National security memo warns that quantum computing could jeopardize civilian and military communications, and defeat security protocols for most Internet-based financial transactions
The U.S. government is barreling ahead with plans to mitigate future threats from quantum computing with a new White House memo directing federal agencies to jumpstart an all-hands-on-deck approach to migrating to quantum-resistant technologies.
The security memo, released alongside a plan to promote U.S. leadership in quantum computing, directs specific actions for agencies to take during what is being described as a laborious, multi-year process of migrating vulnerable computer systems to quantum-resistant cryptography.
"Research shows that at some point in the not-too-distant future, when quantum computers reach a sufficient size and level of sophistication, they will be capable of breaking much of the cryptography that currently secures our digital communications on the Internet," the government warned.
Noting that quantum computing poses “significant risks to the economic and national security of the United States,” the White House cautioned that a quantum computer of sufficient size and sophistication “will be capable of breaking much of the public-key cryptography used on digital systems across the United States and around the world.”

Wonder what they are not telling us?
No such thing, but keep warning about those shadows on the wall.
Quantum computing is very close. Most conservative estimates say by the end of this decade, easy.
Most modern security is based around very good cryptographic science, but for a supercomputer, even complex passwords could be cracked in less than a day. For ciphers under AES128, most modern, somewhat common, security configurations are based on crypto from 2012.
If quantum computing is achieved near term, those systems could be breached in days if not hours. This is to jumpstart government spending on IT cyber services. It works very well under the Dems.

Quantum computers are a million times too small to hack bitcoin
Bitcoin is theoretically vulnerable to being cracked by quantum computers, but calculations show they would need to be a million times larger than those that exist today

Damm. Thanks for posting. Just changed my passwords from “password” to “password123”....That should slow them down.
For about a micro, micro second.
Seems like its a good time to use something like a “yubico” security key such that one needs to insert a physical USB device in order to log onto their financial site.
Probably that the Chinese are leaps and bounds ahead of us in quantum computing technology because they employ actual computer scientists to do research instead of woke social justice warriors.
I was talking more enterprise security than cryptographic hashing. There’s a lot more going on with cryptocoin than people often understand.
Seems like the company that manufactures your key could make their own back door, but I am a little paranoid since Covid. All our home security systems require us to install an app to activate the cameras, wonder what else that app does?
The bad news is that quantum machines are way more error-prone than classical computers because of decoherence.

From what I’ve seen, mostly they’ll just have to change the ciphers accepted by encrypted connections. Some of the currently used ones are theoretically vulnerable.

Nope, they ain’t. They’re a couple of years behind.
