Infineon & Vector collaborate for enhanced automotive cybersecurity

Munich, Germany – 12 April 2024 – Infineon, a company that designs and manufactures semiconductors, especially those used in the automotive industry for safety and efficiency, and Vector, a German company that develops software tools and components for secure networking of electronic systems in the automotive industry, collaborate to enhance automotive cybersecurity. Vector’s AUTOSAR Classic embedded software MICROSAR Classic supports Infineon’s new AURIX™ TC4x microcontroller (MCU) family. The growing connectivity of vehicles presents opportunities for new automotive functionalities. Simultaneously, the risk of cyber-attacks on vehicle networks is rising. It is essential for car manufacturers and suppliers to implement security measures to ensure vehicle and passenger safety.

The AURIX TC4x family is compliant to the latest cybersecurity and safety standards ISO/SAE 21434 and ISO 26262.The security concept eliminates performance bottlenecks in fast and secured communication and supports post-quantum cryptography. All AURIX TC4x MCUs are equipped with a Cyber Security Realtime Module (CSRM) with dedicated memory as well as a Cyber Security Satellite (CSS). The CSS accelerators provide cryptographic services that can execute in parallel. Vector’s firmware MICROSAR HSM supports the hardware-accelerated calculation of crypto operations by the CSS. The host CPU directly addresses the Crypto Satellite through a MICROSAR Classic Crypto driver, maximizing throughput and eliminating delays introduced by inter-process communication with the cybersecurity satellite. Firmware MICROSAR HSM performs key management between the CSS and the CSRM. This architecture enables a significant performance increase compared to conventional crypto hardware acceleration in HSMs.

“With the Crypto Satellite, Infineon offers a sophisticated and powerful solution. Thanks to the good and close cooperation, we were able to implement the firmware for the CSS at an early stage, which has already proven itself in prototype projects”, said Matthias Traub, Director of the Embedded Software and Systems department at Vector.

“Vector’s tools equip engineers with a significant advantage, enabling them to simplify and manage challenging and highly complex subject areas. Together with our MCUs, Vector and Infineon enable customers to achieve highest reliability and quality”, said Lars Wemme, Senior Vice President ADAS, Chassis & EE-Architecture at Infineon. “We look forward to a continued close partnership with our new AURIX TC4x generation.”

With the new cyber security concept of AURIX TC4x, Infineon meets the requirements of future software-defined vehicles. For example, it supports SOTA (Software over the air) application scenarios that require fast, safe, and secured distribution of software updates from the cloud and within the in-vehicle network. The new security cluster serves communication protocols with authentication. Authenticated encryption is also included, which is gaining importance in future platforms.
