Approved for public release; distribution is unlimited / The advent of Wireless Local Area Networking (WLAN) has seen a widespread adoption of its technology and functionality in many different areas. Many studies show more and more organizations are extending their networks to incorporate wireless devices and their applications. Permitting wireless devices to access private networks however, further complicates the tasks of protecting the network and its resources from unauthorized access. Now that they have become a significant element in today's networks, selecting and deploying adequate security measures have become the focus of many research efforts. Typically, network managers implement countermeasures to augment security. The goal of this thesis is to research approaches that compliment existing security measures with fine grain access control measures. The Extensible Markup Language (XML) is adopted to accommodate such granular access control as it provides the mechanisms for scaling security down to the document content level. / Captain, United States Marine Corps

Approved for public release; distribution is unlimited / of IEEE 802.11a standard. The signal is subject to pulsednoise jamming, when either the desired signal alone or the desired signal and the jamming signal are subject to Nakagami fading. As expected, the implementation of forward error correction (FEC) coding with soft decision decoding (SDD) and maximumlikelihood detection improves performance as compared to uncoded signals. In addition, the combination of maximum-likelihood detection and error correction coding renders pulsed-noise jamming ineffective as compared to barrage noise jamming. When the jamming signal encounters fading as well, we assume that the average jamming power is much greater than the AWGN power. For uncoded signals, a jamming signal that experiences fading actually improves performance when the parameter of the information signal s m is less than or equal to one. Surprisingly, for larger values of s m a jamming signal that experiences fading works in favor of the information signal only for small signal-tointerference ratio (SIR). When SIR is large, performance when the jamming signal experiences fading is worse relative to performance when the jamming signal does not experience fading. For error correction coding with SDD, we investigate only continuous jamming since it is by far the worst-case. Moreover, while we consider a range of fading conditions for the jamming signal, we examine only Rayleigh fading of the information signal. The coded signal, when the jamming signal experiences severe fading, performs better relative to the case when the jamming signal does not experience fading. / Lieutenant Junior Grade, Hellenic Navy

Approved for public release, distribution unlimited / Wireless Local Area Networks (WLANs) are quickly becoming popular in daily life. Users are adopting the latest technology to save time and costs. In addition, WLANs are providing high-speed network access to the users. There are security concerns with WLANs that must be considered when deploying them over critical infrastructure, such as military and administrative government LANs. The IEEE 802.11 wireless standard specifies both an authentication service and encryption protocol, but research has demonstrated that these protocols are severely flawed. The IEEE has established a new workgroup, the IEEE 802.11i, to address all the security vulnerabilities of the 802.11 security protocol. The workgroup proposed using the IEEE 802.1X Port-Based Network Access Control Standard as an interim measure to meet the security requirements of the WLANs and to maintain the confidentiality, authenticity, and availability of the data until the workgroup is finished with the new specifications. Using an open-source test-bed for evaluating DoS attacks on WLANs, this research demonstrates four different DoS attacks that verify the weaknesses of the IEEE 802.1X protocol. Solutions are provided to mitigate the effects of such DoS attacks. / Lieutenant Junior Grade, Turkish Navy

The ZigBee standard is a wireless networking standard created and maintained by the ZigBee Alliance. The standard aims to provide an inexpensive, reliable, and efficient solution for wirelessly networked sensing and control products. The ZigBee Alliance is composed of over 300 member companies making use of the standard in different ways, ranging from energy management and efficiency, to RF remote controls, to health care products. Home automation is one market that greatly benefits from the use of ZigBee. With a focus on conserving home electricity use, a sample design is created to test a home automation network using Freescale's ZigBee platform. Multiple electrical designs are tested utilizing sensors ranging from proximity sensors to current sense transformers. Software is fashioned as well, creating a PC application that interacts with two ZigBee transceiver boards performing different home automation functions such as air conditioner and automatic lighting control. / by Michael G.
