 Wow, it's so loud. Good morning. Welcome to AsiaCrip 2017 and welcome to Hong Kong. I know that everybody is coming from all different places, different countries and regions. And it's so thrilled for us to have this chance to organize this one, this year's event. And this is actually our privilege. This is the first time organizing AsiaCrip in Hong Kong. So whenever you need, please let us know. I'm Duncan. And also we have another general co-chair, Xiumen, and also our local chair, Lucas. We are all here for serving you guys, and we hope that you have a great stay in Hong Kong and have this great event. So to start with, I know a lot of people are coming from different places having this long haul flight, or having the jet lag, especially friends from Europe. You guys should be sleeping. So we would like to start with something which is special to wake everybody up. And also it's a Chinese culture, or especially a Hong Kong culture. It's to have the lion dance performance as an opening ceremony. So I hope that you like it. And actually if you look at the back, you will already be able to see the lion hat over there. So let's welcome this lion dance performance. And thank you, everybody. As a photographer, probably we will be able to decipher. Thank you, thank you very much. It's to have our program co-chair, Xiumen, to give us an opening remark. Xiumen, please. Welcome to AsiaCrip 2017. I'm Xiumen Kochiari. This is AsiaCrip 2017 with Thomas Belland. So this is a 23rd annual international conference on theory and application of cryptography and information security. So this conference focuses on all technical aspects of cryptology and international association for cryptographic research, ICL. So AsiaCrip 2017 received 243 submissions. And from all over the world, the program committee selected 67 papers for presentation in this conference. And we thank all 48 program committees and as well as 334 external reviewers from their fruitful comments and discussion on their areas of expertise. And so the program of AsiaCrip 2017 featured three excellent invited talks. So Dr. Dustin Moody will talk about the NIST postcomptom cryptography competition. And Dr. Kwon Shun-guang will give a talk on combinatorics in information security. And so Dr. Pascal Payet will give a talk about white box cryptomania. So we are greatly indebted to the general co-chair, Duncan Wang, and Sumin Yi, and for their effort and for our organization. Thank you very much. And we also like to thank local organizing committee. So many members have helped this conference for the success. So thank you very much. Okay, finally, I hope that you will enjoy the talks and events at AsiaCrip 2017. Thank you very much. Thank you, Sumin Yi. So next, our general co-chair, Sumin Yi, is going to give us some of the statistical data. And also to have just a little remark and also some detailed information about the coming few days plans. And after that, we are going to have the invited talk. Okay, good morning. So you can see that because, you know, the two sides cannot see clearly. So we benefit them first. They can see this screen first. So we will wait for this to come up. Okay, so welcome to AsiaCrip and Hong Kong at the end. So Duncan, and I'm SM. Okay, so we have about 255 registrations and they actually come from 31 many different countries. Okay, you can see the list. I don't want to spend time on that. Anyway, okay. So we have 157 and 98 student registrations. And also we would like to thank the IACL to support the student speakers with the registrations waited. And we also give some stipends. Okay, so that's general information. But here the coming up will be very important. So I want to give some important announcement first. Now for the Wi-Fi password, we have two categories. If you stay in the hotel, basically you can use your hotel room password. If you look at the notice around the conference venue, you can see the SSID. But on the other hand, if you are not staying in this hotel, then you can try to join another SSID and using a different password so that we can make sure that the Wi-Fi is smooth. So if you want information, I think they post on the conference venue already for the password. Okay, for the proceedings, actually we put the link up a few days ago already. So it's available online. And if you haven't got it and want to get it, and if you cannot get it for more than nine, you still can approach any of our helpers. They are carrying a USB with the proceedings inside and then they will have to copy it. Okay, now we are going to, this is even more important, the logistics. You probably, if you are the first time to Hong Kong, you start to feel that Hong Kong is really small. But on the other hand, you can get anything, very nearby, food, drink, bar, whatever. So anyway, the logistics is very important. We are going to have a group photo after the first section at 10.50. And the group photo will be just here. We will try to let you just stand at the back a little bit and then we will take the photo here. Okay, so it's at 10.50 to pay. A coffee bag also very dear, right behind. Okay, so the coffee bag also in this conference hall. And for the lunch, go to the second floor. Okay, and for the beaver, an arranged, okay. But you can see that actually we are at the right at the center of the city. So you can go anywhere to get the type of food you like. Okay, many restaurants around. You can also travel through the MPL, to the shopping mall, whatever. Okay, it's the same here, okay. And of course we are going to have a banquet on Wednesday. But please pay attention, the banquet is not in the hotel. Okay, it's after the tour. So actually we have transportation for you to go to the banquet venue. But don't worry right now, okay. I assume that you won't go away, right. So you stay in the conference. We will try to give you an announcement on Tuesday, Wednesday, so that you won't miss it. And of course we have a wetland tour on Wednesday afternoon, right after lunch. So we still have the lunch in the hotel. Okay, after lunch, then we have transportation for you to go to the tour. And then at that spot, then we have another transportation for you to go to the banquet venue. Okay, so you just don't worry. Pay attention to our announcement. And you know, if you have any questions, ask us or any of the helpers. Okay, this is important. Rum section, traditions, right, for Asia create. So we'll be back tomorrow night, okay. Again in the same window here, okay. But then we need more funny talks, okay. So if you want to talk in the rum section, we have a deadline. Tomorrow 5 p.m., try to send an email with a slide to us in this address. With the title rum section, we try to arrange it, okay. Now if it's too boring, we'll stop you right away, okay. Try to make it more funny, okay. Now and then, you know, our original plan is to have the conference in the campus. But then, you know, Hong Kong is having big renovation for the classroom. So that's why we move it to here. So we are very tight in schedule. So section chair and speaker, please help. Do not overrun, okay. Try to keep the time tight. And then we do have some sign to notify you that you only have five minutes, et cetera. Okay, so now here are some more important notice. Because in the hotel, they may have other activities. So you remember to wear your badge all the time when you're in the conference. And secondly, keep your personal belongings. This is not the campus, okay. So keep your own belongings with you all the time. So we do not have locker. We do not have, you know, people to help you to keep your luggage. Okay, try to keep them with you all the time. And if you need some hotel information, emergency contact person number, actually it's inside your badge. Okay, you take it out. The inside, we have those information. Okay, and then number four, if you look at the souvenir, we have a 3D postcard, okay, of Hong Kong. And okay, postcard, usually you want to mail it back, right? Okay, so our organizing team is very, very nice. They actually arrange a postbox at the reception. So you just stick to write down the address and the one you want to mail. And then put it there. You don't need to put it in stamp. We will help you, okay? But you know, if you want to write a love letter to your girlfriend or boyfriend, because it's not here, then you cannot do it, okay? It's only for postcard. Okay, all right? Yeah, only for any postcard. Not for any postcard. Only for that 3D souvenir postcard, okay? And then we will try to, the deadline for you to put the postcard there is like 1pm the last day, 7. Okay? Then we will try to help you to mail it out. And finally, I want to also say thank you, a lot of party like IACL, all the members of the organizing team, especially Lucas, I think he's hiding over there. And Kathy, you see a young lady, you know, running back and forth. I don't know where she is now. You need to recognize her because if you need more information, you need to approach her. Kathy, are you around? She's hiding too. I don't know why. Oh, it's coming. Okay? So you need to recognize her, okay? So if you want any special needs, approach her, okay? And of course, all the student helpers, you know, there are many, many there. And if you have any, if you want any information, you also talk to them. For example, if I want to buy, you know, expensive handbag for my girlfriend, ask them. We don't know. We don't know, right? No idea. We have no idea, okay? But they have ideas. Okay, ask them. And okay, also, of course, we'd like to thank the PC chair, PC members, and our sponsor, Intel, Spangler, Hong Kong Tourism Board. And of course, we need to thank all the participants here. Without you, the conference will not be that successful. And more importantly, enjoy the conference and you'll stay in Hong Kong. Okay? Thank you very much. And also one more thing is that this humble is very important because it also contains the address of the banquet and also the time for the pickup because we actually arranged some coaches versus for picking everybody up to the banquet. Okay. So next, we are going to start right away into this invited lecture. So we will have the session chair. So Yoshi come again to run this section. So Yoshi-san, please.
