Construction and Strategies in IoT Security System

[maruf.swe]

The Internet of Things (IoT) is the development production of the computer science and communication technology. As IoT is broadly used in many fields, the security of IoT is becoming especially important and will take great effects on the industry of IoT. Beginning with the concept of IoT, its features and systemic structure, this paper analyzes the security problem of IoT in the stratums of perception, network and application in the system of IoT, puts forward the secure construction of IoT, and offers the corresponding secure strategies based on the existing problems in the framework of IoT. And eventually the theoretical basis will be offered to build up reliable security system of IoT.
