摘要
首先介绍了物联网的基本概念和物联网的三层体系结构,概括了物联网安全的新挑战和物联网安全大众化、轻量级、非对称、复杂性等主要特点,然后分别从感知层、网络层和应用层分析了物联网的安全威胁,最后提出了物联网安全体系结构。物联网安全需要对物联网感知层、网络层和应用层进行有效的安全保障,以应对其面临的安全威胁,并且还要能够对各个层次的安全防护手段进行统一的管理。
This paper first gives the concept and three-layer architecture of IOT（Internet of Things）, summarizes the new security challenge to lOT and its main features including popularity, lightweight, non-symmety, complexity, and then analyzes the security threats against perception layer, network layer, application layer of lOT, and finally it gives the security architecture for IOT. The security measure should of the ability to protect perception layer, network layer, application layer of lOT, cope with the security threats of against IOT, and implement the management of all security measure.
