What is quantum cryptography: www.techtarget.com/searchsecu...
Try as we might, malicious actors can sometimes outsmart classical encryption methods, especially with accessible quantum computing. That’s where quantum cryptography comes into play -- it uses physics, not math, to secure messages. In theory, quantum key distribution is unhackable.

BB-84 is concise, simple, powerful, and truly a thing of beauty.

"Alice and Bob can then compare the splitter they used." How does that happen? If it's over the same channel that kind of defeats the purpose.

Same question.

The same way keys are shared classically, by completing a challenge and if you get the same answer, you're secure.

With respect to the OSI model then, does that mean that this is a layer one security system, where the only vulnerability that exists is if the polarizers are compromised or exploited?

Sounds like this may be the hidden sauce behind some crypto's.

What you are telling is not quantum cryptography, using light and fiber optic is normal cryptography not quantum cryptography. Quantum cryptography does not uses any back doors which is what allow it to secure data. Today computer uses back doors which allow multiple computers to be link. Back doors secure data but also make it vulnerable to hackers. Quantum cryptography secure data by not have back doors in the first place. This secure data from being hack but make it vulnerable to data being lost if something bad were to happen to main data.

You're not understanding this. It is against the laws of physics to have a back door into this system.

why are you all people using this same names in your examples...every video i've seen so far about cryptography it;s all Bob and Alice as the examples 😂😂😂

@EyeonTech Жыл бұрын

😂 That's a really good question! Alice and Bob are the standard placeholder names in various scientific fields so you don't have to say "Person A" and "Person B" over and over.

Just a slight credibility hit asserting that fiber optics must be used. It's just data. Copper can be used, RF transmission, LEOS... etc. Once it's encrypted, the media type doesn't matter

@nathancarnegie9912 Ай бұрын

Except for the fact that quantum cryptography uses Photons and last I checked RF and copper aren't photon transmitters
