“In your garage or driveway sits a machine with more lines of code than a modern passenger jet. Today’s cars and trucks, with an internet link, can report the weather, pay for gas, find a parking spot, route around traffic jams and tune in to radio stations from around the world. Soon they’ll speak to one another, alert you to sales as you pass your favorite stores, and one day they’ll even drive themselves.
While consumers may love the features, hackers may love them even more.”
The New York Times, March 18, 2021
Hacking used to be an arcane worry, the concern of a few technical specialists. But with recent cyberattacks on pipelines, hospitals and retail systems, digital attacks have suddenly been thrust into public consciousness, leading many to wonder: are cars at risk, too?
Not if Marvell can help it. As a leading supplier of automotive silicon, the company has been intensely focused on identifying and securing potential vulnerabilities before they can remotely compromise a vehicle, its driver or passengers.
Unfortunately, hacking cars isn’t just theoretical – in 2015, researchers on a laptop commandeered a Jeep Cherokee 10 miles away, shutting off power, blasting the radio, turning on the AC and making the windshield wipers go berserk. And today, seven years later, millions more cars – including most new vehicles – are connected to the cloud.

Ethernet standards comprise a long list of features and solutions that have been developed over the years to resolve real network needs as well as resolve security threats. Now, developers of Ethernet In-Vehicle-Networks (IVN) can easily balance between functionality and cost by choosing the specific features they would like to have in their car’s network.
The roots of Ethernet technology began in 1973, when Bob Metcalfe, a researcher at Xerox Research Center (who later founded 3COM), wrote a memo entitled “Alto Ethernet,” which described how to connect computers over short-distance copper cable. With the explosion of PC-based Local Area Networks (LAN) in businesses and corporations in the 1980s, the growth of client/server LAN architectures continued, and Ethernet started to become the connectivity technology of choice for these networks. However, the Ethernet advancement that made it the most successful networking technology ever was when standardization efforts began for it under the IEEE 802.3 group.
