6LoWPAN网络通过邻居发现协议检测邻居可达性、发现邻近路由和自动配置地址的过程中极易受到安全威胁。传统的IPv6安全协议大多计算繁琐,无法适用于节点能量有限的6LoWPAN网络。为简化对6LoWPAN网络中节点和链路的安全保护机制,本文提出了一种基于邻居发现的6LoWPAN节点安全接入机制,并设计了相应的节点安全接入流程。
6LoWPAN network through the neighbor discovery protocol to detect neighbors reachability, found near the routing and automatically configure the address vulnerable to security threats. Most of the traditional IPv6 security protocols are cumbersome to calculate and can not be applied to the 6LoWPAN network with limited node energy. In order to simplify the security protection mechanism of nodes and links in 6LoWPAN networks, this paper proposes a 6LoWPAN node security access mechanism based on neighbor discovery and designs the corresponding node security access process.
