| Abstract: | Group key and pair-wise key were used in key management of heterogeneous cluster wireless sensor networks based on the structure and applications of the network.The group keys would be updated each session according to dual directional hash chains based self-healing group key distribution scheme.Each pair of nodes that needs to communicate with the other established pair-wise key in the manner of bilinear pairings.Pair-wise keys would be also updated each session together with group keys in a non-interactive way.The analysis shows that the scheme supports node addition and revocation.And its good efficiency,high security performance and perfectly acceptable resource overhead make it attractive for centralized management of wireless sensor networks. |
