一种基于IPv6安全通信方案的移动扩展研究

ON MOBILE EXTENSION OF IPV6 BASED SECURE COMMUNICATION SCHEME

在对基于固定IPv6网路的安全通信方案进行研究和分析的基础上,提出了一种新的基于移动IPv6网络的安全通信扩展方案。通过对固定IPv6网络中的基于亲密伙伴的安全通信方案进行改进,并结合移动IPv6网络中移动节点的特性,提出了一种动态构建安全通信管理模式的新思想。以移动子网内部移动节点的预测驻留时间为标准来选取子网内部的管理节点。通过在移动网络中构造一个动态管理节点,妥善地解决了原方案在移动IPv6网络中的扩展问题。最后,通过对新方案进行了仿真和分析,证明了该方案的可行性。

Based on the study and analysis of existing fixed IPv6 network secure communication scheme, we propose a new extended secure communication scheme on mobile IPv6 basis. Through improving the closed members-based secure communication scheme in fixed IPv6 net- work, and combining with the characteristic of mobile nodes in mobile lPv6 network, we put forward a new thought in dynamically constructing a secure communication management mode. It sets the predicted dwelling time of mobile node within the subnet as the criterion to select network management node. Through constructing a dynamic management node in mobile network, the expansion issue of the original solution in mobile IPv6 network environment is solved properly. Finally, the simulation and analysis of this scheme is made and its feasibility has been proved.
