WHITE PAPER

Quantum-Ready Security: A Phased Path Toward Key Distribution Resilience

The race to secure data against quantum computing is on — and waiting until quantum attacks materialize means it's already too late. As quantum capabilities advance, the risk of Harvest Now, Decrypt Later (HNDL) attacks grows, putting critical data in motion at immediate risk.

In this new SANS white paper, produced in partnership with Quantum Xchange, leading cybersecurity researchers outline a clear, phased strategy for achieving quantum-ready security.

You'll gain expert insights into how to strengthen existing encryption systems today while preparing for post-quantum cryptography (PQC) tomorrow.

Discover how out-of-band key delivery, ephemeral key management, and crypto-agility combine to deliver stronger data protection and measurable resilience—without replacing your existing infrastructure.

Read the paper to learn how to:

  • Understand the quantum threat and why acting now is essential

  • Address encryption weaknesses while preparing for PQC adoption

  • Use out-of-band key delivery and Ephemeral Keyless Forward Secrecy (EKFS) to protect against key compromise

  • Build a phased, non-disruptive roadmap to quantum-safe distribution

"The prospect of harvest-now, decrypt-later attacks is already a concern, making the post-quantum cryptography transition an urgent priority."
