I thought it was known-plaintext attack at first.

I feel like I’ve seen differential cryptanalysis mentioned in this context before, but it doesn’t seem to fit the question.

I’m a bit confused; I thought known-plaintext attacks were similar, but they involve the attacker having some plaintext and its ciphertext, right?

Ugh, I'm drawing a blank on the specific name for this type of attack. I know it has to do with the attacker being able to choose the plaintexts, but I can't recall the exact term. Guess I'll have to make an educated guess here.

Ah, I remember this one! It's the chosen plaintext attack, where the attacker can select the plaintexts they want encrypted and analyze the resulting ciphertexts. Definitely option A.

Hmm, I'm a bit unsure on this one. Is it a known-plaintext attack, where the attacker has access to some plaintext-ciphertext pairs? Or is it something else? I'll have to think this through carefully.

I'm pretty sure this is a chosen plaintext attack, where the attacker gets to choose the plaintexts and see the corresponding ciphertexts. That's one of the key cryptanalysis techniques we covered in class.

B, Differential cryptanalysis, seems legit. Although I'm just guessing since crypto is not my strong suit.

I'm going with C. Known-plaintext attack makes the most sense here, since the attacker has access to both the plaintexts and ciphertexts.

Definitely option A. The attacker selects the plaintexts and gets the corresponding ciphertexts - that's a textbook chosen plaintext attack!
