Nanofocused X-ray beam to reprogram secure circuits


Synchrotron X-ray nano-beamlines is investigated as a tool to perturb microcontroller circuits. This technique is used to target the Flash, EEPROM and RAM memory of a circuit. The obtained results are very promising and show that it is possible to corrupt a single transistor in a semi-permanent state. A simple heat treatment can remove the induce effect, thus making the corruption reversible. A concrete attack on a code stored in Flash is demonstrated.
