The Ethernet Security Hub, a solution for connected and autonomous vehicles equipped with Ethernet networks

Arilou Information Security Technologies, a supplier of cyber security solutions for the automotive industry, has developed a central management technology to enable control of in-vehicle communication networks. Specifically, Arilou, part of the NNG Group, designed this cyber security tool – the Ethernet Security Hub – as a solution for connected and autonomous vehicles equipped with Ethernet networks.

Ethernet networks are increasingly being incorporated in vehicles to efficiently and reliably process the vast amount of data from complex new electronic systems, such as advanced driver assistance systems (ADAS) and infotainment systems. Compared to CAN bus networks that have traditionally been used, Ethernets have a greater bandwidth to collect and transfer more data at a faster rate. Arilou’s technology was developed to prevent security risks, and addresses critical safety vulnerabilities associated with integrating connected and automated systems into vehicles.

Arilou’s Ethernet Security Hub allows for complete, real-time management of the interaction between a vehicle’s electronic systems. It acts as a translator to bridge gaps between various systems and allow them to communicate with each other in a secure fashion, even if they were not originally intended to do so.

The technology works by opening and closing secured communication channels between components in an ad-hoc manner, thus ensuring that the highest level of security is always kept. This helps limit the number of areas vulnerable to attacks from hackers.

With the innovative new solution, a GPS transmitter that used to constantly transmit a vehicle’s location over the cloud can now be programmed to only send location information when an accident occurs for added safety and driver privacy.

In addition, while reducing the risk of an attack to the in-vehicle communication systems, the security solution does not interfere with the overall functionality of the Ethernet network.

The Ethernet Security Hub is flexible and can be configured to fit the individual system architectures of any OEM vehicle. New electronic components can easily be added if automakers change suppliers or new technologies are introduced. This flexibility makes it a solution for heavy-duty trucks and buses, and other modes of transportation, such as trains, and in some cases, ships and airplanes.
