Photon-Emission-Guided Laser Fault Injection Enables RP2350 Secure Debug
Differential photon-emission microscopy localized debug enable register activity and narrowed the laser search before SWD-guided injection set the two bits required to restore Secure debug on an RP2350 A4.
Summary
A new method using differential photon-emission microscopy has improved the precision of laser fault injection in restoring secure debug functionality on the RP2350 A4. This technique enhances the debugging process by localizing register activity and reducing the search area for effective interventions.
