Just to clarify, it's definitely Dr. Alice's public key, right?

Wait, are we sure it's not Bob's private key? That seems odd.

I remember that in digital signatures, the sender's private key is used for signing, but for decryption, Bob should use the public key. So, it must be Dr. Alice's public key.

I’m a bit confused about whether Bob would use his own private key or Dr. Alice's public key. I need to double-check that.

This reminds me of a practice question where we had to identify keys used in encryption. I feel like the public key is definitely involved here.

I think Bob would use Dr. Alice's public key to decrypt the session key, but I'm not entirely sure.

This is a good test of our understanding of public-key cryptography. I think the key here is that Dr. Alice is encrypting the message, so Bob will need to use her public key to decrypt it and access the session key. The answer is B, Dr. Alice's public key.

I'm a bit confused by the wording of this question. Is Bob using Dr. Alice's public key to decrypt the session key, or is he using something else? I'll have to re-read the question a few times to make sure I understand it properly before answering.

Okay, let's see. Dr. Alice is encrypting the message and including her digital signature, so Bob will need to use her public key to verify the signature and decrypt the session key. I'm pretty sure the answer is B, Dr. Alice's public key.

Hmm, I'm a little unsure about this one. I know we covered digital signatures and session keys in class, but I'm not 100% confident I can apply that knowledge here. I'll have to think it through carefully.

This seems like a pretty straightforward question on public-key cryptography. I think I've got a good handle on this concept, so I'll give it a shot.

Option B is the way to go. Dr. Alice's public key is the one that should be used to verify her digital signature, and it's also the one used to encrypt the session key.

This is a tricky one, but I'm leaning towards C. Bob's public key would be the one used to encrypt the session key, so he can then decrypt it with his private key.
