Abstract

With the development of wireless technology, the social daily life has an increasing relationship with the wireless networks and the issue of wireless network security has caught more and more attention. In this thesis, two new protocols for ZigBee security are proposed. For the first time public key technology has been used to enhance the security strength for ZigBee master key establishment. The proposed protocols strengthened ZigBee master key establishment security, which subsequently secure the establishment of the network key and link key, both derived from the master key. By integrating unbalanced RSA into the key establishment protocols, the new methods can distribute different computation amount to the ZigBee devices in communication based on their computational capacities. An efficient key establishment protocol for Bluetooth is proposed. It also utilizes public key technology to avoid the involvement of a third party and to improve the security strength. This proposed work requires fewer protocol steps and is thus faster than the existing similar works.
