Infineon and Argus come up with a cyber security solution for connected and automated car

Published: 20 October 2016

Real-time cyber security is key for the connected and automatecscd car. As cyber-attacks on vehicles should be mitigated in real-time, cyber security solutions must recognize malicious messages and prevent their propagation over the in-vehicle network. As cyber threats are dynamic in nature, cyber security solutions need to be updated over the air in order to help vehicle fleets stay immune to the latest threats and attack methods.

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.

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.

“With more connectivity embedded into a vehicle, the protection of critical system functions from cyber threats is paramount,” said Thomas Boehm, Senior Director, Chassis & ADAS Microcontrollers at Infineon. “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.”

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”, said Yoni Heilbronn, Vice President of Marketing at Argus Cyber Security. “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.”
