Gigabit Ethernet Switch Protects Connected Car From Cyberthreats


Marvell has launched an automotive gigabit Ethernet switch optimised for autonomous and connected vehicles. The switch has advanced security features to prevent malicious attacks or compromises to the data streamed in-and-out of the vehicle.

The new Ethernet switch can address the increasing risk cybercrime represents to the automotive industry and is fully compliant with the IEEE802.3 and 802.1 standards.

“As connected cars become more autonomous and the demand for greater data volume and mobility continues to rise, vehicles are also becoming increasingly vulnerable to security breaches and new types of cyberattacks. Marvell’s new generation of secure automotive gigabit Ethernet switches constitute a secure hardware foundation for connected cars that will help safeguard the intelligent infrastructures with advanced security features against next level cybercrimes,” said Ian Riches at Strategy Analytics.

In terms of security, the product employs a deep packet inspection (DPI) engine and trusted boot functionality. This ensures a robust level of security at the foundational hardware layer. The switch also supports both blacklisting and whitelisting addresses on all its Ethernet ports to further enhance its security.

The firm noted that Ethernet is the technology of choice for auto manufacturers as there are hundreds of computing applications in the car that require a robust, secure in-vehicle-network. Advanced driver assist systems (ADAS), in-vehicle infotainment (IVI), as well as autonomous vehicles, will rely on digital information streamed internally within the vehicle and externally from the vehicle to other vehicles.

Chris Koopmans, executive vice president, Networking and Connectivity Group, at Marvell said: “The automotive industry is going through one of the most dramatic transformations in its history, driven by disruptive trends such as assisted and autonomous driving, electrification, and the connected car. With our portfolio of wired and wireless automotive connectivity solutions, Marvell is paving the way for secure, high-bandwidth data transmission in the car of the future.”

Autonomous Vehicle API For LIDAR & RADAR

To meet the rigorous standards of the industry and withstand harsh automotive environments, the new Ethernet switch is AEC-Q100 qualified. It supports both 100Mbps and 1Gbps interfaces with five integrated 100BASE-T1 physical interfaces and can connect with Marvell’s previously announced 1000BASE-T1 PHY.

Samples are available and are being evaluated by leading tier 1 automotive suppliers.
