Building an Efficient Side-Channel-Resilient Post-Quantum Root-of-Trust Design (Download)
The transition to post-quantum cryptography (PQC) is becoming an increasingly practical concern rather than a purely theoretical one. If large-scale quantum computers become viable, they could break the mathematical problems that current public-key systems such as RSA and elliptic curve cryptography rely on. As a result, many of today’s digital signature and key exchange mechanisms would no longer be secure.
This challenge is different from the situation with symmetric encryption like AES, where security can generally be preserved by increasing key sizes. In contrast, existing public-key schemes need to be replaced with entirely new quantum-resistant algorithms.
