All things decrypted
In this edition, we dive into the growing importance of post-quantum cryptography (PQC) and hybrid encryption as a key approach to protect sensitive data from the future threats of quantum computing.
We’re also proud to announce that Cosmian covercrypt has received ETSI standardization, a major milestone in safeguarding data in a world where security is more critical than ever.
📢 You’ll also find a curated selection of recent articles on PQC, along with a comparative analysis of hybrid vs. non-hybrid strategies in Europe and the US.

🛡️ Why Act Now? The Global Push Toward Post-Quantum Cryptography
The rise of quantum computing fundamentally challenges the security of current encryption systems. In response, global cybersecurity authorities are mobilizing. The US, UK, and Europe all acknowledge the urgent need to transition to quantum-resistant cryptography.
The US leads the race. The National Institute of Standards and Technology (NIST) launched its post-quantum algorithm selection process back in 2016. Here are the key dates:
➡️ 2016: Launch of the post-quantum algorithm selection process
➡️ 2022: Announcement of the first 4 selected algorithms (Kyber, Dilithium, etc.)
➡️ 2024: Official release of the first post-quantum standards
➡️ 2025: Recommended start of deployment in critical infrastructure
➡️ 2027+: Goal of widespread adoption across sensitive sectors
📌 NIST recommends organizations start planning now using a crypto-agile approach.
The UK’s National Cyber Security Centre (NCSC) is also encouraging organizations to prepare. In a recent publication, the NCSC offers concrete guidance and suggested migration timelines, emphasizing the need for agility and strategic anticipation.
📌 Planning your post-quantum migration – A clear action guide from the NCSC
In a joint statement, France’s ANSSI and Germany’s BSI urge immediate action toward PQC transition. However, unlike the US and UK, no specific timeline has been announced yet. While the strategic intent is clear, implementation deadlines are still pending.

🔍 Explaining the Basics: Hybrid vs. Non-Hybrid Approaches
Europe, supported by ANSSI and ETSI, champions hybrid encryption, which combines classical and post-quantum algorithms. In contrast, the US—via NIST—favors a direct switch to purely post-quantum algorithms.
💡 Key takeaways
✅ Double-layer protection: If one algorithm fails, the other ensures security
✅ Flexible migration: Organizations can transition progressively

✅ Two strategic paths: Europe opts for hybrid pragmatism, the US for full replacement
👉 Choosing hybrid doesn’t exclude the non-hybrid path later—but the reverse isn’t true.
Indeed, the NIST has chosen a non-hybrid path—favoring post-quantum-only algorithms (PQC), such as Kyber or Dilithium, without combining them with legacy algorithms.
➡️ Goal: Replace existing systems with rigorously vetted, standalone PQC standards
✅ Benefits: Simpler long-term architecture, optimized performance
❌ Risks: If the selected PQC algorithm is broken, there’s no fallback layer.
