Security and Safety of Unmanned Aerial Vehicles

Joined the innovation department at NXP to work on cutting-edge drone research projects. The research was about the security and safety of unmanned aerial vehicles. I already had solid experience in automotive security, and I worked with a team of more than 14 people from the Netherlands, Germany, and the US. Every team member was assigned to research topics. I was assigned three topics during that period.

I oversaw the full development lifecycle, from requirements and architecture to the implementation of a proof of concept for each. Two topics were safety-related—redundant networking and dual battery management system. The security topic was related to flight registration and drone registration architecture.

Designed and implemented the two safety topics and showcased the feasibility of the concepts. In the drone security concept, I used my previous experience with VW to define an architecture for drone and flight registration protocol based on the NXP security chip, SE050. I integrated plug and trust firmware (SE050 interfacing library) to the PX4 open source to showcase the proposed protocol.

Security Software Layer for Telematics Unit

I worked on the telematics unit of VW ID.3 and ID.4 to design and implement access control security layers between the vehicle and the cloud in addition to the security layer within the vehicle. Developed the secure coding software architecture and threat modeling. I also took a product owner role in a scaled agile environment during this period.
