IPv6链路本地地址安全技术研究

IPv6协议虽然在某些方面增强了安全性，但同时也引入了新的安全风险，因此网络安全威胁在IPv6时代依旧存在。通过从IPv6地址、报文格式和相关协议等方面分析了IPv6可能带来的安全新问题，分析IPv6报文结构和IPv6链路本地地址的结构。结合物联网的应用范围和特点，研究了ND协议的应用原理和ND协议的无状态地址技术在物联网中的应用过程。根据物联网中存在安全隐患的特点，从链路本地地址结构出发，提出了基于“贝特反转”的IPv6链路本地地址安全技术。

Study of Link-Local Address Security in IPv6

Although in some aspects of IPv6, enhanced security, but it also introduces new security risks, so the network security threats still exist in the IPv6 era. From the IPv6 address, message formats and related protocols and other aspects of the IPv6 security may bring new problems,aimed at overcoming the analysis of IPv6 date packet and link-local address, based on the domain and way of the lntemet of things, analyze and research on the Intemet of things features of neighbor discovery protocol and the unspecified address automatic identification. As result view,＂ the bit inverse proportion ＂was presented based on the security requirement of the lnternet of things and IPv6 date packet.
