Engineering rapid key destruction mechanisms for radios deployed in combat zones subject to physical overrun.
Tactical radios deployed in contested environments can fall into enemy hands. RadioHSM provides multiple zeroization mechanisms: an external emergency push-button, software panic commands received over the air, and autonomous tamper sensors that detect casing breach or unauthorized disassembly.
Upon zeroization activation, high-speed discharge circuits pull all volatile key registers to ground in less than 100 nanoseconds, while localized electrical overstress pulses permanently blow on-chip configuration fuses, preventing laboratory forensic reconstruction.
