____________cryptography uses one key to encrypt a message and a different key to decrypt it.

Show Suggested Answer Hide Answer
Suggested Answer: B

Asymmetric

https://en.wikipedia.org/wiki/Public-key_cryptography

Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys: public keys, which may be disseminated widely, and private keys, which are known only to the owner. The generation of such keys depends on cryptographic algorithms based on mathematical problems to produce one-way functions. Effective security only requires keeping the private key private; the public key can be openly distributed without compromising security.

I'm going with B) Asymmetric. It sounds like the most logical choice, and I'm not about to fall for any crypto-themed puns or jokes on this exam.

Asymmetric cryptography, for sure. It's the one that uses public and private keys. I bet the person who wrote this question is a big fan of RSA.

Wait, is this a trick question? What if the answer is 'all of the above'? Cryptography can be so confusing sometimes.

Hmm, I'm not sure. Isn't symmetric cryptography the one that uses the same key for both encryption and decryption? I'll have to think about this one a bit more.

That makes sense. Asymmetric cryptography provides an extra layer of security compared to symmetric cryptography.

Duh, it's obviously asymmetric. I learned that in my crypto class last semester. This exam is a piece of cake!

I agree with Galen, symmetric cryptography is more efficient for communication between two parties.

I think it's D) Symmetric because it uses the same key for encryption and decryption.

I think it has to be asymmetric cryptography. That's the one where you use different keys for encryption and decryption, right?
