A second road to quantum safety: a Postquantum Preshared Key mixes an out-of-band secret into the IKE key schedule that never travels the wire, so even a classical handshake resists "harvest now, decrypt later," on gear not supporting ML-KEM.
We put Diffie-Hellman and ML-KEM side by side on size, latency, compute, and security, and land on the smartest move: a hybrid key exchange that runs both and combines their secrets, so an attacker would have to break both at once.
At Cisco Live 2026 Las Vegas, Cisco introduces a new branch and WAN architecture for the AI era, with AgenticOps, quantum-resilient security, simplified operations, and the expanded Cisco 8000 Series Secure Routers family.
In the ever-evolving threat landscape of cybersecurity, HNDL (Harvest Now, Decrypt Later) is emerging as a silent but serious threat. You don't need a crystal ball to defend against future risks - you need a roadmap. Learn how organizations can act
NIST developed new quantum-resistant cryptographic standards, but operationalizing these standards will require more work.
Using existing encryption and key management technologies, enterprises can realize quantum-safe encryption today without waiting for implementations.
GenAI & Quantum Computing forge a secure path across industry use cases. Where GenAI accelerates analysis, PQC safeguards data from future quantum threats. Together, they unlock a healthier future.
A metamorphosis continues to take shape with the rise of Post-Quantum Cryptography, Quantum Key Distribution, and the brave new world of Quantum Networking.
In just the past year, AI’s impact accelerated in startling ways. Many businesses are struggling to keep up, so Cisco is highlighting seven tech trends we expect to see in 2024 — and AI is integral across them all. Explore the novel ways in which you
