[tor-dev] Post-quantum proposals #269 and #270

2016-08-04 Thread lukep
Great to see the community making progress with post-quantum handshakes. But I'm wondering what's going to happen with Proposals #269 and #270. #269 seems to allow any post-quantum algorithm to be used in the hybrid with NTRUEncrypt and NewHope being specified as two options (presumably other op

I suspect the two known families you "do not want to rule out" are SIDH schemes and LWE schemes with no ring structure, like Frodo. At present SIDH is too slow and LWE keys are too big, but both could improve dramatically over the next several years. Jeff signature.asc Description: This is
