Long Term R&D: PQ security (proposal)

Roadmap
21

Danske Bank in Denmark is also collaborating with IBM on PQ solutions. Sooo, @Jan or JensGroth pls can has update on how much PQ is prioritized? It seems all the energy is put into DeAI, which is cool. But if I don’t have an answer for PQ status when getting companies interested, they might not want a second conversation even as they do understand the potential.

Wanted to follow up on this thread. I remember there was a 2022 milestone on the roadmap towards quantum proofing. Even if it totally fell of the radar, it seems like a great place to show that Dfinity is once again positioned to succeed. I believe the cryptograpers at Dfinity are the best of the best. Certainly we can say that ‘we are well positioned to quantum proof within X timeframe and here is how we propose to do it’.

Thanks @diegop for helping to get a reply if possible.

Another major breakthrough:

  • The first is that Willow can reduce errors exponentially as we scale up using more qubits. This cracks a key challenge in quantum error correction that the field has pursued for almost 30 years.
  • Second, Willow performed a standard benchmark computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion (that is, 10^25) years — a number that vastly exceeds the age of the Universe.

That’s not just an issue that would apply to ICP, but also to any tech solution out there. Looking at it from that perspective, I think ICP would still be a better option than a lot of other tech solutions (considering much of the cybersecurity needed for web 2 is not needed for ICP).

Even some of the top tech solution companies are not fully quantum proof yet. Amazon Web Service is working on it:

While there is no evidence that a quantum computer powerful enough to break the public key cryptography in use throughout AWS exists today, we are not waiting. We would rather put protections in place now to protect the security of our customers’ data into the future.

In this post, we covered how AWS will migrate to PQC as part of our shared responsibility model. We also provided guidance to you on how to start your PQC migration strategy, and what part of that strategy you can expect AWS to provide. The road ahead will present new challenges and new opportunities as the industry performs the migration to new cryptographic algorithms. For additional information, blog posts, and periodic updates on our PQC migration, keep watching the AWS Post-Quantum Cryptography page.
