 Right, so this this talk has a character both scientific and cultural so I'll start with a scientific part I'll tell you about a recent result. We have with my student Muhammad is second colleague Anna Milanova about optimal MPC mixing What's the general idea? We know that different types of operations like additions and multiplications or Boolean gates are Better faster more efficiently computed by different protocols for example We know that the government circuits are better for computing Boolean operations and and bgw is better for computing our medical so and we could in principle think of Computing a circuit different gates by different protocols But the problem is that these protocols somehow process a different state. We want to do it securely so What we in fact would need to be doing is computing something like this Think of it as a meta-circuit where we have a combination of gates standard gates like addition multiplication Boolean and so on and some conversion gates and This is what we would be trying to do. So let me make a parenthesis now from the scientific part to the cultural part so Many of you have seen Greeks Breaking plates and yelling OPA What you might not know is why we do that The reason we do that and we use exactly this word OPA is to express our excitement About an advancement in a problem known as optimal protocol assignment What is the problem? The problem is figuring out what's the best way of combining protocols Sets that we compute this circuit here as fast as possible and This problem was conjectured to be NP hard What we proved in this work, which is to appear at this upcoming CCS is that actually you can solve it the LP relaxation of this problem has an integral solution and therefore it can be solved efficiently We have an open source optimal protocol mixer And this means that you can take arbitrary protocols or our mixer is independent of the actual implementation So at this point as a Greek, I would just say And this is the Now I'm warmed up for the next talk So We'll be we're gonna be holding a pkc 2020 at the University of Edinburgh. There's something unique about this pkc This is to my knowledge the first conference, which is in the country to be decided yet, so At this point it's we know it's gonna be in the United Kingdom It's yet to be seen where it's gonna be It's gonna be at the informatics forum at the University of Edinburgh The program series a geloski alias and we are co-chairing it the general says are me myself Petros Walden and Marcus Colvais Few words about Edinburgh there is things to do outdoors hiking. It's a beautiful city. It's a UNESCO heritage city and Of course, we have our scouts But you might not know is not we have very stylish cows and we have beaches and You don't even need sunscreen So please submit your best works there Thank you He went so fast that you missed the slide where he said that the submission deadline is the second of November And that it's going to be lovely weather in April, which is one of the driest month in Edinburgh So Edinburgh is a spring in spring is a delight especially in contrast to its winter So now you know
