Post-Quantum Cryptography (PQC) in Embedded Linux Systems - Ajith P Venugopal, Bosch Global Software Technologies Private Limited

The presentation explores the growing threat of quantum computers to traditional cryptographic algorithms used in embedded Linux systems. It begins with an overview of current security algorithms (RSA, ECC, AES) and their vulnerabilities to quantum attacks.

The session explains quantum computing principles—including qubits, superposition, and entanglement—and how algorithms like Shor’s and Grover’s can break or weaken existing encryption methods. The presentation highlights recent advancements in quantum computing, their impact on cybersecurity, and why embedded Linux systems, often lacking real-time updates, are especially vulnerable.

To give a suitable use case, the presentation takes Crystals-Dilithium, a lattice-based PQC algorithm selected by NIST, ensuring quantum-resistant digital signature for embedded Linux devices (Ex: NXP i.MX platforms). The session concludes with Q&A to discuss future-proofing security with PQC and also mention about the initiatives such as Post-Quantum Cryptography Alliance (PQCA) from Linux Foundation.
