Dynamic Key Management Scheme for Wireless Sensor Networks
Yourong Chen · Chuangan jishu xuebao · 2008
For many traditional key management schemes unfit for the constrained resource nodes in wireless sensor networks, how to reduce energy consumption of nodes and guarantee the security of the network becomes the important target of key management schemes. A Two-Tier Dynamic Key Management (TDKM) Scheme was proposed. This scheme includes location-ware pair-wise keys in cluster nodes sessions and location-based combinatorial keys in nodes communications. With comparing the SECK scheme, the TDKM scheme overcomes high refreshing cost and improves the security performance.
