We warmly welcome you to SECRYPT 2009 - the International Conference on Security and Cryptography, which is held, this year, in Milan, Italy. This conference reflects a continuing effort to increase the dissemination of recent research among professionals who work on the fields of security and cryptography, especially for the five scientific areas included in the conference. SECRYPT is integrated as one of the modules of the ICETE joint conference. The major goal of ICETE is to bring together researchers, engineers and practitioners interested in information and communication technologies, including e-business, wireless networks and information systems, security and cryptography, signal processing and multimedia applications. These are the main knowledge areas that define the four component conferences, namely: ICE-B, WINSYS, SECRYPT and SIGMAP, which together form the ICETE joint conference. In the program for this joint conference, we have included keynote lectures, papers, and
posters to present the widest possible view on these technical areas. With these tracks, we expect to appeal to a global audience of the engineers, scientists, business practitioners and policy experts, interested in the research topics of ICETE. All tracks focus on research related to real world applications and rely on contributions not only from the Academia but also from the industry, with different solutions for end-user applications and enabling technologies, in a diversity of communication environments. The proceedings demonstrate a number of new and innovative solutions for e-business and telecommunication, and demonstrate the vitality of these research areas. ICETE has received 300 papers in total, with contributions from more than 50 different countries, from all continents, which demonstrates the success and global dimension of ICETE 2009. To evaluate each submission, a double blind paper evaluation method was used: each paper was reviewed by at least two experts from the International Program Committee, in a double-blind review process, and most papers had 3 reviews or more. In the end, 114 papers were selected for oral presentation and publication, corresponding to a 38% acceptance ratio. Of these only 34 were accepted as full papers (11% of submissions) and 80 as short papers. Additionally, 51 papers were accepted for poster presentation. These acceptance ratios demonstrate that ICETE 2009 strives to achieve a high quality standard which we will keep and enhance in order to ensure the success of next year conference, to be held in Milan/Italy. Furthermore, a short list of about 30 papers will be selected to appear in a book that will be published by Springer. We would like to emphasize that SECRYPT 2009 includes outstanding keynote lectures in areas which are very relevant, nowadays. These talks are presented by distinguished researchers who are internationally renowned experts, and contribute to heighten the overall quality of the Conference. A successful conference involves more than paper presentations; it is also a meeting place, where ideas about new research projects and other ventures are discussed and debated. Therefore, a social event including a conference diner was organized for the evening of July 9 in order to promote this kind of social networking. We would like to express our thanks, first of all, to the authors of the technical papers presented at the conference, whose work made possible to put together a high quality program. Next, we would like to thank all the members of the program committee and reviewers, who helped us with their expertise, dedication and time. We would also like to thank the invited speakers for their invaluable contribution, sharing their vision and knowledge. Naturally, a word of appreciation for the work of the secretariat and all other members of the organization, whose diligence in dealing with all organizational issues were essential and required a collaborative effort of a dedicated and highly capable team. We hope that you will find these proceedings interesting and a helpful reference in the future for all those who need to address the areas of e-business and telecommunications.
