TPM for cybersecurity in the connected car
Infineon Technologies AG introduced its Trusted Platform Module (TPM) specifically for automotive applications. The Optiga TPM 2.0 is designed to protect communication between the car manufacturer and the car.
The TPM is a hardware-based security solution that enables car manufacturers to incorporate sensitive security keys for assigning access rights, authentication, and data encryption in the car in a protected way. The TPM can also be updated so that the level of security can be kept up to date throughout the vehicle’s service life.
Infineon’s Optiga TPM 2.0 SLI 9670 is a plug & play solution for automotive applications. It is designed for use in a central gateway, the telematics unit, or the infotainment system of the vehicle. It consists of an attack-resistant security chip and high-performance firmware developed in accordance with the latest security standard. The firmware enables immediate use of security features, such as encryption, decryption, signing, and verification. The TPM is designed for quick and easy integration into the system due to the open source software stack (TSS stack) for the host processor. It has an SPI interface, an extended temperature range from -40°C to 105°C, and the advanced encryption algorithms RSA-2048, ECC-256, and SHA-256.
The new TPM complies with the internationally acknowledged Trusted Computing Group TPM 2.0 standard, is certified for security according to Common Criteria, and is qualified in accordance with the automotive standard AEC-Q100.
