Good morning to everybody. I am Iliano Cervesato, Program Chair of ASIAN'07 and coordinator of the the conference on the ground. As such, please come to see me, or anybody with a red ribbon on his/her badge, for any question you may have. I already know what the first one is going to be: "how do I get on the Internet?". Connect to the QFLink wireless network and log in as a guest (but use distractions sparingly). Welcome to the 2007 edition of the ASIAN conference, which this year focuses on Computer and Network Security. For the past 12 years, ASIAN has been a forum for researchers throughout Asia to present their work, to discuss advances in the field, and to interact with researchers from other continents. ASIAN'07 has more than fulfilled this mission: we have delegates from 15 countries in this room, most of them Asian. Please make sure to talk to all of them! It is wonderful to see so many of you here, especially since this is the first time that a scientific conference in Computer Science takes place in Qatar. Many of you, like me a couple of years ago, had to look up on a map where exactly Qatar was (and check that it is indeed in Asia), and I hope that, like me, you will be mesmerized by the grandiose experiment in education and research that is taking shape here. We, at Carnegie Mellon University, are proud to be part of it, and we are glad that you too are part of it. In spite of taking place in a little known (for now) corner of Asia, ASIAN'07 has attracted about the same number of submissions (112) as the last edition, in glamorous Tokyo, and out of these, the Program Committee has selected 15 regular and 10 short papers that will be presented in the next 3 days. In addition, 3 of the most influential researchers in computer and network security have graciously accepted to give invited talks. Welcome to ASIAN'07, welcome to Carnegie Mellon University, welcome to Education City, welcome to Qatar!
