What are the key differences between quantum and classical cryptography?

What are the key differences between quantum and classical cryptography?

Classical cryptography relies on mathematical algorithms, while quantum cryptography uses quantum mechanics principles for security.

Can you explain how quantum cryptography ensures security?

Quantum cryptography uses quantum key distribution (QKD) to create secure keys, making eavesdropping detectable.

What are the advantages of using quantum cryptography?

Advantages include enhanced security, resistance to hacking, and the ability to detect eavesdropping.

Are there any limitations to quantum cryptography?

Yes, limitations include high costs, the need for specialized equipment, and current technological constraints.

How does classical cryptography handle security?

Classical cryptography uses algorithms like RSA and AES, relying on computational difficulty for security.
