Post-quantum crypto? #36

Open tomato42 opened 4 years ago

tomato42 commented 4 years ago

My understanding of the protocol is that it currently depends on classical cryptography: FFC or ECC.

Most of algorithms in consideration in the post-quantum selection process do not operate on groups though. With exception of SIKE – Supersingular Isogeny Key Exchange (or SIDH).

Maybe we should consider implementing support for it? (using two algorithms in parallel, like in CECPQ1, may be a good idea)

I agree completely. I suspect any method which supports multi-party key exchange can be made to work.
