Most cryptographers think we will see RSA and EC type public key code breaking at least for small keys (<=1024 for RSA, <256 for EC) within 10-15 years. Once that happens we can more or less consider classical asymmetric crypto unsafe since we can assume deep-pocketed adversaries (NSA, FSB, China, etc.) may be ahead of what is publicly disclosed. That's why classically computable but quantum resistant asymmetric cryptography is one of the hottest areas of crypto research right now.
- benlivengood 6y agoDoes anyone really think the deep pockets of the TLAs haven't already done at least this well, especially with photonics at least? All the theoretical fundamentals have been known for decades. If COTS parts can do this then a focused research program begun decades ago will have already achieved what is public today. Public demonstration to me is just a proof-of-concept validating that state actors achieved parity with it quite a while ago.

It would only be pulled out and used in extreme cases for fear of accidentally revealing evidence of its existence by breaking a code that one should not be able to break (similar to how the allies in WWII let the Germans sink a few ships rather than reveal that they could break German codes).
