These proceedings contain the papers selected for presentation at the 13th European Symposium on Research in Computer Security--ESORICS 2008--held October 6-8, 2008 in Torremolinos (Malaga), Spain, and hosted by the University of Malaga, C- puter Science Department. ESORICS has become the European research event in computer security. The symposium started in 1990 and has been organized on alternate years in different European countries. From 2002 it has taken place yearly. It attracts an international audience from both the academic and industrial communities. In response to the call for papers, 168 papers were submitted to the symposium. These papers were evaluated on the basis of their significance, novelty, and technical quality. Each paper was reviewed by at least three members of the Program Comm- tee. The Program Committee meeting was held electronically, holding intensive d- cussion over a period of two weeks. Finally, 37 papers were selected for presentation at the symposium, giving an acceptance rate of 22%.

This book contains the best papers of the 4th International Conference on E-business and Telecommunications (ICETE), which was held during July 28-31, 2007 in Barcelona, Spain. The conference reflects a continuing effort to increase the dissemination of recent research results among professionals who work in the areas of e-business and telecommunications. ICETE is a joint international conf- ence integrating four major areas of knowledge that are divided into four cor- sponding conferences: ICE-B (International Conference on e-Business), SECRYPT (International Conference on Security and Cryptography), WINSYS (International Conference on Wireless Information Systems) and SIGMAP (International Conf- ence on Signal Processing and Multimedia). The program of this joint conference included several outstanding keynote lectures presented by internationally renowned distinguished researchers who are experts in the various ICETE areas. Their keynote speeches contributed to the ov- all quality of the program and heightened the significance of the theme of the conference. The conference topic areas define a broad spectrum in the key areas of- business and telecommunications. This wide view has made it appealing to a global audience of engineers, scientists, business practitioners and policy experts. The papers accepted and presented at the conference demonstrated a number of new and innovative solutions for e-business and telecommunication networks and systems, showing that the technical problems in these fields are challenging, related and significant.

These are the proceedings of IPTComm 2008 - the Second Conference on Pr- ciples, Systems andApplications ofIP Telecommunications-heldinHeidelberg, Germany, July 1-2, 2008. The scope of the conference included recent advances in the domains of convergent networks, VoIP security and multimedia service environments for next generation networks. The conference attracted 56 s- missions, of which the Program Committee selected 16 papers for publication. The review process followed strict standards: each paper received at least three reviews. We would like to thank all Program Committee members and external reviewers for their contribution to the review process. The conference attracted attendees from academia and industry. Its excellence is re?ected in the quality of the contributed papers and invited talks. Additional industry talks and - plied demonstrations assured a synergy between academic and applied research.

th It is our great pleasure to present this volume of the proceedings of the 10 edition of Information Hiding (IH 2008). The conference was held in Santa Barbara - the Ame- can Riviera, California, USA, during May 19-21, 2008. It was organized by three Santa Barbarans on fire, from both industry (Mayachitra) and academia (UCSB). Over the years, Information Hiding (IH) has established itself as a premier forum for presenting research covering various aspects of information hiding. Continuing the tradition, this year, we provide a balanced program including topics such as anonymity and privacy, forensics, steganography, watermarking, fingerprinting, other hiding domains, and novel applications. We received a total of 64 papers from all over the globe, and would like to take this opportunity to thank all the authors who submitted their paper to IH 2008 and thus contributed to the consolidation of the reputation of the conference. The papers were refereed by at least three revi- ers who provided detailed comments, which was followed by discussion amongst the Program Committee members. Only 25 papers were selected for presentation. This rigorous review process will certainly strengthen Information Hiding's po- tion as the top forum of our community.

The Pairing 2008 Conference was held at Royal Holloway, University of London during September 1-3, 2008. This conference followed on from the Pairing in Cryptography workshop (held in Dublin, Ireland on June 12-15, 2005) and the Pairing 2007 conference (held in Tokyo, Japan on July 2-4, 2007, with proce- ings published in Springer's LNCS 4575). The aim of this series of conferences is to bring together leading researchers and practitioners from academia and industry, all concerned with problems related to pairing-based cryptography. The programme consisted of 3 invited talks and 20 contributed papers. The invitedspeakerswereXavierBoyen(VoltageSecurity, USA), FlorianHess(Te- nical University Berlin, Germany) and Nigel Smart (University of Bristol, UK). Special thanks are due to these speakers, all three of whom provided papers which are included in these proceedings. The contributed talks were selected from ?fty submissions. The accepted papers cover a range of topics in mathematics and computer science, including hardwareand softwareimplementation of pairings, cryptographicprotocols, and mathematical aspects and applications of pairings. We would like to thank all the people who helped with the conference p- gramme and organisation. First, we thank the Steering Committee for their guidance and suggestions. We also heartily thank the Programme Committee and the sub-reviewers listed on the following pages for their thoroughness d- ing the review process. Each paper was reviewed by at least three people and there was signi?cant online discussion about a number of papers.

Information and communication technologies are advancing fast. Processing speed is still increasing at a high rate, followed by advances in digital storage technology, which double storage capacity every year. Furthermore, communication techno- gies do not lag behind. The Internet has been widely used, as well as wireless te- nologies. With a few mouse clicks, people can communicate with each other around the world. All these advances have great potential to change the way people live, introducing new concepts like ubiquitous computing and ambient intelligence. Technology is becoming present everywhere in the form of smart and sensitive c- puting devices. They are nonintrusive, transparent and hidden in the background, but they collect, process, and share all kinds of information, including user beh- ior, in order to act in an intelligent and adaptive way. These emerging technologies put new requirements on security and data m- agement. As data are accessible anytime anywhere, it becomes much easier to get unauthorized data access. Furthermore, the use of new technologies has brought about some privacy concerns. It becomes simpler to collect, store, and search personal information, thereby endangering people's privacy. Therefore, research in secure data management is gaining importance, attracting the attention of both the data management and the security research communities. The intere- ing problems range from traditional topics, such as, access control and general database security, via privacy protection to new research directions, such as cryptographically enforced access control.

On behalf of the IEEE Communications Society, Technical Committee on N- work Operations and Management (CNOM), Manweek 2008 Organizing C- mittee, and members of the IPOM Technical Program Committee, it is our pleasureto present the proceedings of the 8th IEEE Workshop on IP Operations and Management(IPOM 2008),heldaspartofManweek2008duringSeptember 22-26, 2008, on Samos, Greece. ThecurrentInternetisalarge-scaledistributedsystemwhosesub-components suchasaddressing,protocols,algorithms,services,need to scalein time withthe rapid growth of Internet tra?c volumes. Moreover, there is a high level of int- action between di?erent subcomponents of the Internet sometimes in undesired ways - for example, denial of service attacks can jeopardize the operation of a commercial network. With these challenges in place, operations and mana- ment of IP networks have become increasingly important. This necessitates a good understanding of the emerging technical and scienti?c problems in the current Internet, and lessons from such understanding will be particularly - portant for future Internet design and management. Building on the success of the previous events, we wanted IPOM 2008 to focus on network management challenges for the current Internet as well as on future Internet design.

It is a pleasure to welcome you to the proceedings of the second International Castle Meeting on Coding Theory and its Applications, held at La Mota Castle in Medina del Campo. The event provided a forum for the exchange of results and ideas, which we hope will foster future collaboration. The ?rst meeting was held in 1999, and, encouraged by that experience, we now intend to hold the meeting every three years. Springer kindly accepted to publish the proceedings volume you have in your hands in their LNCS series. The topics were selected to cover some of the areas of research in Coding Theory that are currently receiving the most attention. The program consisted of a mixture of invited and submitted talks, with the focus on quality rather than quantity. A total of 34 papers were submitted to themeeting.Afteracarefulreviewprocessconductedbythescienti?ccommittee aided by external reviewers, we selected 14 of these for inclusion in the current volume, along with 5 invited papers. The program was further augmented by the remaining invited papers in addition to papers on recent results, printed in a separate volume. We would like to thank everyone who made this meeting possible by helping with the practical and scienti?c preparations: the organization committee, the scienti?c committee, the invited speakers, and the many external reviewers who shall remain anonymous. I would especially like to mention the General Advisor ofthe meeting, OyvindYtrehus.Finally Iextend mygratitudeto allthe authors and participants who contributed to this meeting."

This volume contains the proceedings of the 12th Financial Cryptography and DataSecurityInternationalConference, heldinCozumel, Mexico, January28-31 2008. Financial cryptography (FC) and data security has been for years the main international forum for research, advanced development, education, exploration, and debate regarding information assurance in the context of ?nance and commerce. Despite the strong competition from other top-tier related security conf- ences, the Program Committee received a signi?cant number of submissions, indicating a growingacceptance of FC as the premier ?nancialand data security forum. The ProgramCommittee, led by the PCChair Gene Tsudik, achievedan excellent program balance between research, practice, and panel sessions. This year the program included two new additions, namely, a short-paper track and a poster session, both extremely well received. Intimate and colorful by tradition, the high-quality program was not the only attraction of FC. In the past, FC conferences have been held in highly research-synergistic locations such as Tobago, Anguilla, Dominica, Key West, Guadeloupe, Bermuda, and the Grand Cayman. In 2008 we continued this t- dition and the conference was located in sunny Cozumel, Mexico. The ongoing carnival, sailing, submarine trips, and Mayan ruins were just a few of the - merous exciteme

Since1994, CARDIShasbeentheforemostinternationalconferencededicatedto smart card research and applications.

This year's CARDIS was held in London, UK, on September 8-11, 2008. It was organized by the Smart Card Centre, Information Security Group of the Royal Holloway, University of London. Thepresentvolumecontainsthe21papersthatwereselectedfromthe51s- missions to the conference. The 22 members of the program committee worked hard in order to evaluate each submission with at least three reviews and agree on a high quality ?nal program. Additionally, 61 external reviewers helped the committee with their expertise. Two invited talks completed the technical p- gram. The ?rst one, given by Ram Banerjee and Anki Nelaturu, was entitled "Getting Started with Java Card 3.0 Platform." The second one, given by Aline Gouget, was about "Recent Advances in Electronic Cash Design" and was c- pleted by an abstract provided in these proceedings.

Many people do not realise that mathematics provides the foundation for the devices we use to handle information in the modern world. Most of those who do know probably think that the parts of mathematics involvedare quite 'cl- sical', such as Fourier analysis and di?erential equations. In fact, a great deal of the mathematical background is part of what used to be called 'pure' ma- ematics, indicating that it was created in order to deal with problems that originated within mathematics itself. It has taken many years for mathema- cians to come to terms with this situation, and some of them are still not entirely happy about it.

I have tried to cover each of these three areas in su?cient depth so that the reader can grasp the basic problems and go on to more advanced study.

A course in elementary abstract algebra and/or number theory would be helpful, but the book contains the essential facts, and readers without this background should be able to understand what is going on. vi Thereareafewplaceswherereferenceismadetocomputeralgebrasystems.

These are the proceedings of WAIFI 2008, the second workshop on the Ari- metic of Finite Fields, that was held in Siena, Italy, July 6-9, 2008. The ?rst workshop, WAIFI 2007, which was held in Madrid (Spain), was received quite enthusiasticallybymathematicians, computerscientists, engineersandphysicists who are performing research on ?nite ?eld arithmetic. We believe that there is a need for a workshop series bridging the gap between the mathematical theory of ?nite ?elds and their hardware/software implementations and technical - plications. We hope that the WAIFI workshopseries, which from now on will be held on even years, will help to ?ll this gap. Therewere 34 submissionsto WAIFI 2008, of which the ProgramCommittee selected 16 for presentation. Each submission was reviewed by at least three reviewers. Our thanks go to the Program Committee members for their many contributionsandhardwork.Wearealsogratefultotheexternalreviewerslisted below for their expertise and assistance in the deliberations. In addition to the contributions appearing in these proceedings, the workshop program included an invited lecture given by Amin Shokrollahi. Special compliments go out to Enrico Martinelli, General Co-chair, and to Roberto Giorgi and Sandro Bartolini, local organizers of WAIFI 2008, who broughtthe workshopto Siena, oneofthe mostbeautiful citiesofTuscany, Italy. WAIFI 2008 was organized by the Dipartimento di Ingegneria dell'Informazione of the University of Siena, Italy. The submission and selection of papers were done using the iChair software, developed at EPFL by Thomas Baign eres and Matthieu Finiasz. We also thank Deniz Karakoyunlu for his help in this matter.

ICITS 2008, the Third InternationalConference on Information Theoretic Se- rity, was held in Calgary, Alberta, Canada, during August 10-13, 2008, at the Universityof Calgary.This seriesof conferences wasstarted with the 2005IEEE InformationTheoryWorkshoponTheoryandPracticein Information-Theoretic Security (ITW 2005, Japan), held on Awaji Island, Japan, October 16-19,2005. The conference series aims at bringing focus to security research when there is no unproven computational assumption on the adversary. This is the fra- work proposed by Claude Shannon in his seminal paper formalizing modern unclassi?ed research on cryptography. Over the last few decades, Shannon's approach to formalizing security has been used in various other areas including authentication, secure communication, key exchange, multiparty computation and information hiding to name a few. Coding theory has also proven to be a powerful tool in the construction of security systems with information theoretic security. Therewere43submitted papers ofwhich14wereaccepted.Eachcontributed paper was reviewed by three members of the Program Committee. In the case of co-authorship by a Program Committee member the paper was reviewed by ?ve members of the committee (no committee member reviewed their own s- mission). In addition to the accepted papers, the conference also included nine invited speakers, whose contributions were not refereed. These proceedings c- tain the acceptedpapers with anyrevisionsrequiredbythe ProgramCommittee as well as the contributions by invited speakers.

The AFRICACRYPT 2008 conference was held during June 11-14, 2008 in Casablanca, Morocco. Upon the initiative of the organizers from the Ecole n- male sup erieure in Casablanca, this event was the ?rst international research conference in Africa dedicated to cryptography. The conference was honored by the presence of the invited speakers Bruce Schneier, Jacques Stern, and Alexander W. Dent who gave talks entitled "The Psychology of Security" "Modern Cryptography: A Historical Perspective" and "ABriefHistoryofProvably-SecurePublic-KeyEncryption,"respectively.These proceedings include papers by Bruce Schneier and by Alexander Dent. The conference received 82 submissions on November 24, 2007. They went through a careful doubly anonymous review process. This was run by the iChair software written by Thomas Baign eres and Matthieu Finiasz. Every paper - ceived at least three review reports. After this period, 25 papers were accepted on February 12, 2008. Authors then had the opportunity to update their papers until March 13, 2008. The present proceedings include all the revised papers. At the end of the review process, the paper entitled "An Authentication Protocol with Encrypted Biometric Data" written by Julien Bringer and Herv e Chabanne was elected to receive the Africacrypt 2008 Best Paper Award.

Since the mid 1990s, data hiding has been proposed as an enabling technology for securing multimedia communication, and is now used in various applications including broadcast monitoring, movie fingerprinting, steganography, video indexing and retrieval, and image authentication. Data hiding and cryptographic techniques are often combined to complement each other, thus triggering the development of a new research field of multimedia security. Besides, two related disciplines, steganalysis and data forensics, are increasingly attracting researchers and becoming another new research field of multimedia security. This journal, LNCS Transactions on Data Hiding and Multimedia Security, aims to be a forum for all researchers in these emerging fields, publishing both original and archival research results.

This second issue contains five papers dealing with a wide range of topics related to multimedia security. The first paper introduces Fingercasting, which allows joint fingerprinting and decryption of broadcast messages. The second paper presents an estimation attack on content-based video fingerprinting. The third proposes a statistics and spatiality-based feature distance measure for error resilient image authentication. The fourth paper reports on LTSB steganalysis. Finally, the fifth paper surveys various blind and robust watermarking schemes for 3D shapes.
