【摘要】:6LoWPAN——一種近距離的新型無線技術(shù),具有功耗低、成本低、傳輸可靠、容量大等特點(diǎn),應(yīng)用在短距離范圍內(nèi)的低速率傳輸上,尤其在WSN方面的應(yīng)用越來越廣泛。作為一種新興的無線網(wǎng)絡(luò),它既有傳統(tǒng)有線網(wǎng)絡(luò)的難以相比的優(yōu)點(diǎn),也存在一些無法克服的缺點(diǎn)。針對6LoWPAN網(wǎng)絡(luò)的攻擊者不必受限于6LoWPAN能量有限的特點(diǎn),而且沒有物理上的隔離,因此6LoWPAN網(wǎng)絡(luò)存在很大的安全威脅,保證其安全性成為日益突出的問題。本文以6LoWPAN協(xié)議棧為基礎(chǔ),對6LoWPAN節(jié)點(diǎn)的安全機(jī)制進(jìn)行了設(shè)計(jì)與實(shí)現(xiàn)。 本文論述了6LoWPAN安全機(jī)制的研究背景、意義和國內(nèi)外研究現(xiàn)狀;介紹了無線傳感器網(wǎng)絡(luò)技術(shù)、IEEE802.15.4技術(shù)、IPv6技術(shù)和6LoWPAN技術(shù);設(shè)計(jì)了6LoWPAN安全體系結(jié)構(gòu);分析了IEEE802.15.4協(xié)議的安全機(jī)制以及它所存在的安全漏洞,對其安全漏洞進(jìn)行改進(jìn),,設(shè)計(jì)并實(shí)現(xiàn)了MAC層安全機(jī)制;分析了6LoWPAN協(xié)議棧網(wǎng)絡(luò)層的存在的安全威脅,并根據(jù)6LoWPAN協(xié)議棧的特點(diǎn),設(shè)計(jì)并實(shí)現(xiàn)了6LoWPAN協(xié)議棧網(wǎng)絡(luò)層的安全機(jī)制;分析了應(yīng)用層密鑰分配與管理的方法,并對其進(jìn)行實(shí)現(xiàn)。最后通過實(shí)驗(yàn)測試了6LoWPAN協(xié)議棧安全機(jī)制的功能,驗(yàn)證了本設(shè)計(jì)的安全機(jī)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.
