AES GCM (Advanced Encryption Standard in Galois Counter Mode) - Computerphile

Your browser is using this system right now! (at time of typing!) - Dr Mike Pound explains this ubiquitous system!

This video was filmed and edited by Sean Riley.

Prof. Pound teaches in such an elegant manner, as easy as possible for such a difficult subject, with nothing but paper and pens... Please, guys, give him a wide whiteboard!

A 18 minute crypto video with Dr Pound! Feels like christmas 😁

Can you please do a video on the xz backdoor vulnerability that was recently discovered?

[liquidmobius]

It's like you just have an empty office where you keep these guys on tap for us 😂

Something to note: In a Galois field, multiplication is the polynomial operation described, and addition/subtraction is XOR!
This is what motivates using + and x (XOR distributes over Galois multiplication)

I can't wait for his take on the xz exploit. So intricate

I come across GCM all the time when setting up IPsec VPN tunnels, now it makes sense why you don’t have a separate hashing algorithm!!

17:22 "but you've got to consider you don't want to truncate it too much because if you only took the first bit of a tag then you've got a 50/50 chance"

The thing about Mike Poind is that he cracks jokes in the serious flow of the conversation.

We never got to the modes like GCM in my crypto class when i took it a few years ago. So I'm happy to actually learn it now lmao

[Smoth]

Never would have clicked on this but I'm studying for my CompTIA security+ exam and this was genuinely so helpful and well explained haha, thank you!

[paulopacitti]

I watched many videos from Dr. Pound while doing the Cryptography class at the State University of Campinas. I wish this video was released sooner, it would be easier to study for the exams 😂

Hey yoo, such a coincidence, I was researching about the AES for my Go app just the other day. This is very helpful, thank <3

[cedric-johnson]

Can we set a gofundme page for dr Pound, he is in need of more paper for sure. Btw always love Dr. Pounds mini lectures, keep going strong 💪

[phpn]

Few deserve the title of Doctor, as evidently as Mr Pound does

[draugno]

this was very informative and interesting and made me miss my uni days

[velho]

Just a request, could Dr. Pound cover the latest XZ schemes. It would be awesome! Great video btw

[t.g.]

Can you do video on chacha20-poly1305? I've heard it's faster than aes without hardware acceleration?

[pauloavelar]

Seeing how many cycles are basically "wasted" due to our need to protect ourselves from bad actors is kinda crazy. I guess it's not that different from military investments, high fences or whatever, but because it is performed for every single message as opposed to an investment early on that pays off, it feels like having to carry a gun and put on armor plates to go check the mail.

POWND, Da POUND Dawg! It's the POUND Town

[keyurjoshi]

Why is a simple HMAC not sufficient to check that the decrypted plaintext wasn't tampered with?
