“But Mike… there is no FUD in Post-Quantum Cryptography.”
I’m glad you brought that up, because that’s exactly what this post is about.
When people hear the term Post-Quantum Cryptography (PQC), the conversation often goes in one of two directions. Some claim that quantum computers are still decades away and that there’s nothing to worry about. Others make it sound as if RSA will stop working sometime next Tuesday, neither view tells the whole story. The reality is far more interesting, and far more nuanced than many have you believe, Post-Quantum Cryptography isn’t about fear, uncertainty, or doubt. It’s about understanding the actual risks, separating scientific facts from headlines, and making informed architectural decisions based on evidence rather than speculation.
So, let’s take the FUD out of the discussion. In this blog, we’ll look at what current research actually tells us about quantum computers, why symmetric encryption such as AES is in a very different position than RSA and ECC, who is realistically capable of building a cryptographically relevant quantum computer, and why organizations should begin preparing today, even though the first machine capable of breaking modern public key cryptography is unlikely to appear in your local datacenter anytime soon. Because the real challenge isn’t that quantum computers are coming. The real challenge is making sure your organization is ready when they do.
