ABSTRACT: Network security is an important issue especially in wireless networks where the network is open and the network perimeter is not exactly known. This leads them to be more vulnerable to attacks such as eavesdropping, message interception and modifications. Several of security protocols for wired-line networks have been adopted for use in wireless networks. However, they may not be suitable for wireless networks and devices since several assumptions applicable in in wired-line networks may not be valid in wireless networks. For example, wireless devices often have limited battery power, and by performing several message exchanges used in typical wired-line security protocols may rapidly deplete the devices' battery. It is also known that bandwidth is often limited in wireless networks. Thus, excessive message exchanges could degrade the performance of wireless networks. In this thesis, we propose work to classify energy saving mechanisms for security protocols in wireless networks. We apply these energy saving mechanisms to existing security protocols to demonstrate the reduction in energy consumption. Finally we propose schemes that can lead us to providing security services in energy efficient ways.
