Post-Quantum Cryptography in Embedded Systems
Soundes Marzougui, Juliane Krämer · 2019
Quantum computers that can run Shor's algorithm are expected to become available in the next decade. These algorithms can be used to break conventional digital signature schemes (e.g. RSA or ECDSA), which are widely used in embedded systems today. This puts these systems at risk when they are used in safety-relevant long-term applications such as automotive systems or critical infrastructures. To mitigate this risk, classical digital signature schemes used must be replaced by schemes secure against quantum computer based attacks.
