New Launch in Automotive Security

Infineon Technologies AG has introduced the 28nm TEGRION™ SLI22, a cutting-edge automotive security controller aimed at enhancing the security of connected systems. The device has received Common Criteria (CC) certification from the German Federal Office for Information Security (BSI) and integrates post-quantum cryptography (PQC), positioning it as a solution to counteract emerging cyber threats posed by advancements in quantum computing.

The SLI22 is versatile, making it suitable for various security-critical applications such as eSIM, vehicle-to-everything (V2X) communications, and car access systems. This new addition complements Infineon’s established lineup, which includes the SLI37 and SLI97 products, thereby solidifying the company’s reputation in the automotive security domain. The device is built on the advanced Infineon Integrity Guard 32 architecture, ensuring robust protection for system integrity and reliability. Significantly, the new ETSI MFF3 package design reduces space requirements by 70 percent compared to previous models.

Tolgahan Yildiz, Head of the Trusted Mobile Connectivity and Transactions Product Line at Infineon, emphasized that the company’s long history in automotive security enables it to offer scalable solutions that meet the highest safety standards. Infineon’s dedication to innovation aims to proactively address potential threats while maintaining a strong legacy of customer trust and satisfaction.

Infineon stands out in the PQC field, being the first to offer hardware-based solutions that implement PQC algorithms. The SLI22 is notable for being part of the TEGRION family with the world’s first Common Criteria EAL6+ certification specifically designed for a security controller featuring PQC algorithms. The device’s 32-bit CPU, based on Arm® v8-M architecture, combines exceptional speed with energy efficiency. An optimized cache enhances performance by up to 25 percent, paired with cryptographic accelerators that support both traditional and post-quantum algorithms, ensuring comprehensive protection.

Additionally, the SLI22 has been designed for long-term reliability, offering a 17-year data retention capability, which is crucial for vehicles and equipment that remain operational in the field for extended durations.

The TEGRION SLI22 automotive security controller is currently available for sampling. For further details, visit the official Infineon webpage. Moreover, Infineon will showcase its products focused on decarbonization and digitalization at the embedded world event in Nuremberg, Germany, from March 10-12, 2026.
