Migrating Applications to Post-Quantum Cryptography: Beyond Algorithm Replacement

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.
