Marvell switch secures automotive Gigabit Ethernet

Marvell Gigabit Ethernet switch for automotive

Marvell has announced a secure automotive Gigabit Ethernet switch, enabling safe data transmission in connected vehicles.

The automotive Ethernet switch is designed to prevent malicious attacks or compromises to the data streamed in and out of the vehicle.

There are hundreds of computing applications in the car that require a robust, secure in-vehicle-network, making Ethernet one of the technologies of choice for car makers. Adas and 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.

“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,” said Chris Koopmans, executive vice president at Marvell. “With our portfolio of wired and wireless automotive connectivity, Marvell is paving the way for secure, high-bandwidth data transmission in the car of the future.”

The switch has been purpose-built to address the increasing risk cybercrime represents to the automotive industry and is compliant with the IEEE802.3 and 802.1 standards. It uses a deep packet inspection engine and trusted boot functionality to ensure security at the foundational hardware layer. The switch also supports blacklisting and whitelisting addresses on all its Ethernet ports to enhance its security further.

To meet the standards of the industry and withstand harsh automotive environments, the switch is AEC-Q100 qualified. It supports 100Mbit/s and 1Gbit/s interfaces with five integrated 100baseT1 physical interfaces, and it can connect with Marvell’s previously announced 1000baseT1 phy.

Samples are available and are being evaluated by tier-one automotive suppliers.

“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 cyber attacks,” said Ian Riches at Strategy Analytics. “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 cyber crimes.”
