Preparing for a Future with Post-Quantum Cryptography

As we step into 2026, the buzz around post-quantum cryptography (PQC) is becoming more urgent. Once an abstract topic, it’s now a pressing issue, with experts urging updates to PQC strategies. Simply put, staying current with your cryptographic tools is essential.

The good news? Pioneering PQC steps are already in play. These include PQC-compatible code signing for firmware and software, hybrid public key infrastructure (PKI) certificates, and alternative PQC algorithms for critical applications.

Understanding the Quantum Challenge

The crux of the problem is quantum computers. They’re expected to eventually crack the cryptographic keys we currently rely on. The big question is when this will happen, and when these quantum powers might fall into the wrong hands.

Gartner predicts that by 2029, quantum advancements could render today’s cryptography useless, potentially becoming breakable by 2034. Plus, the “harvest-now, decrypt-later” strategies may already be in play.

While timelines vary, the risk of cryptographically relevant quantum computers emerging soon is something few can ignore. Blair Canavan of Thales Group underlines, “The time to act is now.”

Regulatory support further underscores this urgency. The National Institute of Standards and Technology (NIST) has approved several PQC algorithms, emphasizing readiness.

Steps to Ready Your Organization for PQC

Thales suggests three crucial steps for embracing a post-quantum world:

• Evaluate Your Environment: Cryptography is woven throughout today’s businesses. You must map systems—think certificates, encryption keys, algorithms, and protocols. It’s like finding needles in a haystack, but crucial for prioritizing your approach.
• Analyze Available Solutions: Seek solutions that decouple cryptography from applications, enabling flexibility. It’s all about implementing the right algorithm based on sensitivity.
• Adopt a Hybrid Strategy: According to NIST, a policy-driven approach eases transitions between algorithms, allowing traditional and PQC systems to coexist for smoother transitions.

Navigating this shift is complex. Many organizations will seek expert help. Thales Group and its partners are poised to guide businesses through this significant transformation.

In this race against time, quick action is essential to secure future cryptography. For more insights on PQC strategies, tap into Thales’ resources.
