Soitec and CEA Join Forces for Automotive Cybersecurity
As vehicles evolve into more sophisticated machines with a high reliance on software and connectivity, ensuring robust cybersecurity is vital. The intricate systems within modern cars, often containing over 100 microcontrollers, may present vulnerabilities that can be exploited by remote hackers. In pursuit of addressing these challenges, Soitec and CEA have embarked on a collaborative effort to leverage Fully Depleted Silicon-on-Insulator (FD-SOI) technology to enhance cybersecurity measures.
The Increasing Need for Security in the Automotive Industry
The automotive landscape is rapidly changing as cars become increasingly connected and autonomous. With this transformation comes the responsibility to protect these vehicles from an array of cyber threats. Fault injection attacks, a notable risk identified by the automotive cybersecurity standards ISO/SAE 21434, can severely compromise vehicle security by manipulating the normal operation of microcontrollers. This challenge necessitates innovative solutions to safeguard against potential breaches.
Understanding Fault Injection Attacks
Fault injection attacks occur when a malicious actor intentionally disrupts the normal functioning of a microcontroller through methods such as applying voltage surges or using laser pulses. This manipulation, even for brief moments, can lead to unauthorized actions including bypassing security protocols or accessing sensitive data. Techniques like Laser Fault Injection (LFI) exploit chip vulnerabilities, allowing attackers to inject faults at incredibly precise scales that can have devastating effects on vehicles.
Advantages of FD-SOI Technology
Traditionally, bulk silicon substrates have been susceptible to such sophisticated attacks. However, FD-SOI technology provides a layer of protection due to its unique architecture. With a buried oxide layer, this innovation effectively isolates the active film from the substrate, mitigating most physical fault injection vulnerabilities. Collaborative research between Soitec and CEA-Leti has shown that FD-SOI substrates considerably increase the difficulty of inducing faults compared to bulk silicon substrates.
Research Findings and Industry Compliance
In comparative tests, the FD-SOI substrate showed a remarkable resilience against fault injection, requiring significantly more power and effort to compromise its functionality. This enhanced capability aligns with the new and evolving automotive cybersecurity standards, which call for fortified security measures, including a secure reference chip to protect vehicle software encryption codes. FD-SOI is establishing itself as the preferred platform for such applications.
Future Innovations in Semiconductor Security
The ongoing advancements in semiconductor technology suggest even more exciting developments on the horizon. Innovations such as buried optical barriers, integrated sensors, and Physical Unclonable Functions (PUFs) could redefine semiconductor wafers, turning them into active security perimeters for automotive applications.
Industry Insights from Leaders
Christophe Maleville, Chief Technology Officer at Soitec, emphasized the critical role of substrate engineering in cybersecurity efforts. He noted, "This study demonstrates how substrate engineering itself can be a security enabler. FD-SOI extends Soitec's differentiation into the domain of hardware trust, paving the way for wafers that actively contribute to cybersecurity." Sébastien Dauvé, the Chief Executive Officer of CEA-Leti, added, "Our collaboration on FD-SOI bridges advanced research and industrial application, proving that scientific insight can directly translate into safer automotive electronics — a cornerstone of Europe's strategic autonomy in secure semiconductors."
Significance of Collaboration and Future Outcomes
The research efforts detailed above are a part of the FAMES Pilot Line of the Chips Joint Undertaking, demonstrating a strong commitment to advancing innovation while ensuring the security of automotive technologies. As the industry gears up for an exciting future filled with autonomous vehicles and enhanced connectivity, securing this technology is paramount for manufacturers and consumers alike.
