Research On The Security In Internet Of Things

The continuous development of wireless communication, wireless sensor technology leads to the epoch-making emergence and promotion of the Internet of Things. Internet of Things combines with lots of disciplines, and has become one of the current hot spots of information technology. With the extensive applications of the Internet of things in many fields, it would trends to affect many major technological innovation and industrial development, and subject to the attention of governments, enterprises and research institutions. Though these applications even bring great convenience to the people’s production and life, information security issues of the Internet of Things brings enormous challenges. As a heterogeneous converged networks, Internet of Things not only has the same security problems as the Internet, sensor networks and mobile communication networks, however, because of its particularity, but also it confronts various troubles of privacy protection, which is considered by researchers as the bottleneck for further development of Internet of Things. Consequently, how to protect user privacy in the Internet of Things becomes the insistent problem to be resolved.This dissertation firstly studies the foundational knowledge in depth. Secondly, through the analysis&summarization on privacy protection technology of the Internet of Things, aimed at the security consideration, it designs a flexible privacy protection scheme based on application scenario and a query-based protection scheme according to the characteristics of Internet of Things. After that, it applies the protection schemes metioned above in the medical health care scene environment. Finally, the architecture of the smart home system is proposed, and it implements the security privacy protection platform based on the design&realization of hardware and software.
