Thanks for the prompt feedback! I'll make sure to address these comments in my talk, and I'm looking forward to discussing design options in person. I suspect that the flexibility of the tools and techniques we use as well as the associated engineering and privacy tradeoffs will make for an interesting discussion.

My posted slides will not include many words, so I wanted to share a link to the preprint of our academic paper on the subject in case anyone wants to read the details there. The paper is targeted at a somewhat different audience, but it can be found here: https://arxiv.org/abs/1703.02209 Thanks and looking forward to meeting you all next week! Cool, but I immediately see a problem - you require logs to be in timestamp order, but they aren't. I can't immediately think of a way to get that property without also considerably increasing time to inclusion in the log. That seems undesirable - in fact, we're trying to go the other way, i.e. reduce time to inclusion, in general. Also, engineering reality doesn't change, so increasing time to inclusion is also likely to increase MMD. Secondly, its interesting, but doesn't seem particularly useful: when an SCT corresponds to a cert that has not been included, you want to reveal the cert, not hide it. What you want to hide is who is revealing it. ~saba _______________________________________________ Trans mailing list [email protected]<mailto:[email protected]> https://www.ietf.org/mailman/listinfo/trans
