Security characterization of a RISC-V processor H/F H/F
Sujet de stage
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, devel-opment and innovation in four main areas: defense and security, nuclear and renewable energies, tech-nological research for industry, fundamental research in the physical sciences and life sciences. Drawing on its widely acknowledged expertise, the CEA actively participates in collaborative projects with a large number of academic and industrial partners. One of three institutes that comprise CEA Tech, the List institute is committed to technological innovation in digital systems. Within the DSCIN department of CEA List, the LECA and LFIM laboratories invest R&D efforts in the analysis of the robustness of embedded systems against fault-injection attacks.

Description de l'offre
With the rise of new development models based on open source, secure hardware components are increasingly being developed in public implementations, notably within the OpenHW Group [1]. The possibility of building a complete system from publicly available, open-source components is becoming a reality. For example, the CV32E40S RISC-V processor [2], derived from the CV32E40P [3], incorporates several hardware countermeasures against fault injection and side-channel attacks. However, a significant challenge lies in evaluating both the security level of each individual countermeasure and the overall effectiveness of these countermeasures when combined.
In [4], we introduced a method dedicated to the formal modeling and verification of microarchitecture-level fault injections and their effects on complex hardware/software systems. In the proposed internship, we are looking to apply this methodology to the CV32E40S processor, and to evaluate the potential security gap with regards to real hardware attacks. A security characterization of the CV32E40S will be performed using affordable fault injection equipment such as the ChipWhisperer fault injection tools [5].
The main tasks carried out in this internship will be :
- Implement the CV32E40S on an FPGA and functionally validate the attack setup using ChipWhisperer fault injection tools [5].
- Define attack scenarios and characterize vulnerabilities using the uArchiFI formal tool [4]
- Exploit the defined attack scenarios to perform a comprehensive security characterization of the CV32E40S using ChipWhisperer fault injection tools.

Profil du candidat
This position is aimed at students seeking an ambitious technical internship, eager to gain significant experience in industry-related technological research. It is particularly well-suited to students considering a doctorate, with new funded positions offered each year within the department. The internship is aimed at students in their final year of engineering school (or Master 2) in computer science or microelectronics, or equivalent levels, preferably with a specialization in processor systems/architecture or formal methods. Knowledge of micro-architecture or cybersecurity is an asset, but not a prerequisite. A strong capacity for personal work, ability to work in a team and motivation to take on technical challenges are essential.
In line with CEA's commitment to integrating people with disabilities, this job is open to all.
