- Infineon introduced a 28nm automotive security controller with post-quantum cryptography support.
- The chip improves performance and enables secure applications such as eSIM, V2X communication, and vehicle access.
The Infineon TEGRION SLI22 automotive security controller was introduced on March 3 as a new generation hardware platform designed to protect connected vehicle systems from evolving cyber threats. Developed by Infineon, the controller targets security-critical automotive applications including eSIM connectivity, vehicle-to-everything communication, and digital car access solutions.
Security Architecture Built for Future Threats
The controller is manufactured using a 28nm process and is based on the Infineon Integrity Guard 32 architecture. It integrates post-quantum cryptography capabilities intended to address future security risks posed by advances in quantum computing.
Compliance and Certification
The platform has achieved Common Criteria certification from the German Federal Office for Information Security (BSI), supporting compliance with globally recognized automotive security standards. This certification strengthens trust for applications requiring secure authentication and encrypted communication.
Performance Enhancements for Connected Applications
The controller features an optimized cache architecture that improves processing performance by up to 25 percent compared with earlier solutions. Dedicated cryptographic accelerators support both classical encryption and emerging post-quantum algorithms, enabling stronger protection for connected vehicle environments.
Designed for Secure Automotive Ecosystems
According to Infineon, the TEGRION SLI22 platform is designed to enable secure deployment across multiple automotive domains including connected services, vehicle access management, and V2X communication systems. The device is currently available for sampling to automotive partners developing next-generation secure mobility platforms.
