Localization-based clustered key management in wireless sensor network

Wireless Sensor Networks (WSNs) are usually subjected to numerous threats and vulnerable to various attacks. Generally, the key management is considered to be the prerequisite for secure communication in WSNs. In this paper, we present a Localization-based Clustered Key Management (LCKM) which can efficiently enhance the network security and survivability for the clustered heterogeneous networks. LCKM utilizes the seeds to rekey and then localize the key materials, which protects the network from the compromised nodes by reducing the probability of the common key. The security analysis proves that LCKM can effectively prevent more attacks than other protocols.
