Reconfigurable RF-frontends aim to cope with the continuous pursuit of wider frequency coverage, higher efficiency, further compactness and lower cost of ownership. They are expected to lay the foundations of future software defined or cognitive radios. As a potential enabling technology for the frontends, the tunable ferroelectric devices have shown not only enhanced performance but also new functionalities. This book explores the recent developments in the field. It provides a cross-sectional perspective on the interdisciplinary research. With attention to the devices based on ceramic thick-films and crystal thin-films, the book reviews the adapted technologies of material synthesis, film deposition and multilayer circuitry. Next, it highlights the original classes of thin-film ferroelectric devices, including stratified metal-insulator-metal varactors with suppression of acoustic resonance and programmable bi-stable high frequency capacitors. At the end the book analyzes how the frontends can be reformed by tunable multiband antennas, tunable single- and multiband impedance matching networks and tunable substrate integrated waveguide filters, which are all built on low cost ferroelectric thick-films. For all the above devices, the theoretical analyses, modeling and design methods are elaborated, while through demonstrative prototypes the application potential is evaluated.

The 2004 Information Security Conference was the seventh in a series that started with the Information Security Workshop in 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 c- tinuedintheprogramofthisyear sconference.Theprogramcommitteereceived 106 submissions, from which 36 were selected for presentation. Each submission was reviewed by at least three experts in the relevant research area. We would liketothankalltheauthorsfortakingtheirtimetopreparethesubmissions, and wehopethatthosewhosepapersweredeclinedwillbeableto?ndanalternative forum for their work. We were fortunate to have an energetic team of experts who took on the task of the program committee. Their names may be found overleaf, and we thank them warmly for their time and e?orts. This team was helped by an even larger number of external reviewers who reviewed papers in their particular areas of expertise. A list of these names is also provided, which we hope is complete. We would also like to thank the advisory committee for their advice and s- port.TheexcellentlocalarrangementswerehandledbyDirkBalfanzandJessica Staddon. We made use of the electronic submission and reviewing software s- plied by COSIC at the Katholieke Universiteit Leuven. Both the software and the ISC 2004 website were run on a server at UNC Charlotte, and were perfectly maintained by Seung-Hyun Im. We also appreciate assistance from Lawrence Teo in editing the proceedings."

This book constitutes the refereed proceedings of the 8th International Conference on the Theory and Application of Cryptology and Information Security, ASIACRYPT 2002, held in Singapore, in December 2002.The 34 revised full papers presented together with two invited contributions were carefully reviewed and selected from 173 submissions on the basis of 875 review reports. The papers are organized in topical sections on public key cryptography, authentication, theory, block ciphers, distributed cryptography, cryptanalysis, public key cryptanalysis, secret sharing, digital signatures, applications, Boolean functions, key management, and ID-based cryptography.

ThePKC2000conferencewasheldattheMelbourneExhibitionCentre, Victoria, Australia, January 18-20, 2000. It was the third conference in the international workshop series dedicated to practice and theory in public key cryptography. The program committee of the conference received 70 full submissions from around the world, of which 31 were selected for presentation. All submissions were reviewed by experts in the relevant areas. The program committee consisted of 19 experts in cryptography and data se- rity drawn from the international research community, these being Chin-Chen Chang (National Chung Cheng University, Taiwan), Claude Cr epeau (McGill University, Canada), Ed Dawson (Queensland University of Technology, A- tralia), Yvo Desmedt (Florida State University, USA), Hideki Imai (Co-chair, UniversityofTokyo, Japan), MarkusJakobsson(BellLabs, USA), KwangjoKim (Information and Communications University, Korea), Arjen Lenstra (Citibank, USA), TsutomuMatsumoto(YokohamaNationalUniversity, Japan), DavidN- cache (Gemplus, France), Eiji Okamoto (University of Wisconsin-Milwaukee, USA), TatsuakiOkamoto(NTTLabs, Japan), JosefPieprzyk(UniversityofW- longong, Australia), Jean-Jacques Quisquater (Universit e Catholique de L- vain, Belgium), Nigel Smart (HP Labs Bristol, UK), Vijay Varadharajan (U- versity of Western Sydney, Australia), Serge Vaudenay (Ecole Polytechnique F ed erale de Lausanne, Switzerland), Moti Yung (CertCo, USA), and Yuliang Zheng (Co-chair, Monash University, Australia). Members of the committee spent numerous hours in reviewing the submissions and providing advice and comments on the selection of paper

This book constitutes the refereed proceedings of the Second International Workshop on Practice and Theory in Public Key Cryptography, PKC'99, held in Kamakura, Japan in March 1999. The 25 revised full papers presented were carefully reviewed and selected from a total of 61 submissions. The volume reports most recent research results on all relevant aspects in public key cryptography. Among the topics covered are digital signatures, anonymous finger printing, message authentication, digital payment, key escrow, RSA systems, hash functions, decision oracles, random numbers, finite field computations, pay-per-view-systems, and electronic commerce.

This book constitutes the refereed proceedings of the First International Workshop on Practice and Theory in Public Key Cryptography, PKC'98, held in Pacifico Yokohama, Japan, in February 1998.
The volume presents four invited contributions together with 18 revised full papers selected from 30 submissions. The papers address all current issues in research and design in the area including digital signature schemes, digital payment systems, electronic commerce, cryptographic protocols, as well as foundational issues like integer factorization, elliptic curve aspects, hash functions, finite fields, etc.

This book contains the proceedings of AUSCRYPT '92, an international conference on cryptologic research held on the Gold Coast, Australia, in December 1992. This is the third conference held outside the series of CRYPTO meetings held in Santa Barbara, California, each August and EUROCRYPT meetings held in European countries each northern spring. The first two were AUSCRYPT '90, held in Australia, and ASIACRYPT '91, held in Japan. The volume contains three invited papers and 44 contributed papers selected from 77 submissions. The articles cover all main topics in modern computer and communications security research.These include: - authentication - secret sharing - digital signatures - one-way hashing functions - design of block ciphers - cryptanalysis - cryptographic protocols - pseudo-random sequences and functions - public key cryptography.
