- Abstract
- It is necessary to have security for Wireless Sensor Networks (WSNs), which must be able to establish secure node to node communication. Sensor nodes should not have any a priori knowledge of which nodes will be close enough to be in their transmission range. And it is very likely that the topology of the network changes very frequently. Also a unicast based rekeying does not satisfy the security requirements of periodic rekeying for WSNs. Therefore, we propose a key management scheme for security and effective energy in WSNs. 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. Also, we 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.
