The recent research in the field of cybersecurity and embedded systems has seen significant advancements in the areas of random number generation, jamming attacks, sensor manipulation, and power side-channel attacks. Innovations in oscillator-based True Random Number Generators (TRNGs) have focused on improving the precision of differential measurements to enhance security, addressing the need for individual oscillator jitter parameters. In the realm of wireless network security, smart jamming attacks on 5G systems have been modeled and practically implemented, demonstrating high effectiveness with minimal resource interference. Sensor deprivation attacks on Unmanned Aerial Vehicles (UAVs) have been explored, revealing vulnerabilities in sensor reconfiguration that can lead to catastrophic control failures, evading current anomaly detection systems. Additionally, power side-channel attacks have been extended to broader embedded systems security contexts, overcoming challenges related to noise and attacker assumptions through novel signal-processing techniques. These developments collectively highlight a shift towards more sophisticated and targeted attack methodologies, necessitating the development of advanced countermeasures to maintain system integrity and security.
