Quantum Key Distribution (QKD): Why Countries Differ on Its Future
Quantum Key Distribution (QKD) - a method of securing communications using quantum physics - has become a flashpoint of debate worldwide. Recent news (like Google’s announcement favoring post-quantum algorithms over QKD) highlights how divided opinions are. Some nations are investing heavily in QKD networks as the next frontier of secure communications, while others remain skeptical and prioritize post-quantum cryptography (PQC). United States and Allies: Emphasizing…

Why We Need a Quantum Security ISAC
Quantum computing promises revolutionary capabilities, but it also poses unprecedented threats to cybersecurity. Experts warn of a looming “Quantum Apocalypse” scenario - the day when a sufficiently advanced quantum computer can crack encryption like RSA or ECC, exposing sensitive data that was once considered secure. And of course, there's the already present "harvest now, decrypt later." The potential impact of cryptography-breaking quantum computers is global…

Securing Quantum Computers – Threat at the Quantum-Classical Interface
A global race is on to build cryptographically relevant quantum computers (CRQCs) - machines powerful enough to break current encryption. Governments and industry are pouring billions into quantum R&D, and intelligence analysts scrutinize whether a geopolitical rival might secretly be ahead. Yet amid this focus on who builds a quantum codebreaker first, an alternative threat vector is often overlooked: an adversary might not need to…

Q-Day Isn’t an Outage – It’s a Confidence Crisis
Cybersecurity lore often paints Q-Day (the moment a quantum computer cracks RSA/ECC encryption) as an instant "Quantum Apocalypse" where every system gets hacked immediately. Planes falling from the sky, banks drained in seconds, an overnight digital Armageddon - if that nightmare doesn’t happen, some assume Q-Day wasn’t so bad after all. But this view misses a crucial point. The real catastrophe of Q-Day isn’t that…

Post-Quantum Negligence: Legal Risks of Failing to Prepare for the Quantum Threat
Quantum computing is no longer a far-off hypothesis - it’s a rapidly emerging reality that could render today’s encryption obsolete. For CISOs and their boards, this means a new kind of cybersecurity crisis is on the horizon. Sensitive data that is safely encrypted now may be sitting like a ticking time bomb, waiting to be cracked by tomorrow’s quantum machines. The message is clear: security…

Sovereignty in the Post-Quantum Cryptography (PQC) Era
Post-Quantum Cryptography (PQC) is entering the standards stage, with the U.S. National Institute of Standards and Technology (NIST) recently selecting the first quantum-resistant algorithms. However, the future of PQC will not be as straightforward as simply adopting NIST’s choices globally. A strong push for digital sovereignty is emerging around the world, driven by eroding trust in foreign (particularly U.S.) technology. Nations are seeking greater control…

Trust Now, Forge Later (TNFL) – The Overlooked Quantum Threat
What is "Trust Now, Forge Later" (TNFL)? Most discussions about quantum computing threats focus on “Harvest Now, Decrypt Later” (HNDL) - the idea that adversaries can collect encrypted data today and store it, hoping a future quantum computer will break the encryption and expose sensitive information. This risk is very real, especially for data that needs to remain confidential for decades (think government secrets, health…
