Low-PAPR Waveforms with Shaped Spectrum for Enhanced Low Probability of Intercept Noise Radars [PDF]
Remote Sensing, 2021 Noise radars employ random waveforms in their transmission as compared to traditional radars. Considered as enhanced Low Probability of Intercept (LPI) radars, they are resilient to interference and jamming and less vulnerable to adversarial exploitation

Quantum Low Probability of Intercept
Conference on Lasers and Electro-Optics, 2019 Conventional cryptography—such as the Rivest–Shamir–Adleman public-key infrastructure—may be rendered insecure by the ever-increasing capabilities of classical computers and the emergence of quantum computers. Quantum key distribution and post-quantum cryptography are presently being pursued as solutions to the quantum threat, but they offer no ...
