Hundreds of computing applications in next-gen car require a robust, secure in-vehicle-network, making Ethernet the technology of choice for auto manufacturers. Advanced driver assist systems (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 new automotive Ethernet switch is designed to prevent malicious attacks or compromises to the data streamed in-and-out of the vehicle. Such security features are indispensable to ensure the safety of the vehicle and its occupants.  

Marvell says its gigabit Ethernet switch has been purpose-built to address the risk cybercrime represents to the automotive industry. The device and is  compliant with the IEEE802.3 and 802.1 standards. The solution employs a deep packet inspection (DPI) engine and trusted boot functionality to ensure 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 enhance its security. To meet the standards of the industry and withstand harsh automotive environments, the 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 one automotive suppliers.
