Self-Healing Group Key Distribution Scheme with Long Life-Time for Wireless Sensor Networks
Zhao Ze-mao · Chuangan jishu xuebao · 2011
In order to resolve the problem that the current self-healing group key distribution schemes are only able to support m sessions,an efficient δ-self-healing group key distribution scheme with revocation capability is proposed.The proposed scheme is capable of supporting infinite sessions by updating the private key of the group member nodes during each session and performing a partial revocation.Security and performance analysis and simulation results show that the proposed scheme has settled the life-time extension problem yet still achieved security property and lowered the storage and communication costs.
