Post-Quantum Cryptography Migration Challenges for Embedded Devices

This white paper discusses the migration challenges associated with implementing post-quantum cryptography (PQC) on embedded devices. It outlines the unique limitations faced by these resource-constrained systems, including computational power, memory, and energy consumption. The document details the upcoming PQC standards and the complexities involved in integrating quantum-safe algorithms while managing performance trade-offs. Key considerations include the necessity for efficient implementations that minimize computational overhead and maintain security against potential side-channel and fault attacks. The paper emphasizes the importance of a multidisciplinary approach that encompasses cryptographic research, hardware design, software development, and system integration to ensure the resilience of embedded systems against the threats posed by quantum computing. It also highlights the proactive measures needed for successful migration to PQC, which is crucial as quantum computing technology continues to advance.
