| Popis: | 91 Wireless Sensor Networks (WSNs) are formed by a set of small devices with limited computing power and wireless communication capabilities. Those sensor nodes will be deployed on a specific area to monitor a physical phenomenon. The security services are considered more and more important for WSNs. The key distribution is regarded as the critical and fundamental issue for security services. In this thesis, we proposed two key distribution schemes for WSNs to improve the memory storage requirement. Adaptive Random Pre-distributed scheme (ARP scheme) achieves better performance in memory space requirement with a given level of security strength. It would be useful in minimizing the storage requirement for the resource limited sensor nodes. Unique Assigned One-Way Function scheme (UAO scheme) provides the characteristics of node-to-node authentication and great resistance against node capture. Moreover, UAO scheme achieves better performance in the complexity of required memory space and the network size than the existing schemes. |
