ESCRYPT and Marvell are offering a joint solution to secure Ethernet-based in-vehicle communication. The Marvell 8Q5050 automotive secure switch integrates ESCRYPT‘s CycurGATE firewall and intrusion detection system to provide an enhanced level of end-to-end security to automotive customers.

The Marvell 88Q5050 is an automotive Ethernet Gigabit switch with advanced 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 high 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, according to the company. The firewall supports all standard routing schemes and can be used on the switch either as a library or as a standalone solution. The switch hardware and software are algorithmically interwoven so that the firewall can process most 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.
