An efficient key management scheme in sensor network

초록

We propose a key management scheme in sensor networks. Using an allocation of a location based group key for secure group communication, the proposed scheme provides the revocation of compromised nodes and energy efficient rekeying. We address the main function using a broadcast based rekeying for low energy key management and high resilience and analyze the efficiency of our proposed scheme mathematically. We show that our proposed scheme performs better than other protocols, especially when the large scaled distributed sensor networks. ©2010 IEEE.
