物联网技术及安全问题

Technology and Security Issues of Internet of Things

物联网被称为继计算机和互联网之后的第三次信息技术革命,其应用无处不在,而物联网的安全问题直接关系到它的广泛应用。从物联网的安全构架和特点出发,阐述了物联网三层体系结构中存在的安全问题,提出了解决方案和涉及到的关键技术,对感知层的安全措施进行了具体的阐述,包括密钥管理算法、安全路由协议、数据融合技术以及身份认证和访问控制,等等。最后介绍了物联网的典型应用和发展前景。

Internet of things is called the third IT revolution following the computer and the internet, and now it is everywhere. The security issues of the lnternet of Things （IoT） are directly related to the wide application of its system. Beginning with introducing the architecture and features of loT security, this paper expounds several security issues of IoT that exist in the three-layer system structure, and comes up with solutions coupled with key technologies involved. Among these safety measures concerned, those in perception layer are particularly elaborated, including key management and algorithm, security routing protocol, data fusion technology, as well as authentication and access control, etc. The paper also presents the typical application and future prospect of the internet of things.
