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.

Physical layer key based interleaving for secure wireless communication

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.

Physical gate based preamble obfuscation for securing wireless communication

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.

Energy-efficient reactive jamming of frequency-hopping spread spectrum (FHSS) signals using software-defined radios

Presenting a visualization of antenna radiation patterns may include sending a request to a server for up-to-date information regarding an antenna mode; receiving the request at the server and reading a register value for the antenna mode; responding, by the server, with updated antenna mode information; and overlaying antenna radiation patterns on an image based on the mode information.

Beam visualization and using augmented reality for control and interaction

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&#x2014;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.
