物联网通信协议的安全研究综述

Security for Communication Protocols in Internet of Things:A Survey

国际标准化组织IEEE和IETF正携手为物联网制定一套高可靠、低功耗、可接入互联网的无线通信协议栈。IEEE主要负责制定物联网通信协议的物理层和链路层的标准,如IEEE802.15.4-2006标准,其中IEEE802.15.4e是最新的链路层的标准。IETF主要负责制定物联网通信协议的网络层及以上标准,如6LoWPAN,RPL和CoAP标准,其可以将资源受限的传感器节点接入互联网。网络安全是物联网大规模发展的基础,必须设计一套安全高效的机制保障通信协议的正常运行。文中详细介绍了物联网通信协议栈,重点分析和讨论了其安全方面的最新研究进展。最后总结和展望了物联网安全通信协议的研究方向。

The IEEE and IETF standardization bodies are working together to develop a framework for the communication protocols of the Internet of Things(IoT).The communication protocols can meet the important criteria of reliability,power-efficiency and Internet connectivity.The IEEE defines the physical layer and medium access control(MAC)layer standard such as IEEE802.15.4-2006,and IEEE802.15.4e is the latest MAC layer standards for the IoT.The IETF defines the network layer and above standards,such as 6LoWPAN,RPL and CoAP,which can connect the resource constrained sensor nodes to the Internet.Network security is the fundamental of large-scale development of IoT,so it is necessary to design some secure and efficient mechanisms to protect the communication protocols.This paper reviewed the communication protocols in the IoT,then analyzed and discussed the latest research progress of secure technologies for them.Finally,it summerized and looked ahead some important directions of secure communication protocols for IoT.
