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.

模拟试验表明,提密钥管理在移动自网络中有良好性能。

Compared with the existing schemes, the proposed scheme can rekey real-time, provide a high level of security and reduce communication overhead at the same time.

与已有相比较，能实时地更新密钥，有着更好安全性并有较小通信开销。
