Quantum Cryptography: Rain on the Parade

November 11, 2019

I know (not too well, which may be a good thing) who is trying to cash in the quantum gold rush. The angle for this entrepreneur is that quantum computing will allow government entities to break encryption.

The hitch in the git along is that there are bad actors who are involved in quantum computing. There are good actors who are creating quantum-safe cryptography with quantum computers.

Confused? Don’t be. People who need to encrypt gravitate to the high horsepower computers. The people who want to break encryption do what’s necessary to get access to quantum computers. The method used by Saudi Arabia to obtain specific social media data worked like a champ.

That brings me to “Komodo to Lead Blockchain Revolution with Quantum-Safe Cryptography.” The write up says:

As a blockchain platform, Stadelmann said that Komodo is trying to solve the problem and has implemented quantum-safe cryptographic solutions for the past couple of years which will not be able to crack cryptographic signatures. Using an IBM-built technology, known as Dilithium, into its blockchain platform, he said the new digital signature algorithm will create a key which cannot be cracked by a quantum computer.

Sounds good. Just another cat and mouse game. The people working to cash in on this scare tactic may find that organizations face the status quo, not doomsday. Confused? Just the status quo perhaps?
