main dual-layer"security framework.This framework systematically reveals multi-dimensional threats including hardware infiltra-tion,protocol vulnerabilities,quantum computing impacts,and API semantic conflicts.It constructs models for terminal light-weight protection,quantum-enhanced transmission,server-side proactive defense,and full-lifecycle security management.Practi-cal tests in banking zero-trust scenarios and industrial IoT scenarios demonstrate that the attack detection rate is≥98%,and the average response time is≤500 ms.The results provide a reusable,systematic methodology for large-scale IoT security engineering.关键词
