Post-Quantum Cryptography: Securing Our Digital Life

Much has happened since last years video about the Chinese paper on cracking RSA2048 using Shor's algorithm on powerful Quantum Computers. In this video I pickup where I left off and talk about what has happended in a year.

I feel like this is the next y2k in terms of impending crisis, when things get closer there will be a large conversion to more complex encryption methods for our data en masse. Just not sure how far in the future this will be.

[savagepro]

Won't the insurgence of AI and the insurgence of Quantum Computing collide? Or even worse, AI+Quantum Computing against the rest?

[alexxx]

Last time I checked, quantum computers were too noisy for any practical application. Anything improved?

[comosaycomosah]

I know i think about this too it will be a mess for everything potentially lol

[savagepro]

I say we just go back to Smoke Signals! Take that, AI.

"reproducibility" is what you should concern yourself first with anything coming from china.

Someone watching this video might construe the statement ‘Kyber’ is a replacement for AES’ to imply that Kyber would be a quantum-safe replacement for the very widely-used AES encryption. However, this implication is inaccurate. AES is a symmetric encryption algorithm and as such is inherently quantum safe (at least with reasonable key sizes). In other words, there is no need to “replace” AES with Kyber if the concern at hand is quantum safety. (Note that the paper shown in the video notes that Kyber is ‘equivalent’ to AES, rather than a potential replacement for it.) Quantum computing mainly poses a threat for public-key based encryption but not so much for symmetric encryption algorithms. Unfortunately, this point is not widely known or understood by the lay public.

[LMB]

No, it won't.

Or more exactly, quantum computing won't come in this generation, nor the next one.

Probably they can crack code but initially the will cost a lot and also will not able to process all data of the world, so this would hopefully gave enough time to create countermeasures

Sir can you please tell me what is that github page name?
