Infineon SLI9670AQ20FW1311XUMA1: The Automotive Security Controller Powering Next-Generation Secure Vehicle Access Systems

The evolution of vehicle access systems from traditional physical keys to passive keyless entry (PKE) and smart phone-based solutions has revolutionized the user experience. However, this convenience introduces significant vulnerabilities, making robust cybersecurity a non-negotiable priority. At the heart of defending against these threats is the Infineon SLI9670AQ20FW1311XUMA1, a dedicated automotive security controller designed to be the trusted anchor for secure access.

This hardware-based security controller is engineered to meet the stringent demands of the automotive industry. It provides a secure, isolated environment for storing cryptographic keys and executing sensitive operations, shielding them from software attacks and physical tampering. The chip is built upon a high-performance 32-bit ARM® SC300 secure core, which is Common Criteria EAL6+ certified, one of the highest assurance levels available for commercial security chips. This certification underscores its resilience against sophisticated attacks.

A key application for the SLI9670 is in digital car keys, enabling features like passive entry and start (PASE) and secure sharing of virtual keys via mobile devices. It supports multiple digital key standards, including the CCC (Car Connectivity Consortium) Digital Key specification, ensuring interoperability across different vehicle brands and smartphone manufacturers. Its hardware-based crypto accelerators ensure that cryptographic functions like AES, SHA, and ECC are performed with both high speed and maximum security, preventing relay attacks and key cloning.

Furthermore, its AEC-Q100 Grade 2 qualification guarantees reliable operation in the harsh automotive environment, withstanding extreme temperatures and vibrations. The integration of this controller allows automotive OEMs to create systems that are not only convenient but also fundamentally secure by design, protecting the vehicle and user data from the ever-evolving landscape of cyber threats.

ICGOOODFIND: The Infineon SLI9670AQ20FW1311XUMA1 is an industry-leading automotive security controller that provides a hardware-rooted trust anchor for next-generation digital key systems. Its Common Criteria EAL6+ certification and compliance with CCC Digital Key standards make it a critical component for OEMs building secure, convenient, and reliable vehicle access solutions.
