How quantum physics can make encryption stronger | Vikram Sharma

Показать описание

As quantum computing matures, it's going to bring unimaginable increases in computational power along with it -- and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.

I'm more impressed that he's on a first name basis with James Bond.

Nice story to understand the three key elements of encryption: key, exchange and algorithm. Vikram Sharma has solved the first two using quantum computing, which was the apparent enemy to encryption itself. Hope he is able to solve the third element i.e. algorithm, using quantum effects. All the best!

Great talk, but months old, wish you all would have put the original record date in the description.

Isn't RSA only theoretically broken by Shor's algorithm on quantum computers? The way he described it in the talk made it sound like classical computers can break it.

What about brute force attack with quantum computing?

So I know a bit about quantum physics however I don't see how it could help encryption... I also know a lot about programming/ hacking/ and things of that nature. Tell me your thoughts (haven't watched the entire video yet)

this popped up in my recommended while doing my ap physics homework, so I decided to listen while doing it

Wow..great...finally I understood and I got an overview 😊

The casino example was a good one! It's well explored. Nice one!

How about using the white noise on a reverse biased diode connected to a schmitt trigger for a truly random generator? It only costs pennys.

I liked his quantum card, but he barely explained the best parts of encryption.

The fiber optic laser password fingerprint can be intercepted and copied as soon as the clocks from the two computers can be modified to lie about the send and recieve times. Therefore no interruption will be visible. If the message is sent and recieved by false clock times

1:56 first you make me pack my stuff and now I need to put everything back?

Predicting the future is usually wrong as we can't think about what we don't know will exist in the future.
And will the future show that quantum effects aren't "truly random"?

If there's a security breach in today's system using encryption - it's not because someone had a powerful enough computer to brute force it or algorithms didn't have enough randomness. It's mostly because of some humane mistake or an exploit no encryption could've prevented. Seems like this talk had intentional misleading and fearmongering in order to promote some security companies and their products.

You know how to achieve "true" randomness in computing? Calculate input values from user's mouse movement and tell him/her to randomly wiggle it. VeraCrypt does this. That simple. No much need for +10k dollar "randomness chips" this guy is probably selling from his company.

But of course there's "quantum" buzzword so we have iamverysmarts applauding "REAL TED TALK" when there's actually very little substance in the talk itself.
