We have accepted 13 long accepted talks and seven short talks, the total number of invited talks of 15 and the number of reviews generated, the amount of comments generated by the reviewers was 295, so we do actually do something in the committee to work out who should talk or not. The selection criteria are not whether it's academically whizzy. The selection criteria is whether we think it's of interest to you, the novelty, the timeliness and the quality of the speaker. So hopefully the speakers will live up to our confidence in them. The Contributed Talks Committee is there with the Chair, Dan Bonnet, who marshaled all of these reviews, so please thank Dan. OK, so that's all the things that are different. What are the same? Well, the same will be. We will be giving out the Levshin Prize, which will be given to two people who deserve a prize for their work in real world crypto. Please turn up today at 12 o'clock because you never know you might be the winner. OK. Then on Thursday we have lightning talks, actually the time might have changed, I'm not quite sure. You queue up to give a pitch. Basically there is no slides, you queue up to give a pitch. The only thing you can rely on is your wits and charisma, so that's what you have for the lightning talks. And to keep it current and timely, we've scheduled at the last minute a special talk on Thursday about Spectre and Meltdown, which we thought you might be interested in, which is why this lightning talk session is a bit shorter. Real world crypto 2019 will be in the Bay Area, likely to be San Jose. Everyone knows East Coast, West Coast, Europe, East Coast, West Coast, Europe unless we have a very good reason for not doing. We are currently seeing the Real World Crypto website for suggesting invited speakers. There's a link there for suggesting winners of the Levshin Prize. There will be details of the contributed talks procedure, which will come soon to set things up. Speakers, please beware. This venue is often a rock venue. People who have played here are ACDC, Black Sabbath, Red Hot Chili Peppers, Amy Winehouse. So please make your presentations just as good. There's no crowd surfing allowed. We'll kick people out if they do crowd surfing. So let's rock. Actually no, let's encrypt. So finally, from me, we want to thank once again, Anya and Amelia, because they did shed loads of the work. So Anya and Amelia, could you just stand up so everyone knows who you are? And with that, I hand you over to Anya. OK, thanks and also I welcome everyone to Google with Crypto and to Zurich. And I actually would also like to share the thanks with some more people. So from Google we had Bartosz Szyddartysz Stadec. And from IBM Young Communist to help. And I'm given that was the first event. It was also an ISCR event. It was also of course very cool to have the president of the ISCR sitting on the same floor and helping with any issues regarding that as well. So also thanks to Christian Kosheng for his help. I mean I should already gave you now the most important part of the local information about the rock history. Also the Wi-Fi, I think you have heard it's RWCAS because we had to have an eight character password. Coffee breaks will be outside onto floors and the lunches are going to be in dedicated rooms upstairs. So we will have a bit more room. We will have all the rooms up from tomorrow. Today we have one room less. And we also have reserved small meeting room upstairs. So if you go up there is a door to the right. If you want to just meet people, discuss some new crypto ideas, you can go there and hang out and don't have to do that in the back of the auditorium. We also have a welcome reception today right after the last session in the foyes outside. So that's about some more local information. In terms of social media please tweet about the event. I think a lot of people already have started that and it was kind of interesting to follow how the people were coming into Zurich. Please use the hashtag real world crypto and not RWC because that is more well known as a rugby world cup and I think we will not be able to change that. Videos will be streamed and also later on put on the YouTube channel. I hope it works so just go to the YouTube channel of real world crypto and the live stream should appear there at the first video. It also means if you are a speaker and you do not want to be recorded and or streamed please come to either Emilia or me or send us an email before that so we can turn the video off. Also speakers please send us your slides if you want to have them on the presentation laptop sometime in advance just we have some time to put it there. And also send them I think to Nigel if they should be on the website so we just have clear records if they should be on the presentation laptops or on the website. And also if you're a speaker please come in a bit earlier to the front so we can mic you up and then set everything up. And yeah I think that's it from my side I think I speak for everyone for the local organization comment is such a great feeling that after almost two years of organizational work to see the event being started to seeing people flying in from all over the world. It's just a really cool feeling and I hope you have a great time and yeah so let's get the real crypto started and I think for the first time now we have the slides with all the sponsors and yeah let's just thank them once again for their support. All right so let's get the show on the road so we're going to start our first session on key management services. I guess before we start I just want to repeat the announcement that we're always looking for proposals for invited talks. There's a permanent link on the RwC website so if you have ideas for who we should invite just go and nominate them so A should nominate B and you know we'll take that seriously into consideration. All right so with that let's get started with the actual program so we will start with the key management key management services session and our first speaker is Shai Giron from Amazon who is going to talk about AWS key management services. Shai all yours.
