Attack Profiles for PQC, QKD, and QSC

As quantum computing continues to progress, it’s prompting new conversations around cybersecurity and a fresh look at today’s cryptographic methods. Even the most advanced data protection is under scrutiny. To stay ahead of threats posed by AI and quantum computation, it’s important to understand how Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and Quantum Secure Communication (QSC) each contribute to security, and where they could fall short in real-world use. Just like a fruit salad mixes different fruits to balance taste and nutrition, a security architecture blends PQC, QKD, and QSC to cover a wider range of threats.
