Post-quantum cryptography
- You may think you need a degree in math to understand post-quantum cryptography or PQC, but that's not the case. PQC is the term used for cryptographic algorithms that are designed to be secure against attacks by quantum computers. The algorithms in use before the introduction of quantum computers, such as RSA and ECC, can take a lifetime to break. Now, I've seen projections like a million or a billion years to break, but quantum computers with Shor's algorithm cut that timeframe down to minutes or hours at most. Here's how it works. Imagine a game with thousands of keys and thousands of locks, where only one key fits one lock. Traditionally, finding the right key for a lock through a process of elimination could take an incredibly long time. That's what encryption is like today. Now envision being able to operate at a rate thousands of times faster. Thanks to quantum computing, you may be able to find the lock-to-key combination a lot faster. Suddenly, data we've encrypted and…
