Yes, that's another reason why RSA is vulnerable to quantum computing attacks.

But isn't it also because quantum computers can solve the discrete logarithm problem?

I agree with Rashad, quantum computers can break RSA encryption by factoring large integers quickly.

Quantum computing is like a superpower that can break the encryption we've been relying on for years. It's like the crypto version of the Hulk – you don't want to be on the wrong side of that.

I'm surprised the answer isn't B. I thought quantum computers could solve the discrete logarithm problem, which is the foundation of RSA. But I guess factoring large integers is even worse.

Wow, option D is really scary. Imagine your bank account getting hacked because of quantum computers. I need to start learning quantum mechanics, just in case.

I agree with Kristin. Quantum computing is a game-changer, and RSA is in big trouble. I can't wait to see how they'll adapt to this new reality.

Option D is the correct answer. Quantum computers can break the RSA encryption by factoring large integers in polynomial time, which is a huge threat to the security of RSA.
