Directional Cryptography & Anti-Spoofing Radar in ISACSecurity

Wireless communications are inherently broadcast, making them vulnerable to intercept, while radar systems face spoofing attacks via malicious signal repeaters and ghost target injection. ISACSecurity unifies communications cryptography with radar propagation physics, projecting artificial noise into non-target angular sectors while verifying the physical hardware fingerprints of every transmitting node.
