Satellite Cybersecurity across Orbital Altitudes: Analyzing Ground-Based Threats to LEO, MEO, and GEO

The rapid proliferation of satellite constellations, particularly in Low Earth Orbit LEO, has fundamentally altered the global space infrastructure, shifting the risk landscape from purely kinetic collisions to complex cyber-physical threats. While traditional safety frameworks focus on debris...

Mutual Information Minimization for Side-Channel Attack Resistance Via Optimal Noise Injection

Side-channel attacks SCAs pose a serious threat to system security by extracting secret keys through physical leakages such as power consumption, timing variations, and electromagnetic emissions. Among existing countermeasures, artificial noise injection is recognized as one of the most effective...
