Study Of Things Networking Perception Layer Security Authentication And Key Management

The Internet of things technology has the function of "double-edged sword". On the one hand, brings convenience to us, but also bring many unsafe factors in hand. In more and more emphasis on the dignity of life and quality of life today, with production, life of Internet of things people's security have become increasingly prominent, especially the authentication and key management perception layer now has been the key problem has become one of the research of the Internet of things, it is the basic guarantee to the safe operation of the Internet of things. This paper introduces the concept and architecture of the Internet of things, and has made the analysis on the security problems faced. Due to the RFID and wireless sensor network as the representative of the things networking perception layer has the characteristics of limited computing and storage capacity, and its present situation of endemic and security mechanism in the Internet of things is still relatively weak, to provide authentication technology and key management model for the sensing layer.
