Martijn Grooten - Elliptic Curve Cryptography for those who are afraid of maths

[@daryoushmehrtash7601]

The Best explanation! Thanks.

[@skdiamond]

Thanks. This is excellent. I had to watch it a few times but I get your explanation. In particular I appreciate your comments on what could go wrong and concerns with NSA.

[@mkmstillstackin]

I've watched a number of ecc explanation videos for math novices like myself. This is clearly one of the better ones and one I am much more able to understand. Great job. Thanks so much for sharing!

[@jamesinonati7608]

I like the speaker, and good explanation.

[@menesespaypa8765]

15:42 "there are good girls and bad girls" Of course

[@SmrutiDashiamironman]

Great explanation.

[@AnandKumar-zn3ox]

explained it so well ... thank you for this persentation

[@brendawilliams8062]

Nice. Thx

[@PamirTea]

Great talk, thank you.

[@andrdrcks8368]

I understand the spirit of the presentation; but, looks like some confusion between bits and bytes.

[@lapetiteanessesoap7559]

so clearly

[@prakashharionutube]

Superb Man.... Superb!!!

[@jeanFMoise]

Great decoder

[@frutiboy1]

"I don't think there is a secret formula for this large number that appears in the standard without explanation." is a pretty useless way of thinking about it.

[@emmanuelbyrd3389]

Can someone explain me or give more detail on what he says at 20:59 ??

[@ShokoDemon]

what don't you understand ? it's actually the basic way how random numbers are generated using an EC. thinking about vector * scala, where the vector is your random bytes array from /dev/random, and the point is an on the curve; even if your random bytes aren't random (assuming they aren't due to NSA shindig) the scala multiplication of your random bytes vector with the point will generate a better random point from the curve since multiplying a point on an EC curve makes it jump around in a seemingly /random/ manner. reversing this is /very/ costly for a CPU, or even a CPU cluster the size of several stadiums.

Nice book: Rational points on Elliptic curve, Springer 00:36

[@JohnSmith-bx4gf]

I watch this to treat insomnia

[@suhaibkhan4956]

in ECC , a point on curve is shared between two bodies. How is the message lets say "hello" is encrypted and decrypted using ECC?

[@Anonymous-ed4id]

still can't understand completely, but I think I got some idea... anyway, give up on understanding this... my math sucks.

[@longestchain9063]

mimblewimble!!!

[@tranquoc-binh5287]

You believe in what NSA provide? Are you nuts??? so if NSA knows the number d, then why are we using this security crypto? Thank you Martin for the great presentation. You have nailed the problem very well. I for one will not use ECC.

[@martijngrooten5294]

Thanks for the kind words. However, please note that I was not saying you shouldn't use ECC, just that you should avoid this particular implementation (and not just because of the NSA backdoor - it's bad for other reasons too).

[@bernardoramos9409]

Hi @@martijngrooten5294 , Could you inform a good and secure curve implementation? What about the secp256k1 used in Bitcoin?

[@wilsonbalderrama]

great speaker, explaining hard concepts in a very friendly way, kudos to him!

[@luizalmeida1209]

Thanks, awesome talk! :)

[@Prashantkrdey]

I believe that we should avoid the particular curve which is standard by NIST due to a possible backdoor. But then again how secure are the other curves? Moreover, since there has been questions even on SHA-256, then possibly the bitcoin is in risk.
