The Cost of Quantum Safety Implementing Post-Quantum Cryptography

Adopting Post-Quantum Cryptography is not without its challenges and costs. Transitioning to PQC from classical cryptographic methods requires significant investment in both time and resources. This encompasses updating hardware, software, and digital infrastructure to support new algorithms, as well as retraining staff to manage and maintain these updated systems. Furthermore, the preliminary nature of some PQC methods may also introduce new vulnerabilities or decrease system performance. Despite these challenges, the cost of implementing PQC pales in comparison to the potential risks of quantum-level cyber attacks.
