Hi Martin, As SofĂ­a correctly saw, this is just plain TLS with the "straightforward" DH->KEM and Sig->PQ-Sig substitutions. I, of course, do have another 50 pages on how KEMTLS performs and compare it to these results, but I will save those for another day ;-) Cheers, Thom PQShield Op di 27 ju

Thanks! These results are pretty much in line with expectations. It looks like you don't model packet loss and the effect of that. One concern I have is that increases in the number of packets will significantly increase exposure to loss. 1-(1-p)^n tends to increase quite a bit as n increases.

Thanks for preparing the excerpt; this will be helpful for many use cases. (For the WebPKI, as you already mention, we also need to consider SCTs and realistically crappy networks.) "this is LTE in a city", and "this is what a poor-quality rural 3G link > looks like". But alas, these don't seem t

Imo, we have been measuring handshake time as an indication or performance, but time-to-last-byte or time-to-x%-byte should be used instead. There is nothing wrong with your study Thom. It is pretty detailed and useful. I just think that if these new algos get deployed, we would know if their im
