Abstract
Nowadays, most of the sectors in the industry rely on the use of electronic circuits and systems. Among these systems and integrated circuits, there are circuits dedicated to security, such as smart cards, which usage has been generalized over the past decade. They are now indeed used in numerous fields, such as finance, public health or public transportation to name only a few. The data they handle and process are very valuable and can be desired. Therefore, it is important to ensure the reliability and the security of those systems against malicious attackers. That is why it is necessary to adapt the security characterization tools, especially if we consider the constant evolution of technologies and threats. In this context, my PhD focused on the development of platforms dedicated to electromagnetic attacks, and more particularly on two main points:- The enhancement of the spatial resolution of electromagnetic analysis probes thanks to an advanced flexible electronic technology paired with 3D printing, but also thanks to the design of a low noise and wide band amplifier in CMOS 0.35µm technology.- The enhancement of both timing and spatial resolution of electromagnetic fault injection platforms, here as well, by exploiting the advanced flexible electronic technology and 3D printing, but also thanks to the development of simple electronic modules.All those modules, allowing the improvement of the platforms, were developed, validated and characterized. Their exploitability for hardware cryptanalysis purposes was also experimentally demonstrated.
