The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

The Laboratory for Innovative Functions for Mixed-Signal Circuits (LFIM) is tasked with the study and design of digital and mixed-signal electronic circuits that meet requirements for energy efficiency, compact size, real-time operation, and operational reliability.
These circuits are applied in a wide range of systems and fields, such as high-performance computing architectures and low-power embedded systems—areas that now converge in the context of quantum computing, where a cryogenic environment imposes conflicting demands regarding performance and power dissipation.
The technologies developed within the laboratory leverage the latest advancements in nanoelectronics. The LFIM studies, designs, and integrates digital and mixed-signal processing architectures onto silicon to address application needs in areas including high-performance computing, the Internet of Things (IoT), radio-frequency (RF) circuits, and cyber-physical systems.

As an intern at the CEA, you will have the opportunity to work within a world-renowned research environment. Our teams consist of passionate and dedicated experts, providing an ideal setting for learning and collaboration. You will have access to state-of-the-art equipment and top-tier research resources to carry out your assignments. The work conducted may potentially lead to a scientific publication.
Laser fault injection (LFI) attacks pose a significant threat to security-critical embedded systems, enabling adversaries to manipulate processor behavior by inducing transient or permanent faults in integrated circuits. While post-silicon evaluations on fabricated devices provide concrete evidence of vulnerabilities, they are often costly, time-consuming, and difficult to interpret precisely. Conversely, pre-silicon security verification (e.g. using tools like μArchiFI [https://github.com/CEA-LIST/uArchiFI]) allows for systematic exploration of fault scenarios at the RTL or netlist levels but relies on abstract fault models that may not accurately reflect real-world physical attacks. This disconnect creates a methodological gap: experimental campaigns reveal actual fault effects [2], but their implications for design-time security assurance (e.g. wether a fault injection leads to a concrete vulnerability exploitation) needs further exploration [3].
The emergence of open-source hardware architectures, such as RISC-V-based processors, offers new opportunities to bridge this gap. When RTL descriptions, synthesized netlists, and physical layout information are available, it becomes possible to correlate experimental observations with microarchitectural behavior. Existing fabricated test chips, already available in the lab in advanced technologies [4] (e.g., 22nm FD-SOI or 28nm CMOS), further enable the validation of fault models under realistic conditions. However, existing approaches lack a systematic methodology to translate experimental data into physically grounded fault models that can be effectively used in pre-silicon verification.
What do we expect from you?
The long-term objective is to develop a bottom-up methodology for deriving and validating pre-silicon fault models from laser fault injection campaigns. This internship will focus on bridging the gap between RTL-level fault analysis, enriched with layout-level information, and results of fault injection campaigns. This work may lead to the design of new fault models derived from experimental observations and physical design information. By integrating these refined models into tools like μArchiFI, the internship will contribute to improving the accuracy and traceability of pre-silicon security assessments, ultimately supporting the development of more robust processors.

The CEA is the French Alternative Energies and Atomic Energy Commission ("Commissariat à l'énergie atomique et aux énergies alternatives"). It is a public body established in October 1945 by General de Gaulle. A leader in research, development and innovation, the CEA mission statement has two main objectives: To become the leading technological research organization in Europe and to ensure that the nuclear deterrent remains effective in the future.
The CEA is active in four main areas: low-carbon energies, defense and security, information technologies and health technologies. In each of these fields, the CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research.
The civilian programs of the CEA received 49% of their funding from the French government, and 30% from external sources (partner companies and the European Union).
The CEA had a budget of 4,3 billion euros.
The CEA is based in ten research centers in France, each specializing in specific fields. The laboratories are located in the Paris region, the Rhône-Alpes, the Rhône valley, the Provence-Alpes-Côte d'Azur region, Aquitaine, Central France and Burgundy. The CEA benefits from the strong regional identities of these laboratories and the partnerships forged with other research centers, local authorities and universities.
