Introduction: The Quantum Threat to Federated Learning
Okay, so, quantum computers, right? They're getting real good, real fast. But that means trouble for stuff we thought was safe, like federated learning. Is your data really protected?
- Federated learning shares model updates, but they're often encrypted with, like, RSA.
- Quantum computers can crack RSA easy, thanks to Shor's algorithm.
- This means someone could grab your data now and decrypt it later when they got a quantum computer. It's called "harvest now, decrypt later."
Scary, huh? Let's see what we can do about it! Enhancing Quantum Security over Federated Learning via Post-Quantum Cryptography - this paper talks about some algorithms that might help.
