Abstract

Nowadays, microchips are used virtually everywhere, from simple home devices to confidential military equipment. In many scenarios, sensitive data is being processed by these devices. For example, in the case of electronic personal documents, fingerprints, facial images, and personal data are processed by the chip; and in some cases also iris images. Auditing proclaimed functions and a level of security of such microchips is becoming a valued service. In this doctoral thesis, we present an experimentally proven process for the microscopic analysis of chips, feasible in a low-cost setup. The described process was demonstrated on a chip acquired from the Czech biometric passport - from extracting the chip out of the plastic card up to analysis of the acquired microscopic images. We investigated and evaluated various potentially viable methods for logic element recognition; without the employment of machine-learning. Additionally, hardware-oriented attacks are discussed and followed by proposals for countermeasures leading to the hindering of microscopic analysis.
