Abstract

Wireless sensor network emerges as the backbone of the next generation technologies. The sensor nodes in the network have limited resources, which arise network scalability and security issues. The symmetric key establishment technique used for establishing connections in WSN limits the network scalability. If we distribute the keys to the nodes in advance the scalability could be increased. The unital design theory could be used for this purpose by mapping the unitals to pair wise keys. Although this could increase the scalability of the network, the key sharing probability decreases. An enhanced unital based technique could be used to increase the scalability without decreasing the key sharing probability. The U-key network is able to achieve good scalability level without compromising the performance and security of the network.
