In today’s fast-paced technological environment, cybersecurity is facing critical challenges, especially with the rise of quantum computing. This advancement threatens traditional cryptographic systems, such as RSA, which could soon be vulnerable to powerful quantum-based attacks. To mitigate this risk, the field of Post-Quantum Cryptography (PQC) aims to develop algorithms resilient to quantum capabilities. Despite progress in PQC, incorporating these algorithms into existing systems requires careful adaptation to maintain performance and usability. One key area where PQC solutions are essential is in embedded devices' secure and measured boot processes. These processes ensure that only trusted software loads at startup, protecting unauthorised access and potential threats.
