I wrote my final paper on this topic for my junior-year cryptography course for my Cybersecurity degree. i really wish i had these videos because she summed up a month's worth of research and writing into 7 minutes. this is a really awesome channel and ive already watch several other videos, all of them were just as excellent! keep up the good content
So psyched to have you back, Kelsey! I can't wait for all the awesome content to come. Congrats on starting this new project, and welcome back to UA-cam!!
Just heard they've decrypted 50 but RSA. Still far from 512 or 2048 but especially since bigger numbers are exponentially more difficult, but it's crazy how fast we're moving along
Great to see Dr. Houston-Edwards back! Would Chalk Talk consider an episode on AI/ML? Gradient descents, optimization, GAN, what happens when multiple AIs are trained on similar data sets but given different weights, etc. I read "Life 3.0" by Max Tegmark and the introduction is haunting. With ChatGPT consuming so much creative bandwidth, how do the Tegmark predictions fit into our current observations?
@ right, sorry for confusion. Let’s say 1 bit is the amount of data we can transfer per 1 read cycle. 1 qubit is able to transfer 0,1, or 0|1 at the same time. It’s not a rocket science to understand that quantum chip takes less time and energy to compute the result because it simply able to hold 2 bits at the same time. I guess, our encryption mechanisms with no regard to their sizes is breakable.
@@tilvalhallar9158 yes I already understand that a qubit is a super position of 2 bits thus much faster than classic central processing units, but I did hear that you would require millions of qubits to break something like AES-256, SHA-256 would take 8000 qubits or something like that, what I'm saying is since these two algorithms I've mentioned above is used in atleast 90 percent of the internet, to secure data, if a malicious actor gets hands on a computer in the future, when 100 qubits seems like nothing to us, or maybe even now, encrypted data can be easily brute forced into decryption, correct me if I'm wrong about anything I've mentioned here
Great content well explained. I think however that DH using ephemeral keys which is mandated by tlsv1.3 will not allow for future exploitation if the entire DH conversation is captured. Is this correct ?
No. Ephemeral keys means they're just changed very often. A quantum computer could break all of these keys very fast and decrypt the conversation. However if you've stored a huge amount of ephemeral keys and need to break all of then it would take a while but we can't rely on that for post quantum cryptography.
Since quantum computers are not good in precise floating point arithmetics lets use floating point functions for the new encryption algorithm, at least in parts
Brilliant video. Not sure why a brilliant mind like yours is denigrating the metric system. Using a preistoric imperial system based body part length doesn’t go very well with science. How many millions were lost for a satellite that crashed becouse someone used the imperial instead of metric.? Lives of people are at stake with that agency and misuring distances with length of human body part blow my mind😎
Always a joy listening to Dr. Houston-Edwards explain something complicated in a way that is approachable.
I hear commenting boosts visibility on UA-cam, and you deserve higher visibility. Great job!
Good to see Kelsey after all these years
Great to have you back Dr. Houston-Edwards!

What a terrific video, I’m so glad to have come across someone who explains complex things with such clarity

wow..what a clear explanation of everything in such a short video. All my doubts are cleared now,. Thankyou
You are amazing at explaining things. Glad to see you again.
Keep up the good work! Videos that clearly explains cryptography concepts are in short supply.

best series of videos that explain lattice based crypto for masses.
These are incredibly good videos. I have watched them all more than once. Thank you so much for creating these.
Fantastic explainer!

Your videos are awesome! Very clear and informative.
So well communicated. Excellent.
Your videos are on point. Thank you for publishing them!
This is an awesome video! I can't wait to see this channel speedrun to a million subscribers lol
Hahaha 😂 good comment. I hope that does happen!
Great video!!
Love your videos and channel. Thank you❤
Great video, thanks Kelsey; subscribed.
Very useful information. Is wire just like RCS?
Well-articulated! Thank you.
RSA or ECC encryption is breakable for qubit processor. Google said it can't decrypt RSA/ECC...
You're commenting this after seeing the willow quantum chip right, I'm concerned for our security, I feel like there will be no more of it

thank u for sharing
What's the story behind that square?.. ;)

arithmetics lets use floating point functions for the new encryption algorithm,
at least in parts
What about AES 256?
that is also vulnerable
@@neuekatze1 I don't think so. It will still offer 128 Bits of security which is still very high.
wow thats very interesting 😊
Thanks great vid
I guess we will have to get used to exchanging one-time pads in person.
Could you play Doom on a quantum computer?
quality content
0:34 “We’re not ‘anti-metric,’ we’re metrologically divergent.”
Maybe we are headed to another “Y2K” when all the encryption algorithms must be changed to a post quantum version.
Throwback to PBS Infinite Series!
NSA does, and has, for many years.
This isn't pbs math....🤔
IBM has built the quantum computer that can run Shor's.
RIP SIKE

2:36 Is it No one knows for Shor!? 🤣🤣🤣🤣

too much telepromptery and too much handwavingness
