the best explanation of lattice in youtube 🔥

nice work! thanks : )

What an amazing explanation!!! I believe you should teach Mathematicians how to teach!

noooooooooooo why are you gone again?!? why did I not find the channel earlier? whhhhhy edit: oh, I am so sad

This video is so cool 😎 thx

Well-articulated! Thank you.

Well-articulated! Thank you.

Well-articulated! Thank you.

This only works with very short messages. It’s not generalizable to, say, a one page letter. It’s equivalent to sending a blurry image that the recipient can sharpen but so could a mitm. I’m not so sure this is as unsolvable as you think, and if it were, both Alice and Bob would need a way to share the actual errors securely in the future.

such a beautifully well done video. Thank you for taking an intimidating concept and making it accessible.

this was amazing!

very pleasant to watch.

What about AES 256?

5:15 but couldnt malkob(bobs bully) just calculate that 30x+67y+53z+24w=19(mod 89) is 0 and then check if it is equal to 0

Very clear explanation! Thank you!

Thank you so much. It's so simple and understandable

It is unclear how F gets its private key at 6'16''. It is also unclear why the rachet can go up the tree as well as down the tree.

I love you ❤

How are things supposed to be bruteforce proof if the decryption is supposed to offline

Always a joy listening to Dr. Houston-Edwards explain something complicated in a way that is approachable.

How do you create this kind of representation and animations of point lattices? I am writting a university project about post quantum cryptography, and I would like to introduce pictures and visualizations about lattices. Thanks :)

this short video series was very informative on learning the core of PQC algorithms. Especially since now apple after signal implemented a PQC algorithm.

c'est si clair et si bien expliqué. merci beaucoup !

First sponsorship I ever saw with less than 5k subscribers.

<3

Anyone know what happened to the channel? or where to find similar ed videos?

This was so helpful, thanks for taking the time to make this very understandable.

What happened to this channel? The videos were quite good and then they just stopped.

Love your videos and channel. Thank you❤

This video saved me a lot of time and confusion. Thank you so much for your great videos ♡♡♡

Great presentation! The basic concept of lattice-based cryptography looks simple which I think is good for analyzing it in terms of security.

This channel is wildly underrated!

When Bob adds 44 to encode a "1", how do we know that it results in a point that is far from all the lattice points? Is there an argument to show this?

Awesome video! Going with the intuition first without going into too much details. I wish to see more in the future.

The best 👍

wow..what a clear explanation of everything in such a short video. All my doubts are cleared now,. Thankyou

Regular people: just another thing to look at. Mathematician: why can't I make a mathematical model of this

Thanks! Would those noisy linear constraints be solved with linear regression?

Very good video, glad this is the first video that showed up when I searched for this topic

Could someone please share KYPER technique that perform the encryption and decryption?

Thank you so much! Video is intuitive enough to cover working principles of Post Quantum Cryptography. :)

Your videos are awesome! Very clear and informative.

😍 i'm in love. Who said maths arent Beautyful ?

So this has a major concern in my mind, while the math for this might be challenging when you step things up into more variables, there is also a deterministic quality to these problems when there is a large sample population of messages with the same secret key and mod. You would have to find a way to modify the secret key and mod and also communicate those changes over the network. This is ultimately the challenge, especially considering the passive listening that is happening over networks by state actors that have access to these large quantum computers. These problems will basically create a guaranteed back door for whoever controls the network and only really protect against people who are not the government.

amazing video, amazing series, and amazing effort. Thank you so much for the illustration, really helped so much.
