The Information Security for the Application of IoT Technology

With the wide use of IoT technology in the production and daily life, the problems of information security and privacy security have been gradually exposed. Based on the IoT technology architecture, we made a deep analysis of the security problems from the sensor layer, network layer and application layer respectively, and we try to find the key technical points and put forward the corresponding countermeasures and suggestions for the security problems in the above three layers, for example, the security problems of the terminal access mechanism and the routing attacks of wireless sensor networks for the sensor layer; the address space shortage and the denial of service due to network congestion for the network layer; personal privacy and unsound security standard for the application layer.
