移动自组网络组密钥管理框架

A New Group Key Management Framework for Mobile Ad-Hoc Networks

许多应用于军事、紧急救灾等场合的移动自组网络需要安全组通信支持 ,然而节点的移动性、链路不可靠以及多跳通信延迟等特点使移动自组网络的组密钥管理面临巨大的挑战 基于秘密共享机制和RSA非对称机密体制提出了一种新的移动自组网络组密钥管理框架DGKMF ,该框架具有不依赖网络拓扑结构、组密钥局部生成以及有效维护组密钥的一致性的特点 模拟实验表明 。

Many emerging mobile wireless applications for emergency and military situations depend upon secure group communications But group key management in mobile ad hoc networks faces a great challenge because of mobility, unreliable links, and multi hop communications Based on the threshold secret sharing mechanism and RSA encryption technique, a novel group key management framework named DGKMF (distributed group key management framework) is proposed in this paper, in which each entity holds a secret share and multiple entities in a local neighborhood can jointly update the group key Simulation results demonstrate that DGKMF is better than other algorithms and protocols such as CKD, GDH v 2 and BD in the group rekey success ratio and delay
