Finite Fields in Cryptography: Why and How

Learn about a practical motivation for using finite fields in cryptography, the boring definition, a slightly more fun example with monsters, and how to create fields out of some sets of integers.

Your explanation of finite fields was INCREDIBLY useful! Thank you so much for taking the time to create this content and share it with the community.

Man, that's the super coolest explannation of groups I've ever seen. The monsters group is hilarious! Thank you! I'll subscribe and will wait another 2 years for the next video.

Having no downvotes tells us a lot about the quality of your videos...

[xjuaan]

All the explanations in this video are just perfect. Thanks for this!

[teewenhui]

i love the 2nd half with the island example, its so cute and intuitive

[serophots]

Incredibly helpful approach to the problem

[ezohn]

thanks for sharing. For a non-computer scientist like me, a very clear explanation why FFs are used in cryptography!

[FitVibhav]

Actually, I was Looking Video for my frnd
But, when I saw whole Video really its awesome☺☺

[markandmelbamford]

Agree with other reviewers- best explanation of fields rings groups. I’ll look for other videos too

[azagogh]

YES! I love the example of the creatures, and how elements can be anything, .

[qianyingliao]

Thank you for explaining the finite field in the most intuitive way!

I'm only 3 minutes in and I can tell this video will be very helpful. Thanks for your effort and keep going 🙌

[ByteNishi]

Nice, Thank you! Today only I got the channel in my recommendations and I am already liking it.

[sachuabraham]

Really nice explanation, Hoping to see more videos

[NormalHuman]

really good explanation, thank you for spending your time to make this

[SaidVSMath]

Great video, I'm interested in learning about cryptography and this opened my eyes! Thanks!

[codegeek]

Definitely interested in the prime power fields. It's impossible to find any online explainer for them that's "accessible" to mortals — people with less than graduate-level math background — I say this as a "mortal" myself... 😭

Subscribed! - really nice presentation, especially liked the graphs showing perfect secrecy.

your vids are really helpful. I hope u will release more vids soon.

Nitpick: additive and multiplicative identities need not be distinct, as shown by the existence of the trivial field {0}. Exercise for the reader: prove that the two identities are indeed distinct for all other (nontrivial) fields.
