So far connected objects have been designed and deployed with strong cost and power consumption constraints, postponing security to secondary requirements. Recent successful attacks have proved that the security of IoT will become a major and crucial issue and technical solutions, like LightWeight Cryptographic (LWC) and countermeasures against physical attacks, have to be designed to bridge the gap between security needs and cost constraints.
Current algorithms are mainly designed thanks to CMOS circuits. These algorithms have to be securely implemented in order to face physical attacks (side-channel analysis or perturbation-based attacks), but the proposed countermeasures are power consuming. Then, technology is expected to bring the next innovation to tackle this challenge.
MISTRAL project, founded by the French Research Agency (ANR) and leaded by Ecole des Mines de Saint-Etienne (Gardanne), CEA-Tech PACA (Gardanne), Institute Material Microelectronics and nanoscience of Provence IM2NP (Marseille) and CNRS-Spintec (Grenoble), aims at securing LWC algorithms by hybridizing MRAM memories with CMOS circuits at lowest energetic impact.
The goal of his work is the advanced study of MRAM memory cells, before and after physical attack (LASER or electromagnetic)
The study will be divided into three parts:
• Advanced electrical characterization of MRAM cells, performed on wafers with probe stations, in order to better understand their electrical characteristics (resistance values before and after writing, writing currents and voltages), before and after physical attack (LASER or electromagnetic).
• Electrical compact modeling of MRAM cell, developed for design, integrating the effect of an external physical attack to optimize, as soon as possible in design, the robustness of an elementary memory cell.
• Simulation (physic COMSOL modeling or internal C code) of the multitude of layers in the MRAM stack, to predict the thermal effect of a physical attack to anticipate the robustness of the elementary memory cell.
This work will be coordinated with another thesis work in the MISTRAL project.
