The scenario sounds like science fiction. Adversaries are right now harvesting and storing encrypted data they cannot yet read—banking transactions, state secrets, medical records, intellectual property—betting that quantum computers will eventually break today's encryption. They're playing the long game, and they're winning because most of us are still pretending this isn't happening.
This isn't theoretical anymore. This is a live threat unfolding in real time, and if you're responsible for security infrastructure, you need to act today, not when quantum computers arrive.
The Harvest Now, Decrypt Later Reality
Let me be direct: if your organization handles sensitive data with a lifespan beyond five to ten years, you're already exposed. Here's why.
The mathematics underpinning RSA and elliptic curve cryptography—the algorithms protecting everything from your SWIFT transfers to your healthcare records—remain secure against classical computers. A 2048-bit RSA key would take conventional supercomputers thousands of years to crack. That's not a weakness; it's by design.
