Detecting Memory Bit-Flips and Unauthorized Code Modifications in the Field

Periodic remote cryptographic attestation verifying firmware code integrity in deployed devices.

Cosmic Ray Bit-Flip Detection

Single-event upsets (SEUs) can flip bits in flash memory, causing subtle calculation errors in radiation therapy dosages. Continuous runtime hash checks verify code integrity.

Zero-Downtime Cryptographic Validation

Cryptographic checksums execute in background low-priority RTOS threads without interrupting vital patient monitoring tasks or sensor polling cycles.

SHA-256 periodic flash integrity verification on all active nodes
Instant safe-state transition if unexpected firmware mutations are detected
Cryptographic proof logs exported to regulatory surveillance portals
