摘要
物联网分布范围的广泛性、节点的移动性以及业务应用的复杂性给物联网的安全带来严峻挑战。根据物联网的架构和特点,划分物联网的安全体系,并分析了不同层面所面临的多种安全问题。分别从物联网末端节点、感知层、网络层、应用层、管理控制五个层面全面分析了物联网可能面临的多种安全威胁,并在此基础上提出了物联网面临的安全需求。
Internet of Things features a widely spread network with numerous end devices and varied applications.These features impose great security problems for IoT.This paper analyzed the characteristics of IoT security threats and proposed the architecture of IoT security system.Detailed security threats were analyzed for the end device,sensing layer,network layer,application layer,and management system of IoT.Security requirements of each layer were summarized at the end of this paper.
