As the importance of security in vehicle electrical systems grows, Infineon Technologies is entering the market by introducing a next-generation automotive security controller.

Infineon unveiled the TEGRION™ SLI22, manufactured using a 28nm process, on the 9th and presented security technology to prepare for the era of advanced cyber threats and quantum computing.

The SLI22 has been certified as a Common Criteria EAL6+ product by the German Federal Office for Information Security (BSI), an international security evaluation standard, and has been verified for its high level of reliability and safety.

In particular, we respond to long-term security needs by applying quantum-resistant cryptography (PQC), which can protect existing encryption systems even in a quantum computer environment.

This security controller is designed for use in a variety of security-critical automotive applications, including eSIM, vehicle-to-everything (V2X) communication, and vehicle access control systems.

Within Infineon's security solution ecosystem, it expands its portfolio alongside the existing SLI37 and SLI97 product families, further strengthening its competitiveness in the automotive security market.

SLI22 is based on Infineon's Integrity Guard 32 architecture, which enhances system integrity and data protection.

In addition, the new ETSI MFF3 package has been applied to significantly reduce the installation area compared to the existing package. This allows for flexible design even in vehicle electrical environments with significant space constraints.

There have also been improvements in performance.

Equipped with a 32-bit processor based on Arm v8-M, it simultaneously secures high computational performance and power efficiency, and improves processing speed through cache structure optimization.

It reduces the burden of security computation by incorporating dedicated hardware that accelerates not only existing encryption algorithms but also post-quantum cryptographic operations.

Durability has also been enhanced to take into account the characteristics of being installed in vehicles for long periods of time.

The design allows data retention for up to 17 years, ensuring stable security performance throughout the vehicle life cycle.

Infineon's strategy with this product is to proactively provide high-reliability security technology required in future mobility environments.
