Negli ultimi decenni il rapido sviluppo delle tecnologie IT ha influito in maniera determinante nella vita dell'uomo, trasformando, spesso inconsapevolmente il suo lavoro, le sue abitudini, il suo modo di interagire con il mondo che lo circonda. Il fenomeno della "globalizzazione" dei mercati e solo una delle trasformazioni che l'intero pianeta sta attraversando. Anche se i vantaggi derivanti dall'utilizzo delle moderne tecnologie di comunicazione ci facilitano nel lavoro e nella attivita ludiche e personali, molte sono le perplessita e i dubbi che attanagliano tutti coloro che le utilizzano. Se l'Information Technology rappresenta il "combustibile" indispensabile per la sopravvivenza delle aziende e delle attivita dell'uomo, nel contempo puo generare problematicita di grande rilievo. Il testo tratta alcune delle problematiche che destano preoccupazioni rilevanti nel mondo intero come il consumo energetico dei sistemi informatici (incontrollabili e inquinanti), il problema della garanzia della privacy e dell'integrita dei dati su Internet, l'utilizzo della rete Internet come strumento di controllo delle masse, la possibile sparizione degli attuali sistemi operativi che potranno essere sostituiti dal sistema operativo Web Operating System."

It was a pleasure to take part in the 2005 European Workshop on Security and Privacy in Ad Hoc and Sensor Networks (ESAS 2005), held on July 13-14 in Visegrad (Hungary) in conjunction with the First International Conference on Wireless Internet (WICON) . As Program Co-chairs, we are very happy with the outcome of this year's ESAS workshop. It clearly demonstrates the continued importance, popularity andtimeliness oftheworkshop'stopic: securityandprivacy inadhocandsensor networks.Atotalof51fullpapersweresubmitted.Eachsubmissionwasreviewed by at least three expert referees. After a short period of intense discussions and deliberations, the Program Committee selected 17 papers for presentation and subsequent publication in the workshop proceedings. This corresponds to an acceptance rate of 33% - a respectable rate by any measure. First and foremost, we thank the authors of ALL submitted papers. Your con?dence in this venue is much appreciated. We hope that you will continue patronizing ESAS as authors and attendees. We are also very grateful to our colleagues in the research community who served on the ESAS Program C- mittee. Your sel?ess dedication is what makes the workshop a success. Finally, we are very grateful to the ESAS Steering Group: Levente Buttyan, Claude Castelluccia, Dirk Westho? and Susanne Wetzel. They had the vision and the drive to create this workshopin the ?rst place; they also provided many insightsandlotsofhelpwiththisyear'sevent.Weespeciallyacknowledgeand- preciate the work of Levente Buttyan whose dedication (as Steering Committee member, PC member and Local Arrangements Chair) played a very important role in the success of the workshop.

The10thintheseriesofIMAConferencesonCryptographyandCodingwasheld at the RoyalAgricultural College, Cirencester, during 19 21 December 2005. As usual, the venue provided a relaxed and informal atmosphere for attendees to discuss work and listen to the collection of talks. The program consisted of four invited talks and 26 contributed talks. The invitedtalkswheregivenbyTuviEtzion, UeliMaurer, AlfredMenezesandAmin Shokrollahi, and three of these invited talks appear as papers in this volume. Special thanks must go to these four speakers as they helped to set the tone, by coveringall the areasthe meeting aimed to cover, from cryptographythrough to coding. In addition the best speakers are often the hardest to persuade to come to a meeting, as they are usually the most busy. We therefore feel privileged to have had a meeting with four such distinguished speakers. The contributed talks were selected from 94 submissions. This is nearly twice thenumberofsubmissionsforthepreviousmeetingin2003.Thisisanindication of the strength of the subject and the interest in the IMA series of meetings as a venue to present new work. The contributed talks ranged over a wide number of areas, including information theory, coding theory, number theory and as- metric and symmetric cryptography. Subtopics included a number of current hot topics, such as algebraic cryptanalysis and cryptographic systems based on bilinear pairings. Assembling the conference program and these proceedings required the help of a large number of individuals. I would like to thank them all here."

The ?rst SKLOIS Conference on Information Security and Cryptography(CISC 2005) was organized by the State Key Laboratory of Information Security of the Chinese Academy of Sciences. It was held in Beijing, China, December 15-17,2005andwassponsoredbytheInstituteofSoftware, theChineseAcademy of Sciences, the Graduate School of the Chinese Academy of Sciences and the National Science Foundation of China. The conference proceedings, represe- ing invited and contributed papers, are published in this volume of Springer s Lecture Notes in Computer Science (LNCS) series. The area of research covered by CISC has been gaining importance in recent years, and a lot of fundamental, experimental and applied work has been done, advancing the state of the art. The program of CISC 2005 covered numerous ?elds of research within the general scope of the conference. The International Program Committee of the conference received a total of 196 submissions (from 21 countries). Thirty-three submissions were selected for presentation as regular papers and are part of this volume. In addition to this track, the conference also hosted a short-paper track of 32 presentations that were carefully selected as well. All submissions were reviewed by experts in the relevant areas and based on their ranking and strict selection criteria the papers were selected for the various tracks. We note that stricter criteria were applied to papers co-authored by program committee members. We further note that, obviously, no member took part in in?uencing the ranking of his or her own submissions."

Mycrypt 2005 was the inaugural international conference on cryptology hosted in Malaysia. The conference was co-organized by the Information Security - search Lab at Swinburne University of Technology (Sarawak Campus), NISER (National ICT Security and Emergency Response Centre) and INSPEM (Ins- tute for MathematicalResearch)at UPM (UniversityPutra Malaysia).Mycrypt 2005 was held in Kuala Lumpur, Malaysia during September 28-30 2005, in conjunction with the e-Secure Malaysia 2005 convention. Therewere90paper submissionsfrom23 countriescoveringall areasof cr- tologic research, from which 19 were accepted. We would like to extend our thanks to all authors who submitted papers to Mycrypt 2005. Each paper was sentanonymouslytoatleast3membersoftheInternationalProgramCommittee for reviews and comments. The review comments were then followed by disc- sions among the Program Committee. A recipient of the Best Paper Award was also selected after voting among Program Committee members. The winning paper was "Distinguishing Attacks on T-functions" by Simon Kunzli ] (FH A- gau, Swizerland), Pascal Junod (Nagravision SA, Switzerland) and Willi Meier (FH Aargau, Swizerland). These proceedings contain revised versions of all the accepted papers. The conference program included three keynote papers: Hideki Imai (Tokyo University)presenteda paper entitled "TrendsandChallenges forSecurer Cr- tography in Practice."

This volume contains the proceedings of the 8th International Information - curity Conference (ISC 2005), which took place in Singapore, from 20th to 23rd September 2005. ISC 2005 brought together individuals from academia and - dustry involvedin manyresearchdisciplines of information security to foster the exchange of ideas. During recent years this conference has tried to place special emphasis on the practical aspects of information security, and since it passed from being an international workshop to being an international conference in 2001, it has become one of the most relevant forums at which researchers meet and discuss emerging security challenges and solutions. Advised by the ISC Steering Committee, and in order to provide students with more opportunities for publication, ISC 2005 accepted extra student papers - sides the regular papers. The initiative was very well accepted by the young sector of the scienti?c community, and we hope that the success of this idea will remainfornextISCevents. AnotherimportantfactorforthesuccessofISC2005 was that selected papers in the proceedings will be invited for submission to a special issue of the InternationalJournalof InformationSecurity. The result was an incredible response to the call for papers; we received 271 submissions, the highest since ISC events started. It goes without saying that the paper selection process was more competitive and di?cult than ever before - only 33 regular papers were accepted, plus 5 student papers for a special student session.
