Review on security research of the Internet of things perception layer

Large-scale application of the Internet of things cannot do without security. The perception layer is at the bottom of architecture of Internet of things that assumes heavy responsibility of information perception. The security of perception layer is the main difference between Internet security and Internet of things security,and it is the focus of Internet of things security. Summarize security architecture of the Internet of things perception layer and security threats of perception layer;perception layer security includes RFID security and wireless sensor networks( WSNs)security and summarize the recent research achievements on this two aspects;put forward future research direction of RFID security and WSNs security;it can provide a reference for researchers who research on Internet of things security field.
