Advanced Radio Frequency Technology for Wireless Network Security

Unlike a wired network, all communications in a wireless network is broadcast by nature, therefore prone to malicious attacks. Wireless information assurance (IA) is therefore of paramount importance to the healthy development of wireless technologies. Various forms of wireless information assurance and security measures have been proposed and implemented. They mostly rely on Layer-2 and above techniques only. In this proposal GIRD Systems proposes to develop and implement an innovative physical layer wireless IAS method and associated algorithms. By physically mitigating intrusion into a wireless network, this new physical layer method has the potential of achieving a higher wireless IA level. Further integration with the current and near future upper layer IA measures enables this new system to provide even a higher overall level of wireless IA.
