Waveform Design for Secure SISO Transmissions and Multicasting

Message Authentication Schemes for Secure Multicasting

Multicast communication is becoming the basis for a growing number of applications. It is therefore critical to provide sound security mechanism for multicast communication. One such solution, secure multicast, is appealing because it leverages the efficiency of multicast data delivery. However, it also presents several research challenges. In this paper, we discuss a packet source authenticati...

Power Allocation Strategies for MIMO Radar Waveform Design

The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...

Waveform design in signal-dependent interference and application to target recognition with multiple transmissions

The authors present illumination waveforms matched to stochastic targets in the presence of signaldependent interference. The waveforms are formed by SNR and mutual information (MI) optimisation. We also use these waveforms in cognitive radar (CR) target identification application. In this application, the radar system attempts to identify a deterministic or random target using multiple transmi...

Differentially secure multicasting and its implementation methods

Though the areas of secure multicast group architecture, key distribution, and sender authentication are under scrutiny, one topic that has not been explored is how to integrate these with multilevel security. Multilevel security is the ability to distinguish subjects according to classification levels, which determines to what degree they can access confidential objects. In the case of groups,...
