发布时间：2018-10-31 18:40
【摘要】：6LoWPAN——一种近距离的新型无线技术，具有功耗低、成本低、传输可靠、容量大等特点，应用在短距离范围内的低速率传输上，尤其在WSN方面的应用越来越广泛。作为一种新兴的无线网络，它既有传统有线网络的难以相比的优点，也存在一些无法克服的缺点。针对6LoWPAN网络的攻击者不必受限于6LoWPAN能量有限的特点，而且没有物理上的隔离，因此6LoWPAN网络存在很大的安全威胁，保证其安全性成为日益突出的问题。本文以6LoWPAN协议栈为基础，对6LoWPAN节点的安全机制进行了设计与实现。 本文论述了6LoWPAN安全机制的研究背景、意义和国内外研究现状；介绍了无线传感器网络技术、IEEE802.15.4技术、IPv6技术和6LoWPAN技术；设计了6LoWPAN安全体系结构；分析了IEEE802.15.4协议的安全机制以及它所存在的安全漏洞，对其安全漏洞进行改进，，设计并实现了MAC层安全机制；分析了6LoWPAN协议栈网络层的存在的安全威胁，并根据6LoWPAN协议栈的特点，设计并实现了6LoWPAN协议栈网络层的安全机制；分析了应用层密钥分配与管理的方法，并对其进行实现。最后通过实验测试了6LoWPAN协议栈安全机制的功能，验证了本设计的安全机制的有效性。
[Abstract]:6LoWPAN- a new wireless technology with low power consumption, low cost, reliable transmission and large capacity, is widely used in low rate transmission in short range, especially in WSN. As a new wireless network, it not only has the advantages of traditional wired network, but also has some shortcomings that can not be overcome. Attackers in 6LoWPAN networks do not have to be limited by the limited energy of 6LoWPAN and do not have physical isolation. Therefore, there is a great security threat in 6LoWPAN networks, and it is becoming an increasingly prominent problem to ensure the security of 6LoWPAN networks. Based on 6LoWPAN protocol stack, this paper designs and implements the security mechanism of 6LoWPAN node. This paper discusses the research background, significance and current situation of 6LoWPAN security mechanism, introduces wireless sensor network technology, IEEE802.15.4 technology, IPv6 technology and 6LoWPAN technology, designs 6LoWPAN security architecture. This paper analyzes the security mechanism of IEEE802.15.4 protocol and its security vulnerabilities, improves the security vulnerabilities, and designs and implements the security mechanism of MAC layer. This paper analyzes the security threats in the network layer of the 6LoWPAN protocol stack, designs and implements the security mechanism of the network layer of the 6LoWPAN protocol stack according to the characteristics of the 6LoWPAN protocol stack, and analyzes the method of key distribution and management in the application layer, and implements it. Finally, the function of 6LoWPAN stack security mechanism is tested experimentally, and the effectiveness of the proposed security mechanism is verified.
