Abstract: A reactive jamming software defined radio (SDR) apparatus to target Frequency Hopping Spread-Spectrum (FHSS) signals includes a peripheral module for SDR processing; a reactive jamming hardware IP core that implements time-sensitive operations on a field programmable gate array (FGPA); and a host computer that implements non-time-critical operations, such as jammer configuration, logging, and strategy composition.

Abstract: A physical layer based technique secures wireless communication between a transmitter and receiver. The technique involves obfuscating the preamble data of the baseband signal through unique keys that are generated at the transmitter and the receiver based on channel characteristics known only to them.

Abstract: A key-based interleaver for enhancement the security of wireless communication includes a physical layer communication channel key to provide security even when the software encryption key is compromised. A method of creating a secure communication link using a physical layer interleaving system includes implementing a key policy implementation that utilizes temporal dependency and interleaving bits using a flexible inter and intra-block data interleaver.
