基于门限秘密分享技术,提出一种高效的分布式组密钥管理方案EDGK。方案在缺少可信中心和网络拓扑结构动态变化的环境中能有效地更新组通信密钥。模拟试验表明,提出的组密钥管理方案在移动自组网络中具有良好的性能。
Based on the threshold secret sharing mechanism, a new efficient distributed group key management scheme named EDGK was proposed. The presented scheme could efficiently update the Traffic Encryption Key(TEK) in the environment of lack of trusted centre and mobility of nodes. The simulation results show that, compared with the protocols, EDGK is better in the group rekey success ratio and delay in mobile Ad hoc network environment.
