摘要

摘要: 作为一类自组织动态网络，无线Ad hoc网面临着严重的安全威胁。该文在分析Ad hoc网络特点的基础上，提出一种基于扩展Diffie-Hellman交换的分级组密钥管理方案(HGKM)。HGKM协议采用分级架构，利用成员过滤函数维护统一的组密钥，有效减少密钥更新对Ad hoc网性能的影响。

Abstract: As a kind of dynamic self-organized network, wireless Ad hoc network is faced with serious security threat. On the basis of analyzing the characteristics of Ad hoc network, a hierarchical group key management solution (Hierarchical Group Controller-Based Group Key Management protocol) based on extended Diffie-Hellman protocol is presented. The HGKM utilizes member filter function and hierarchy to maintain a single group key to adapt to the special requirements for frequent key refresh of Ad hoc network.
