Why quantum safe?

Is there a proof of some kind as to why RLWE is quantum-safe - or is that question nonsensical? (Meaning, "thought quantum-safe given what current quantum circuits can do.") Jimw338 (talk) 23:51, 18 February 2018 (UTC)[reply]

Yes, there is a proof. "Kind-off". See NP-hard problems.

Quotiens are not subrings

The statement: "The sub-ring is typically the finite quotient (factor) ring formed by reducing all of the polynomials in {\textstyle \mathbf {F} _{q}[x]} {\textstyle \mathbf {F} _{q}[x]} modulo an irreducible polynomial {\textstyle \Phi (x)} {\textstyle \Phi (x)}" does not make sense as quotient rings are not subrings. They might be represented by a subring, but there is a mathematical distinction. — Preceding unsigned comment added by 37.120.92.37 (talk) 09:15, 25 May 2018 (UTC)[reply]
