摘要
移动自组网中的安全群组通信需要处理群组成员关系的动态性、成员位置的动态性、以及网络分区和合并等情况。如何高效地处理这些情况是移动自组网安全群组通信中要解决的重要问题。针对成员关系动态性、成员位置动态性和网络分区和合并带来的问题,提出研究与设计一种移动自组网中的“虚拟动态骨干网”模型。主要从组成员认证和组密钥管理两方面进行了研究,并基于虚拟动态骨干网提出了初步的解决方案。
Secure multicast communications in mobile Ad Hoc networks need to deal with some situations such as dynamic membership among group members, dynamic locations of group members, network partitions and merges, and so on. It is an important problem to tackle these situations efficiently secure multicast communications in mobile Ad Hoc networks. In order to solve problems brought by dynamic membership, dynamic locations and dynamic networks, the virtual dynamic backbone model is proposed for mobile Ad Hoc networks. Group member authentication and group key management issues are studied, which are based on our proposed virtual dynamic backbone model.
