Cisco Introduces Full-Stack Post-Quantum Cryptography Architecture
Summary
At Cisco Live 2026, Cisco unveiled the industry's first full-stack post-quantum cryptography (PQC) architecture using NIST-approved quantum-resistant algorithms, spanning from device boot integrity to data-in-transit protection. This represents the most significant cryptographic advancement in two decades, addressing the 'harvest now, decrypt later' threat posed by quantum computing.
Key Takeaways
Cisco's PQC architecture applies quantum-safe encryption to:
1) Device boot chain (C9000 switches use quantum-safe verified boot)
2) Network protocol layer (IPsec/MACsec with quantum-resistant key exchange)
Technical specs: Complies with NSA CNSA 2.0 timeline using NIST-standardized algorithm combinations.
