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.

Abstract: A learning protocol for distributed antenna state selection in directional cognitive small-cell networks is described. Antenna state selection is formulated as a nonstationary multi-armed bandit problem and an effective solution is provided based on the adaptive pursuit method from reinforcement learning. A cognitive small cell testbed, called WARP-TDMAC, provides a useful software-defined radio package to explore the usefulness of compact, electronically reconfigurable antennas in dense small-cell configurations. A practical implementation of the adaptive pursuit method provides a robust distributed antenna state selection protocol for cognitive small-cell networks. Test results confirm that directionality provides significant advantages over omnidirectional transmission which suffers high throughput reduction and complete link outages at above-average jamming or cross-link interference power.

Abstract: A real-time capable, protocol-aware, reactive jammer using GNU Radio and the USRP N210 software-defined radio (SDR) platform detects in-flight packets of known wireless standards and reacts to jam them—within 80 ns of detecting the signal. A reactive jamming device is achieved using low-cost, readily available hardware. The real-time reactive jamming device includes a real-time signal detector that detects an event in received packets in the wireless network, a reactive jamming device that sends a triggering signal when the event is detected, and a jamming generator responsive to the triggering signal to generate a jamming signal that has a user-defined delay so as to enable jamming of specific locations in received packets in the wireless network. The effects of three types of jamming on WiFi (802.11g) and mobile WiMAX (802.16e) networks are demonstrated and jamming performances are quantified by measuring the network throughput using the iperf software tool.

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.
