Infineon and Argus demonstrate cyber security solution for connected and automated cars; central gateway protection

At the VDI Kongress in Baden-Baden this week, Infineon Technologies AG and cyber security company Argus will an integrated cyber security solution for connected and autonomous vehicles. The system is based on an Infineon AURIX multicore microcontroller with the Intrusion Detection and Prevention System (IDPS) and remote cloud platform from Argus. At the heart of a vehicle’s central gateway, the cyber security solution protects the vehicle’s internal network from remote cyber-attacks.

The central gateway is crucial in the automotive security architecture. It interconnects all electronic control units (ECU) of in-vehicle domains, such as those used in the powertrain, driver assistance, chassis, as well as body and convenience control. The central gateway routes and controls the complete data communication between the ECUs. In addition, it is the central access point for software updates over the air (SOTA) and for diagnostics processes and maintenance updates via the On-Board Diagnostics (OBD) port.

With more connectivity embedded into a vehicle, the protection of critical system functions from cyber threats is paramount. The team-up of AURIX with Argus IDPS provides a major building block of that protection enabling automotive system suppliers to benefit from an enhanced cyber security solution.

The AURIX microcontrollers will be a key element in the vehicle’s central gateway. They control processes and handle monitoring and security tasks. In safety-related systems, AURIX microcontrollers support security protocols as well as the required security functions in hardware. Their built-in Hardware Security Module (HSM) protects in-vehicle software and data communication supporting highest security levels. These include security classifications up to EVITA “high” that is used to protect critical vehicle functions against a wide variety of attack scenarios; via direct cable access to the car network and via radio interface.

Thus, AURIX microcontrollers provide effective protection against hackers when trying to infiltrate the on-board systems. They offer up to six cores and best-in-class scalability in memory (up to 16 MB Flash, more than 6 MB on-chip SRAM) in combination with a rich feature set supporting latest connectivity, such as up to 12 CAN-FD channels, eMMC interface, and Ethernet functionality.

Argus developed its Intrusion Detection and Prevention System (IDPS) to specifically detect anomalous messages and prevent their propagation over the in-vehicle network in real-time.

As a high-performance, low-latency and small-footprint system, the IDPS uses context-aware heuristic and learning algorithms that enable optimal detection rate as a stand-alone solution. Combined with Argus Lifespan Protection, Argus’ remote cloud platform, it provides car manufacturers with situational awareness to their fleets’ cyber health via a cloud-based intuitive dashboard as well as with the means to analyze attacks and take preventive action. The IDPS supports different communication protocols, operating systems and deployment options.

Joining forces with Infineon is a natural next-step in ensuring that today's connected cars and the vehicles of the future are protected against cyber threats". Cyber security needs to be integrated into the entire design and manufacturing processes of vehicles. The Argus IDPS constitutes one significant protection layer out of our multi-layered solution suites for the automotive industry.
