摘要: 随着物联网设备在开放互联网上的快速部署,物联网设备的隐私和通信安全问题得到广泛关注。由于物联网的嵌入式设备受到资源和计算性能的限制,传统的网络通信安全方法难以提供可靠的安全保障。为此,提出一种基于低功耗无线个域网6LoWPAN的轻量级IPv6地址跳变协议(L6HOP)。通过对移动目标IPv6网络防御(MT6D)协议进行改进,使用轻量级哈希算法降低CPU计算消耗,并引入滑动地址窗口解决不同设备时钟误差引起的丢包率较大的问题。实验结果表明,L6HOP协议可有效保护物联网不受设备追踪、DoS和窃听等攻击,与MT6D协议相比,可有效减少CPU的计算开销,并能够降低通信丢包率。

Abstract: With the rapid deployment of Internet of Things(IoT) devices on the open Internet,the privacy and communication security of IoT devices has attracted much attention.Because the embedded IoT devices are limited by resources and computing performance,traditional network communication security methods have been unable to provide reliable security guarantee.Therefore,this paper proposes a lightweight IPv6 address hopping protocol,L6HOP,in the low-power wireless personal area network,6LoWPAN.The protocol improves the Moving Target IPv6 Defense(MT6D) protocol,and uses a lightweight hash algorithm to reduce CPU computing consumption.Also,the sliding address window is introduced to solve the high packet loss rate caused by clock errors of different devices.Experimental results show that the L6HOP protocol can effectively protect the IoT from device tracking,DoS and eavesdropping attacks.Compared with MT6D protocol,it can significantly reduce the computing overhead of CPU and packet loss rate of communication.

Key words: Internet of Things(IoT), address hopping, security protocol, Moving Target IPv6 Defense(MT6D) protocol, communication efficiency
