Why Now Is the Perfect Time to Invest in Post-Quantum Cryptography 🔐

The post-quantum security ecosystem is one of the earliest places where you will see the earliest results from quantum technology. It’s now.

It’s not using quantum mechanics, because post-quantum cryptography uses classical mathematical methods to encrypt. But it’s needed to protect against the quantum computing threat.

Why does quantum security matters when large enough quantum computers don't yet exist to break modern encryption? As of July 2023, 5.2 billion people are using the internet.

We expect around 38.6 billion devices connected to the internet by 2025 and 50 billion by 2030.

One of the key takeaways here is that waiting is not an option. Large-scale quantum computers are already on the horizon and once they become mainstream, they could use Shor's algorithm to break RSA and Elliptic Curve Cryptography (ECC)—two forms of encryption we rely on today. These algorithms underpin our entire digital infrastructure, from sending emails to processing transactions.

But maybe you say, that’s so far away - 2030s. It doesn’t matter!

Actually, it took 10 years to replace ECC from RSA last time for compliance. That’s why the National Institute of Standards and Technology (NIST) began standardizing Post-Quantum Cryptography (PQC) back in 2016. The goal of the project is to develop public-key cryptographic algorithms that can protect sensitive government information, even after the advent of quantum computers. They knew it was coming, and it’d take time to develop the standards, not to mention transition our entire digital infrastructure to them.

Regulatory bodies and governments are setting the pace, even helping to fund the quantum computing technologies through academic grants and industry investments. So, replacing this foundation is urgent and lucrative.
