Hybrid Constructions: The Post-Quantum Safety Blanket

The funny thing about safety blankets is they can double as stage curtains for security theater. Art: CMYKat "When will a cryptography relevant quantum computer exist?" is a question many technologists are pondering as they stare into crystal balls or entrails. Two people I admire recently made a public long bet about that question, with a $5000 donation to charity as stakes.

@soatok One argument for hybrids that came up when looking into PQ signatures at work (for firmware updates specifically) is that they offer a way out when you need to store your keys in an HSM for compliance reasons, but also want to start including PQ signatures (which aren't widely supported in HSMs yet) right now - if only to make sure the joints of your implementation stay oiled.

@23n27 That's a threat model- and use case-specific corner case, not the general case.
