It's definitely the Meet-in-the-middle attack!

I feel like I’ve seen something about the Meet-in-the-middle attack being less secure than using a single key, but I can't recall the details clearly.

I’m a bit confused; I thought the Man-in-the-middle attack was more about intercepting communications, not specifically about DES.

I remember practicing a question about attacks on DES, and I think the Meet-in-the-middle was mentioned there too.

I think the answer might be the Meet-in-the-middle attack, but I'm not entirely sure. It sounds familiar from my notes.

I'm uncertain... could it be that all listed IPs are just restricted for access, or is it about blocking them entirely?
