What is Post-Quantum Cryptography?

Показать описание

Post-quantum cryptography (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms that are thought to be secure against an attack by a quantum computer.

Even if a standard solution to the post-quantum cryptography (PQC) problem is agreed upon, there is still the significant issue of rolling it out to millions upon millions of disparate devices. Life-critical systems like cars, phones, financial markets, national security and key infrastructure are vulnerable. What can we do?

Decrcrypting stored session data in the future, is perfect forward secrecy as solution to this "problem"? But besides that, this is a really interesting topic to prepare for in the race between computerpower en security.

Great introductory video to the topic!

Brilliant. I wonder if the q-bit will be able to restore a significate byte to its correct position in a 60000-byte file. I somehow doubt it. I think byte order manipulation is a powerful form of security which not talked about much.

Is it a good idea for thinking a phd in post -quantam crytography ??

Great explanation. Can I ask why is public-key cryptography vulnerable to quantum computers but symmetric cryptography is resistant (if it is in fact resistant) ?
