The First International Conference on Digital Rights Management: Technology, Issues, Challenges and Systems (DRMTICS - pronounced 'dramatics'), took place in Sydney, Australia on 31st October - 2nd November, 2005. It was or- nized by the Centre for Information Security of the University of Wollongong and in cooperation with the International Association of Cryptologic Research (IACR) and IEEE Computer Society's Task Force on Information Assurance. DRMTICS isan internationalconferenceseriesthat coversthe areaof digital rights management, including research advancements of an applied and theor- ical nature. The goal is to have a broad coverage of the ?eld and related issues and subjects as the area evolves. Since the Internet and the computing infr- tructure has turned into a marketplace for content where information goods of various kinds are exchanged, this area is expected to grow and be part of the ongoing evolution of the information society. The DRM area is a unique blend of many diverse disciplines that include mathematics and cryptography, legal and social aspects, signal processing and watermarking, game theory, infor- tion theory, software and systems design and business analysis, and DRMTICS attempts to cover as much ground as possible, and to cover new results that will further spur new investigations on the foundations and practices of DRM. We hope that this ?rst conference marks the beginning of a fruitful and useful series of future conferences. This year, the conference received 57 submissions out of which 26 were - cepted for presentation after a rigorous refereeing process.

Many malicious attacks are achieved by malicious code or malware, such as viruses and worms. Shared resources, such as the Internet, have created a highly interconnected cyber-infrastructure. Critical infrastructures in domains such as medical, power, telecommunications, and finance are highly dependent on information systems. These two factors have exposed our critical infrastructures to malicious attacks and accidental failures. Given the deleterious affects of malware on our cyber infrastructure, identifying malicious programs is an important goal. Unfortunately, malware detectors have not kept pace with the evasion techniques commonly used by hackers--the good guys are falling behind in the arms race.Malware Detection, based on the Special ARO/DHS Workshop on Malware Detection at Rosslyn, VA, in 2005, captures the state of the art research in the area of malicious code detection, prevention and mitigation.This edited volume is intended for researchers and developers working on malicious code (malware) detection, prevention and mitigation. In addition it can be used for a senior level undergraduate course, or for a graduate course in the area of computer and software security.

This volume contains the refereed proceedings of the 3rd International Conf- ence on Sequences and Their Applications (SETA 2004), held in Seoul, Korea during October 24-28, 2004. The previous two conferences, SETA 1998 and SETA 2001, were held in Singapore and Bergen, Norway, respectively. These conferences are motivated by the many widespread applications of sequences in modern communication systems. These applications include pseudorandom sequences in spread spectrum systems, code-division multiple-access, stream ciphers in cryptography and several connections to coding theory. The Technical Program Committee of SETA 2004 received 59 submitted - pers, many more than the submissions to previous SETA conferences. The C- mittee therefore had the di?cult task of selecting the 33 papers to be presented at the Conference in addition to four invited papers. The authors of papers p- sented at the conference were invited to submit full papers that were refereed before appearing in this proceedings. These proceedings have been edited by the Co-chairs of the Technical P- gram Committee for SETA 2004: Tor Helleseth of the University of Bergen, Norway, and Dilip Sarwate of the University of Illinois at Urbana-Champaign, USA, and Technical Program Committee members Hong-Yeop Song of Yonsei University, Korea, and Kyeongcheol Yang of Pohang University of Science and Technology, Korea.

The 10th Annual ASIACRYPT 2004 was held in Jeju Island, Korea, d- ing December 5-9, 2004. This conference was organized by the International Association for Cryptologic Research (IACR) in cooperation with KIISC (- rean Institute of Information Security and Cryptology) and IRIS (International Research center for Information Security) at ICU (Information and Communi- tionsUniversity),andwas?nanciallysupportedbyMIC(MinistryofInformation and Communication) in Korea. The conference received, from 30 countries, 208 submissions that represent the current state of work in the cryptographic community worldwide, covering all areas of cryptologic research. Each paper, without the authors' information, was reviewed by at least three members of the program committee, and the papers (co-)authored by members of the program committee were reviewed by at least six members. We also blinded the reviewers' names among the reviewers until the ?nal decision, by using pseudonyms. The reviews were then followed by deep discussions on the papers, which greatly contributed to the quality of the ?nal selection. In most cases, extensive comments were sent to the authors. Among 208 submissions, the program committee selected 36 papers. Two submissions were merged into a single paper, yielding the total of 35 papers acceptedforpresentationinthetechnicalprogramoftheconference.Manyhi- quality works could not be accepted because of the competitive nature of the conference and the challenging task of selecting a program. These proceedings contain revised versions of the accepted papers. These revisions have not been checked for correctness, and the authors bear full responsibility for the contents of their papers.

The Cryptographers' Track (CT-RSA) is a research conference within the RSA conference, the largest, regularly staged computer security event. CT-RSA 2004 was the fourth year of the Cryptographers' Track, and it is now an established venue for presenting practical research results related to cryptography and data security. The conference received 77 submissions, and the program committee sel- ted 28 of these for presentation. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to cryp- graphy. Each paper was reviewed by at least three program committee members. Extended abstracts of the revised versions of these papers are in these proc- dings. The program also included two invited lectures by Dan Boneh and Silvio Micali. I am extremely grateful to the program committee members for their en- mous investment of time and e?ort in the di?cult and delicate process of review and selection. Many of them attended the program committee meeting during the Crypto 2003 conference at the University of California, Santa Barbara.

The mid-1990ssaw an exciting convergenceof a number of dieren t information protection technologies, whose theme was the hiding (as opposed to encryption) of information. Copyright marking schemes are about hiding either copyright notices or individual serial numbers imperceptibly in digital audio and video, as a component in intellectual property protection systems; anonymous c- munication is another area of rapid growth, with people designing systems for electronic cash, digital elections, and privacy in mobile communications; se- rity researchers are also interested in 'stray' communication channels, such as those which arise via shared resourcesin operating systems or the physical le- age of information through radio frequency emissions; and n ally, many workers in these elds drew inspiration from 'classical' hidden communication methods such as steganography and spread-spectrum radio. The rst international workshop on this new emergent discipline of inf- mation hiding was organised by Ross Anderson and held at the Isaac Newton Institute, Cambridge, from the 30th May to the 1st June 1996, and was judged by attendees to be a successful and signi cant event. In addition to a number of research papers, we had invited talks from David Kahn on the history of steganography and from Gus Simmons on the history of subliminal channels. We also had a number of discussion sessions, culminating in a series of votes on common terms and de nitions. These papers and talks, together with minutes of the discussion, can be found in the proceedings, which are published in this series as Volume 1174.

The 2003 Information Security Conference was the sixth in a series that started with the InformationSecurity Workshopin 1997.A distinct feature of this series is the wide coverage of topics with the aim of encouraging interaction between researchers in di?erent aspects of information security. This trend continued in the program of this year's conference. There were 133 paper submissions to ISC 2003. From these submissions the 31papersintheseproceedingswereselectedbytheprogramcommittee,covering a wide range of technical areas. These papers are supplemented by two invited papers;athirdinvitedtalkwaspresentedattheconferencebutisnotrepresented by a written paper. We would like to extend our sincere thanks to all the authors that submitted papers to ISC 2003, and we hope that those whose papers were declined will be able to ?nd an alternative forum for their work. We are also very grateful to the three eminent invited speakers at the conference: Paul van Oorschot (Carleton University, Canada), Ueli Maurer (ETH Zur * ich, Switzerland), and Andy Clark (Inforenz Limited, UK). We were fortunate to have an energetic team of experts who took onthe task of the program committee. Their names may be found overleaf, and we thank them warmly for their considerable e?orts. This team was helped by an even larger number of individuals who reviewed papers in their particular areas of expertise. A list of these names is also provided, which we hope is complete.

his book presents the refereed proceedings of the 6th European Symposium on Research in Computer Security, ESORICS 2000, held in Toulouse, France in October 2000.The 19 revised full papers presented were carefully reviewed and selected from a total of 75 submissions. The papers are organized in sections on personal devices and smart cards, electronic commerce protocols, access control, protocol verification, Internet security, security property analysis, and mobile agents.

Since 1998, RAID has established its reputation as the main event in research on intrusion detection, both in Europe and the United States. Every year, RAID gathers researchers, security vendors and security practitioners to listen to the most recent research results in the area as well as experiments and deployment issues. This year, RAID has grown one step further to establish itself as a well-known event in the security community, with the publication of hardcopy proceedings. RAID 2000 received 26 paper submissions from 10 countries and 3 continents. The program committee selected 14 papers for publication and examined 6 of them for presentation. In addition RAID 2000 received 30 extended abstracts proposals; 15 of these extended abstracts were accepted for presentation. - tended abstracts are available on the website of the RAID symposium series, http://www.raid-symposium.org/. We would like to thank the technical p- gram committee for the help we received in reviewing the papers, as well as all the authors for their participation and submissions, even for those rejected. As in previous RAID symposiums, the program alternates between fun- mental research issues, such as newtechnologies for intrusion detection, and more practical issues linked to the deployment and operation of intrusion det- tion systems in a real environment. Five sessions have been devoted to intrusion detection technology, including modeling, data mining and advanced techniques.

The EUROCRYPT '96 conference was sponsored by the International Asso- ation for Cryptologic Research (IACR)l, in cooperation with the University of Saragossa. It took place at the Palacio de Congresos in Saragossa, Spain, during May 12-16, 1996. This was the fifteenth annual EUROCRYPT conference (this name has been used since the third conference held in 1984), each of which has been held in a different city in Europe. For the second time, proceedings were available at the conference. JosC Pastor Franco, the General Chair, was resp- sible for local organization and registration. His contribution to the snccess of the conference is gratefully acknowledged. The Program Committee considered 126 submitted papers and selected 34 for presentation. Each paper was sent to all members of the Program Committee and was assigned to at least three of them for careful evaluation. There were also two invited talks. James L. Massey, this year's IACR Distinguished Ltcturer, gave a lecture entitled "e;The difficulty with difficulty"e;. Massey is the third to receive this honor, the first two being Gustavus Simmons and Adi Shamir. Shafi Goldwasser gave an invited talk entitled "e;Multi party secure protocols: past and present"e;. These proceedings contain revised versions of the 34 contributed talks. While the papers were carefully selected, they have not been refereed like submissions to a refereed journal. The authors bear full responsibility for the contents of their papers. Some authors may write final versions of their papers for publication in a refereed journal.
