The research unit Secure Systems and Architectures (SAS) is a joint team between CEA and École des Mines de Saint-Étienne. It is dedicated to the design and testing of secure circuits, contributing to the development of communicating solutions.
Mission and Focus
The main mission of the SAS department is to guarantee the integrity of electronic components and the data they contain, such as cryptographic keys, software, intellectual property blocks, and in-memory data, against fraudulent manipulations commonly referred to as “attacks”.
Main Missions
- Modeling of Physical Phenomena Related to Attacks
Through experiments conducted on state-of-the-art equipment, such as current consumption analysis benches and laser or electromagnetic pulse fault injection benches, the department precisely models the physical phenomena enabling these attacks. - Design of Effective Protections
The developed models are used to design protections, with the most effective ones being integrated into design flows according to the “secure by design” method.
Strategic Challenges
- Proactive Security
Anticipating threats as early as possible and in various forms, in a context where security is a permanent race between attackers and defenders. - System Robustness
Developing communicating solutions through the design and testing of secure circuits, contributing to robustness against attacks.
Key Contributions
The SAS department is involved in various collaborative projects and partnerships aimed at strengthening the security of electronic systems.
Collaborative Projects
- FQS Project
This project aims to design, develop, and validate a secure hardware architecture for the MCU component and its I/O peripherals of the SP3H system. - GESTE Project
The objective is to propose a certification methodology adapted to the payment terminal market and to demonstrate the feasibility of a terminal meeting SEPA security requirements.
Partnerships
The SAS department collaborates with various industrial and academic stakeholders to strengthen the security of electronic systems.
Priority Research Themes
- Securing Embedded Systems and IoT
Study of vulnerabilities and development of countermeasures for connected devices. - Design of Resilient Architectures for Critical Infrastructures
Development of solutions to ensure continuity of operations in case of attacks or failures. - Cryptography and Protection of Sensitive Data
Implementation of advanced cryptographic mechanisms to protect confidential information. - Security Evaluation and Certification
Development of methodologies to evaluate and certify the security of electronic systems.
