具有前向安全的Ad Hoc密钥管理方案

Scheme of Key Management in Ad Hoc Network with Forward Security

在完全分布式CA模型的基础上,结合信任度动态评估策略,提出了一种具有前向安全的密钥管理方案。使用NS-2仿真软件进行仿真实验,结果表明,当网络中节点数目的不同时,节点的认证成功率和节点延迟均保持稳定,提高了Ad Hoc网络的安全性与可用性,降低了系统开销。

On the basis of the fully distributed CA model, and combined the value of trust in dynamic assessment strategy, a scheme of key management in Ad Hoc network with forward security was proposed. Simulation results of NS-2 show that the success rate of certification and the certification detention for the different number of the network node are keep stable, and the availability of the Ad Hoc network is improved, and the system overhead is reduced.
