Post-Quantum Cryptography: The Next Frontier

o prepare for quantum threats, enterprises are turning to post-quantum cryptography (PQC). PQC algorithms are designed to resist attacks from both classical and quantum computers. Key initiatives include:

• Hybrid encryption models: Combining classical and post-quantum algorithms to protect data during the transition period

• Quantum key distribution (QKD): Using the principles of quantum mechanics to securely exchange encryption keys

• Standards adoption: Organizations should monitor recommendations from bodies like NIST, which is actively standardizing PQC algorithms

Implementing PQC is not an overnight task. It requires inventorying systems, evaluating dependencies, testing new algorithms, and planning a phased rollout to maintain operational continuity.
