低功耗有损网络安全路由协议研究综述

Research summary of secure routing protocol for low-power and lossy networks

随着物联网不断飞速发展,低功耗有损网络(LLN)的研究与应用成为一种发展趋势。首先,介绍了6LoWPAN与低功耗有损网络路由协议(RPL)的基本原理和结构;其次,总结了LLN中RPL所面对的主要安全威胁以及应对方法,根据协议所采用的不同策略进行归纳、分类和比较;然后,对国内外已有安全RPL研究情况进行了介绍和分析,同时对现有安全威胁和解决方案进行了总结;最后,提出了在大规模、移动性、自组织、低功耗的RPL中需要进一步研究的安全问题和发展趋势。

With the rapid development of the Internet of Things(IoT),the research and application of Low-power and Lossy Network(LLN)has become a trend of development.Firstly,the basic principle and structure of IPv6over Low-power Wireless Personal Area Network(6LoWPAN)and Routing Protocol for Low-power and lossy network(RPL)were introduced.Secondly,the main security threats of RPL routing in LLN and the corresponding solutions were summarized,classified and compared through the different strategies adopted by the protocol.Then,the research status of existing secure RPL at home and abroad was introduced and analyzed.At the same time,the existing security threats and solutions were summarized.Finally,the security issues and development trends that needed to be further studied in large-scale,mobile,self-organizing and low-power RPL were proposed.
