Hi Paul,


On 8/16/17, 1:55 PM, "Cfrg on behalf of Paul Hoffman" <cfrg-bounces@irtf.org on behalf of paul.hoffman@icann.org> wrote:

>Greetings. I was talking with a colleague this morning about draft-hoffman-c2pq and trying to describe quantum computing for cryptanalysis, and why quantum cryptography is not part of it. Their response should give us pause about our terminology: "So post-quantum cryptography is what we get after quantum cryptography is fully developed?".

The current terminology is fine.   We should just be doing a better job of describing why quantum cryptography is not a viable cybersecurity solution.
