Network architecture security system for Internet of Things and security method thereof

Abstract

The invention aims at providing a network architecture security system for Internet of Things and a security method thereof, comprising security protective measures sequentially established in the system from inside to outside, which are mainly reflected in that a security device at a central terminal of the Internet of Things comprises a central cipher machine, a central authentication secret key management center, a data server, a security database and the like, and then the security of each sensor terminal in a Personal Area Network and the like. Compared with the prior art, the invention has the advantages that: 1. according to the characteristics of the Internet of Things, Internet security technology of the Internet of Things is realized; 2. the security protective measures sequentially established in the system from inside to outside are mainly reflected in the security device at the central terminal and security modules at each sensor terminal, thus ensuring the security of sensing information, equipment, communication and application, as well as security management; and 3. multi-level security systems are deployed in the aspects of security mechanism and management, such as the confidentiality, integrity, authenticity and non-repudiation of data, and equipment legitimacy.

Description

technical field [0001] The invention relates to the security technology of the Internet of Things, in particular to a security system and a security method of the network architecture of the Internet of Things. Background technique [0002] The Internet of Things is an object-to-object network system. The Internet of Things serves humans by sensing changes in various objects and extracting perceived information. Therefore, the Internet of Things as a next-generation network is booming in the world today. The Chinese Premier proposed "perceiving China", and US President Obama proposed concepts such as "Smart Earth". With the rapid development of Internet of Things technology, various Internet of Things technologies and means are also undergoing profound changes. The security of the Internet of Things has been greatly challenged. [0003] First, the sensor network is an environment with serious uncertainties. The widespread sensing intelligent nodes are essentially monitor...
