TPM maintains up-to-date security for the end of the vehicle's lifespan
Suitable for use with SLI 9670, central gateways, etc.
Common Criteria, AEC-Q100 certification obtained
On the 30th, Infineon Technologies launched a Trusted Platform Module (TPM) product for automobiles that enhances the cybersecurity of connected cars. The new OPTIGA TPM 2.0 protects communications between automakers and vehicles that are now transforming into computers on wheels. Several automakers have already adopted Infineon's OPTIGA TPM.

TPM is a proven hardware-based security solution in the field of IT security. By using TPM, sensitive security keys used for access authorization, authentication, and data encryption can be handled securely. Additionally, since TPM can be updated, security can be kept up-to-date throughout the vehicle's service life.

Martin Brunner, an automotive security expert at Infineon, stated, “As computers on wheels, connected cars can leverage experience gained in the IT field.” “As software, networks, and the cloud interact in a complex manner, security hardware provides a robust foundation for secure communication,” he said. “Based on Infineon’s years of expertise in the automotive and security sectors, we are now offering the OPTIGA TPM optimized for automotive applications. This product can be easily integrated into vehicles and significantly enhances cybersecurity throughout the entire process of connected cars, from production to recycling.”

The new OPTIGA TPM 2.0 and AURIX microcontroller family provide a comprehensive security solution that meets all major application requirements for automotive use.

Infineon's new OPTIGA TPM 2.0 product, the SLI 9670, is a plug-and-play solution for automotive applications. It is particularly suitable for use in central gateways, telematics units, and infotainment systems.

The SLI 9670 consists of a security chip robust against attacks and high-performance firmware developed in compliance with the latest security standards. This firmware enables immediate use of security functions such as encryption, decryption, signing, and verification. Furthermore, by adopting an open-source software stack (TSS stack) for the host processor, it can be easily and quickly integrated into a system. It also features an SPI interface, an extended temperature range of -40°C to 105°C, and advanced cryptographic algorithms such as RSA-2048, ECC-256, and SHA-256.

This new TPM product meets the internationally recognized Trusted Computing Group's TPM 2.0 standard and has obtained Common Criteria certification for security and AEC-Q100 automotive standard certification. Mass production has now begun, and it is manufactured at Infineon's certified production facilities in Germany and the Philippines.
