Worlds first TPM for cybersecurity in the connected car

Munich, Germany - Oct 25, 2018 (PRN):

Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is enabling a crucial step toward greater cybersecurity in the connected car. The Munich-based company is the world’s first semiconductor manufacturer to put a Trusted Platform Module (TPM) specifically for automotive applications on the market. The new OPTIGA™ TPM 2.0 protects communication between the car manufacturer and the car which increasingly turns into a computer on wheels. A number of car manufacturers already designed in Infineon’s OPTIGA TPM.

The TPM is a hardware-based security solution that has proven its worth in IT security. By using it, car manufacturers can 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.

“As a computer on wheels, the connected car benefits from the experience of the IT industry,” said Martin Brunner, expert for automotive security at Infineon. “In the complex interplay between software, network and cloud, security hardware creates the solid foundation for secured communication. Backed by Infineon’s many years of expertise in the automotive and security areas, we have optimized the OPTIGA TPM for automotive applications. It is easy to integrate and substantially increases cybersecurity – from production to recycling of connected cars.”

Infineon has decades of experience in automotive electronics and hardware-based security. With the new OPTIGA TPM 2.0 and its AURIX™ family of microcontrollers, Infineon provides a comprehensive portfolio of application-specific security solutions that address key challenges in the automotive industry. At the first Infineon Automotive Cybersecurity Forum in Munich on 25 October 2018, experts from the automotive as well as security industry will discuss how to apply the expertise gained in other areas to connected cars.

Secured communication throughout the vehicle’s service life

Mobility of the future requires the exchange of huge volumes of data. Cars send real-time traffic information to the cloud or receive updates from the manufacturer “over the air”, for example to update software quickly and in a cost effective manner. The senders and recipients of that data, whether car makers or individual components in the car, require cryptographic security keys to authenticate themselves. These critical keys are particularly protected against logical and physical attacks in the OPTIGA TPM as if they were in a safe.

Furthermore, incorporating the first or initial key into the vehicle is a particularly sensitive moment for car makers. When the TPM is used, this step can be carried out in Infineon’s certified production environment. After that, the keys are protected against unauthorized access; there is no need for further special security precautions throughout the various stages of the – often globally distributed – value chain.

The TPM likewise generates, stores and administers further security keys for communication within the vehicle. And it is also used to detect faulty or manipulated software and components in the vehicle and initiate troubleshooting by the manufacturer in such a case.

Whereas a vehicle has an average service life time of 12 to 15 years, security features and algorithms keep on being developed and enhanced on a continuous basis. The TPM’s firmware can be updated by remote access so the security it offers can be kept up-to-date – including the cryptographic mechanisms (cryptoagility).

Technical information and availability

The new OPTIGA TPM 2.0 SLI 9670 from Infineon is a plug & play solution for automotive applications. It is especially suited for use in a central gateway, the telematics unit or the infotainment system of the vehicle.

The SLI 9670 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 can be integrated quickly and easily in the system thanks to the open source software stack (TSS stack) for the host processor, which is also provided by Infineon. 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. It is available now available and manufactured in security-certified production facilities of Infineon Germany and the Philippines. Further information is available at www.infineon.com/Auto-TPM
