Recent developments by NIST and the global race for a Cryptographically Relevent Quantum Computer (CRQC) have led to an increased interest in the integration of Post Quantum secure cryptographic algorithms to traditional applications. Despite this interest, there has been relatively limited work in integrating these PQ secure algorithms to industrial/robotics applications on constrained IoT devices. The existing efforts often lack comprehensive implementation, with partial integrations that fail to fully address the application’s security vulnerabilities against quantum adversaries. This work aims to fill this gap by fully equipping the communication middleware DDS (Data Distribution Service) of ROS 2 with the NIST standardized cryptographic algorithms. We also present the performance analysis of these PQ secure algorithms on a constrained device and compare these results highlighting the feasibility of running PQ secure cryptographic algorithms on resource constrained IoT devices. Overall, this work represents a step toward future-proofing robotics communication ROS 2 systems based on DDS, against the quantum threats, as well as offering insights into the feasibility of post-quantum cryptography in resource constrained environments.
