A growing number of applications in many fields today require satisfying reliability, safety, and security requirements. To be trustworthy, these applications must rely on integrated systems designed to satisfy these constraints. Furthermore, the most complex systems today are based on chiplets, interconnected in 2.5- or even 3-dimensional structures, which gives rise to new challenges. This thesis focuses on the design of optimized digital integrated systems in this context, capable of withstanding both disturbances (natural or intentional) and malicious attacks through eavesdropping on side channels (power consumption, direct electromagnetic emissions, coupled or conducted electromagnetic emissions, etc.). The mechanisms for protection against disturbances must therefore not increase the risk of malicious observation. Furthermore, it will be necessary to consider issues of inappropriate communication (transmission or reception) between chiplets, whether with a spying or attacking chiplet, or simply due to uncontrolled coupling effects that can create hidden telecom channels (or “screaming channels”). The usual electromagnetic compatibility constraints (emissivity, susceptibility) will therefore also need to be reconsidered in the proposed methodology.
