摘要
物联网是计算机、互联网与移动通信网等相关技术的演进和延伸,其安全问题愈来愈受到关注。该文对物联网安全进行深入研究,对其体系结构进行分析,并将其应用模型抽象为"物、网、应用";将其安全需求概括为"谁家的物归谁管,谁家的物归谁用"。该文将"物"抽象为四类,即感知类物、被感知类物、被控制类物及感知和被控制类物,并针对每一类"物"的应用提出了具体的解决方案,同时也提出了"网"与"应用"的安全解决方案。
IoT（internet of things） is the evolution and extension of related technologies such as computer, Internet and mobile communication network, and its security issue attracts more and more attention. An in-depth study of IoT security is done, and its architecture analyzed. Meanwhile, its application model is abstracted to things, network and applications, and its security requirements summarized as things only controlled and usecl by its owner. The things are abstracted to four categories in this paper, including perceiving things, perceived things, controlled things, perceiving and controlled things, and concrete solutions for each category are proposed. At the same time, security solutions for network and application are also proposed.
