Google warns quantum computers could hack encrypted systems by 2029 (www.theguardian.com)

Banks, governments and technology providers need to be prepared for quantum computer hackers capable of breaking most existing encryption systems by 2029, Google has warned.

The tech company said in a blogpost that quantum computers would pose a “significant threat to current cryptographic standards” before the end of the decade and urged other companies to follow its lead.

The company, owned by Alphabet, said: “The encryption currently used to keep your information confidential and secure could easily be broken by a large-scale quantum computer in coming years.”

As it stands, quantum computers – which can rapidly carry out complex tasks – are a nascent technology with great potential and significant obstacles to being widely usable.

Tell us something we didn’t know google, turns out there’s people out there that already devising solutions for this problem but your already know that

I mean, they specifically point to post-quantum cryptography and advise people to move towards it in the article:

Google said: “We’ve adjusted our threat model to prioritise post-quantum cryptography migration for authentication services – an important component of online security and digital signature migrations. We recommend that other engineering teams follow suit.”

The issue here is not that there aren't solutions; it's that organizations are not interested in taking the time and effort to move towards them. I've been beating this particular drum at my org for about a year, and I've gotten zero traction. This is a concern because moving to New encryption means taking all the data you've got, decrypting it, and re-encrypting it. That's not fast when you're talking hundreds of terabytes.

Fairly not super experienced on things. but how viable is a layered system, does it just prohibitively slow or storage consuming or is it moderately feasible to say double encapsulate everything.

Huh, interesting; that's a good question. I'm not actually sure about that; it'd be a good thing for me to dig into more. Thanks for the thought!
