RE: Quantum Computing
« on: September 16, 2015, 06:20:42 pm »
Hello tech pro's, quick question:
Can quantum computing technology be a future threat to cryptography technology?  Will QC be able to crack cryptographic messages?  Thanks for your time!

Possibly, but if this happens its still quite a ways off.

If they can change the "E" in Berenstein Bears to an "A" and make it "BerenstAin" by traveling back in time ... anything is possible!

All crypto tech relies on finding things that are easy for a machine to do in one direction, but hard to do in another (easy to encrypt, hard to decrypt). Machines that run code in sequence find it very hard to crack RSA, but machines that approach problems differently (quantum computers) have no problem with it. So RSA, current hashing techniques, won't be useful in a world with useful quantum computers.

At the same time, new crypto tech will emerge such as quantum cryptography https://en.wikipedia.org/wiki/Quantum_key_distribution

Just like the enigma (https://en.wikipedia.org/wiki/Enigma_machine) was practically unbreakable before computers (https://en.wikipedia.org/wiki/Bombe), new tech will both make current crypto obsolete and present the platform for the next gen of crypto
