Summary

\"LiDAR cyber security interference problem statement
When multiple active remote sensing systems such as LiDAR, radar, and ultrasound are present in the same environment they can interfere with one another. This multi‐camera scenario is a potential problem for cars. As the automotive industry extensively adopts active safety measures such as LiDAR, the possibilities for interference among sensors increase. Beside inadvertent interference due to the presence of multiple sensor systems, the multi‐camera scenario also addresses the issue of malicious attackers trying to inject wrong distance information into the active safety system. The safe use of highly automated vehicles requires a solution for the multi‐camera scenario.

Optical interference could be particularly a showstopper for the widespread adoption of low cost and \"\"flash\"\" LiDAR in multi‐user application fields such as automotive safety and autonomous vehicles. The large laser emission angle and field of view of flash LiDAR imagers make them especially vulnerable to optical interference.

Work performed

We analysed in detail the issues and mitigation approach for LiDAR cyber security laser interference suppression. We developed an optical interference suppression scheme that allows flash LiDAR imagers to run safely and reliably in uncontrolled environments where multiple LiDARs are expected to operate concurrently. This work illustrates how a Time‐Correlated Single‐Photon Counting LiDAR can control the timing of its laser emission to reduce its statistical correlation to other modulated or pulsed light sources. This method is based on a variable random delay applied to the laser pulse generated by the LiDAR, and to the internal circuitry measuring the Time‐of‐Flight.

- We manufactured a prototype demonstrator including a time of flight camera based on novel arrays of single photon detectors (SPADs) and verticla cavity emitting lasers (VCSELs). We performed an initial laboratory demonstration and characterization of the issues. Together with a SECREDAS partner NXP we advanced the design of a new detector to be manufactured in Q4\'2019 and demonstrated in later phase.
