Specialist in infrastructure semiconductor solutions, Marvell, together with ESCRYPT are offering a joint solution to secure Ethernet-based in-vehicle communication. The Marvell 88Q5050 automotive secure switch integrates ESCRYPT‘s CycurGATE firewall and intrusion detection system to provide an enhanced level of end-to-end security to the automotive customers.

The Marvell 88Q5050 is an automotive Ethernet Gigabit switch with cutting-edge security features to prevent malicious attacks or compromises to the data streamed in the vehicle. This advanced switch employs deep packet inspection (DPI) techniques and Trusted Boot functionality to deliver extraordinary security in automotive Ethernet networks. The switch supports both blacklisting and whitelisting addresses on all of its Ethernet ports to further enhance its security.

If used as an integrated component of the switch, ESCRYPT’s CycurGATE automotive firewall will support all filter mechanisms inside the Marvell 88Q5050 Ethernet switch: stateless packet inspection, dynamic stateful inspection, and deep packet inspection. The entire packet flow is monitored and managed centrally, with no resulting interference with the host controller of the individual ECUs.

The firewall supports all standard routing schemes and can be used on the switch either as a library or as a standalone solution. CycurGATE makes the most of the hardware acceleration on the switch. The switch hardware and software are algorithmically so interwoven that the firewall can process the majority of data packets at wire speed.

The Marvell 88Q5050 Ethernet switch is also available with ESCRYPT’s integrated intrusion detection system. The intrusion detection system is an embedded security component that monitors in-vehicle communication so it can detect anomalies, typical intrusion signatures, and abuse of diagnostic mechanisms.

“We are excited to partner with ESCRYPT to bring a comprehensive solution for a multi-layered cyber security protection for vehicles to not only detect but take rapid action to ensure the safety of the vehicle occupants and the surrounding road users,” said Jyotsna Chitri, Sr. Product Manager of Automotive Networking Products, Marvell Semiconductor.

ESCRYPT Product Manager Siddharth Shukla, added: “Together with Marvell, we offer our customers a complete solution to secure in-vehicle Ethernet networks. This solution provides comprehensive protection against unauthorised access and ensures security of onboard communication from the switch – virtually right out of the warehouse.”
