物联网感知层安全性研究综述

摘要

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.%物联网的大规模应用离不开安全性的保障。感知层在物联网体系结构中处于底层，承担信息感知的重任。感知层的安全问题是物联网安全与互联网安全主要的差别所在，是物联网安全的重点。针对物联网感知层的安全架构、感知层的安全威胁进行了分析总结；从无线射频识别（ RFID）安全、无线传感器网络安全两个方面总结了近年来物联网感知层的安全性研究成果；提出了RFID安全和无线传感器网络安全的未来研究方向；给物联网安全领域的研究者提供一定的参考。
