Their announcement comes at a time when vehicular connectivity is growing rapidly. This provides many opportunities to enable new and innovative vehicle features, but it also increases the potential for cyber-attacks on vehicle networks.
Therefore, car manufacturers and suppliers must take appropriate security measures to ensure the safety of vehicles and passengers.
In response, Vector's AUTOSAR Classic embedded software MICROSAR Classic now supports Infineon's AURIX TC4x microcontroller (MCU) family, which complies with the latest cybersecurity and safety standards ISO/SAE 21434 and ISO 26262. .
The security concept eliminates performance bottlenecks in fast and secure communications and supports post-quantum cryptography.
All AURIX TC4x MCUs are equipped with a Cyber Security Real-Time Module (CSRM) with dedicated memory and a Cyber Security Satellite (CSS) that provides accelerators for cryptographic services that can run in parallel.
Vector's MICROSAR HSM supports hardware-accelerated computation of cryptographic operations with CSS. The Crypto Satellite is addressed directly by the MICROSAR Classic Crypto driver on the host CPU, maximizing throughput and helping to eliminate delays caused by inter-process communication with the Cyber Security Satellite.
Key management between CSS and CSRM is performed by firmware MICROSAR HSM, and this architecture enables significant performance improvements compared to traditional cryptographic hardware acceleration in HSM.
“With Crypto Satellite, Infineon offers an elegant and powerful solution. Thanks to good and close cooperation, we were able to implement the firmware for CSS at an early stage. This has already been demonstrated in a prototype project. ” said Matthias Traub. , Director of Embedded Software and Systems at Vector.
“Vector's tools offer great advantages to engineers, allowing them to simplify and manage difficult and highly complex subject areas. and quality,” added Lars Wemme, Senior Vice President, ADAS, Chassis and EE Architecture at Infineon.
With the new cybersecurity concept of the AURIX TC4x, Infineon will be able to secure its future by supporting, for example, SOTA (Software over the Air) application scenarios that require fast, safe and secure distribution of software updates from the cloud and from within the cloud. can meet the requirements of Software-Defined Vehicles. In-vehicle network.
The new security cluster also provides communication protocols with authentication and authenticated encryption, which will become increasingly important in future platforms.
