Abstract:

Nowadays, the Internet of things technology has been widely used in industry, agriculture, military, medical environmental protection and other fields, and all aspects of people’s life gradually into the era of “everything was connected”. With the continuous development of the Internet of things technology, information transmission and information security requirement are higher and higher in the process of “everything was connected”. Identity authentication problem is the first barrier to guarantee the safety of IoT system. Therefore, the study for it has a long way to go. This paper introduces the basic concept of Internet of things as well as the classification and characteristics of the perception layer tags, and do key research and analysis on the Internet security threats in the open system of existing security protocols. This paper researches the RFID electronic tags based on the important technologies of the Internet of things. On the basis of universal model and the improved model of RFID authentication protocol, and on account of Hash function and public key encryption algorithm, we design a bidirectional authentication protocol, which can be able to quickly identify information and to ensure the safety of Internet system.

Key words: Internet of things, RFID, electronic tags, identity authentication
