Title:
Migrating Applications to Post-Quantum Cryptography: Beyond Algorithm Replacement

Authors: Alexandre Augusto Giron

Abstract:

Post-Quantum Cryptography (PQC) defines cryptographic algorithms designed to resist the advent of the quantum computer. Most public-key cryptosystems today are vulnerable to quantum attackers, so a global-scale transition to PQC is expected. As a result, several entities foment efforts in PQC standardization, research, development, creation of Work Groups (WGs), and issuing adoption recommendations. However, there is a long road to broad PQC adoption in practice. This position paper describes why migrating to PQC is necessary and gathers evidence that the ``hybrid mode’’ can help the migration process. Finally, it stresses that there are risks yet to be considered by the literature. Quantum-safe protocols are being evaluated, but more attention (and awareness) is needed for the software and protocols at the application layer. Lastly, this position paper gives further recommendations for a smother PQC migration.
