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 prevent more attacks than other protocols.

Ubiquitous computing has been studied extensively as a post desktop model. Secure communication among various heterogeneous networks is been a challenge in service environment with location dynamism of the nodes. In this paper the authors proposed model for trust worthy communications among devices of various networks in a ubiquitous environment with varied service needs, security needs and computational-storage capacities. The model uses a novel approach for computing trust - adaptive to capacity and services.
