Engineering tactile, immediate physical destruction switches to protect secrets during emergency evacuation or capture.
In extreme stress situations (such as aircraft ditching or hostile compound overrun), operators cannot navigate complex software menus to wipe secrets. PortableHSM features a recessed mechanical panic switch protected by a breakable safety cap, allowing operators to execute irreversible key destruction in a single, blind tactile motion.
Actuation of the panic switch trips internal crowbar circuits that dump stored capacitor energy across the volatile memory cells, destroying encryption keys in less than 50 nanoseconds, followed by high-current pulses that permanently vaporize internal silicon programming fuses.
