This book constitutes the refereed proceedings of the 5th International Conference on Information Theoretic Security, held in Amsterdam, The Netherlands, in May 2011.
The 12 revised full papers presented together with 7 invited lectures were carefully reviewed and selected from 27 submissions. Understanding the minimal requirements for information-theoretic security is a central part of this line of research. Very attractive is the mathematical neatness of the field, and its rich connections to other areas of mathematics, like probability and information theory, algebra, combinatorics, coding theory, and quantum information processing, just to mention the most prominent ones.

Since the advent of optical communications, a greattechnological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Sta- ing from a few Mb/s single channel systems, a fast and constant technological development has led to the actual 10 Gb/s per channel dense wavelength - vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers. Nevertheless, despite such a pace in technological progress, optical c- munications are still in a primitive stage if compared, for instance, to radio communications: the widely spread on-off keying (OOK) modulation format is equivalent to the rough amplitude modulation (AM) format, whereas the DWDM technique is nothing more than the optical version of the frequency - vision multiplexing (FDM) technique. Moreover, adaptive equalization, ch- nel coding or maximum likelihood detection are still considered something "exotic" in the optical world. This is mainly due to the favourable char- teristics of the fiber optic channel (large bandwidth, low attenuation, channel stability, ...), which so far allowed us to use very simple transmission and detection techniques.

Nowadays it is hard to find an electronic device which does not use codes: for example, we listen to music via heavily encoded audio CD's and we watch movies via encoded DVD's. There is at least one area where the use of encoding/decoding is not so developed, yet: Flash non-volatile memories. Flash memory high-density, low power, cost effectiveness, and scalable design make it an ideal choice to fuel the explosion of multimedia products, like USB keys, MP3 players, digital cameras and solid-state disk.

In ECC for Non-Volatile Memories the authors expose the basics of coding theory needed to understand the application to memories, as well as the relevant design topics, with reference to both NOR and NAND Flash architectures. A collection of software routines is also included for better understanding.

The authors form a research group (now at Qimonda) which is the typical example of a fruitful collaboration between mathematicians and engineers.

This multi-authored textbook addresses graduate students with a background in physics, mathematics or computer science. No research experience is necessary. Consequently, rather than comprehensively reviewing the vast body of knowledge and literature gathered in the past twenty years, this book concentrates on a number of carefully selected aspects of quantum information theory and technology. Given the highly interdisciplinary nature of the subject, the multi-authored approach brings together different points of view from various renowned experts, providing a coherent picture of the subject matter. The book consists of ten chapters and includes examples, problems, and exercises. The first five present the mathematical tools required for a full comprehension of various aspects of quantum mechanics, classical information, and coding theory. Chapter 6 deals with the manipulation and transmission of information in the quantum realm. Chapters 7 and 8 discuss experimental implementations of quantum information ideas using photons and atoms. Finally, chapters 9 and 10 address ground-breaking applications in cryptography and computation.

The topics dealt with are algorithms and data structures, applications, combinatorial enumeration, combinatorial optimization, complexity theory, computational biology, databases, decompositions and combinatorial designs, discrete and computational geometry, including graph drawing, and graph theory and combinatorics.

As future generation information technology (FGIT) becomes specialized and fr- mented, it is easy to lose sight that many topics in FGIT have common threads and, because of this, advances in one discipline may be transmitted to others. Presentation of recent results obtained in different disciplines encourages this interchange for the advancement of FGIT as a whole. Of particular interest are hybrid solutions that c- bine ideas taken from multiple disciplines in order to achieve something more signi- cant than the sum of the individual parts. Through such hybrid philosophy, a new principle can be discovered, which has the propensity to propagate throughout mul- faceted disciplines. FGIT 2009 was the first mega-conference that attempted to follow the above idea of hybridization in FGIT in a form of multiple events related to particular disciplines of IT, conducted by separate scientific committees, but coordinated in order to expose the most important contributions. It included the following international conferences: Advanced Software Engineering and Its Applications (ASEA), Bio-Science and Bio-Technology (BSBT), Control and Automation (CA), Database Theory and Application (DTA), D- aster Recovery and Business Continuity (DRBC; published independently), Future G- eration Communication and Networking (FGCN) that was combined with Advanced Communication and Networking (ACN), Grid and Distributed Computing (GDC), M- timedia, Computer Graphics and Broadcasting (MulGraB), Security Technology (SecTech), Signal Processing, Image Processing and Pattern Recognition (SIP), and- and e-Service, Science and Technology (UNESST).

In 1974, the British government admitted that its WWII secret intelligence organization had read Germany's ciphers on a massive scale. The intelligence from these decrypts influenced the Atlantic, the Eastern Front and Normandy. Why did the Germans never realize the Allies had so thoroughly penetrated their communications? As German intelligence experts conducted numerous internal investigations that all certified their ciphers' security, the Allies continued to break more ciphers and plugged their own communication leaks. How were the Allies able to so thoroughly exploit Germany's secret messages? How did they keep their tremendous success a secret? What flaws in Germany's organization allowed this counterintelligence failure and how can today's organizations learn to avoid similar disasters? This book, the first comparative study of WWII SIGINT (Signals Intelligence), analyzes the characteristics that allowed the Allies SIGINT success and that fostered the German blindness to Enigma's compromise.

Biometrics is a rapidly evolving field with applications ranging from accessing one 's computer to gaining entry into a country. The deployment of large-scale biometric systems in both commercial and government applications has increased public awareness of this technology. Recent years have seen significant growth in biometric research resulting in the development of innovative sensors, new algorithms, enhanced test methodologies and novel applications. This book addresses this void by inviting some of the prominent researchers in Biometrics to contribute chapters describing the fundamentals as well as the latest innovations in their respective areas of expertise.

Privacy, Security and Trust within the Context of Pervasive Computing is an edited volume based on a post workshop at the second international conference on Pervasive Computing. The workshop was held April18-23, 2004, in Vienna, Austria.

The goal of the workshop was not to focus on specific, even novel mechanisms, but rather on the interfaces between mechanisms in different technical and social problem spaces. An investigation of the interfaces between the notions of context, privacy, security, and trust will result in a deeper understanding of the "atomic" problems, leading to a more complete understanding of the social and technical issues in pervasive computing.

The NordSec workshops were started in 1996 with the aim of bringing together - searchers and practitioners within computer security in the Nordic countries - thereby establishing a forum for discussions and co-operation between universities, industry and computer societies. Since then, the workshop has developed into a fully fledged inter- tional information security conference, held in the Nordic countries on a round robin basis. The 14th Nordic Conference on Secure IT Systems was held in Oslo on 14-16 October 2009. Under the theme Identity and Privacy in the Internet Age, this year's conference explored policies, strategies and technologies for protecting identities and the growing flow of personal information passing through the Internet and mobile n- works under an increasingly serious threat picture. Among the contemporary security issues discussed were security services modeling, Petri nets, attack graphs, electronic voting schemes, anonymous payment schemes, mobile ID-protocols, SIM cards, n- work embedded systems, trust, wireless sensor networks, privacy, privacy disclosure regulations, financial cryptography, PIN verification, temporal access control, random number generators, and some more. As a pre-cursor to the conference proper, the Nordic Security Day on Wednesday 14 October hosted talks by leading representatives from industry, academia and the g- ernment sector, and a press conference was given.

In recent years there has been growing scientific interest in the triangular relationship between knowledge. complexity and innovation systems. The concept of'innovation systems' carries the idea that innovations do not originate as isolated discrete phenomena, but are generated through the interaction of a number of actors or agents. This set of actors and interactions possess certain specific characteristics that tend to remain over time. Such characteristics are also shared by national, regional, sectoral and technological interaction systems. They can all be represented as sets of institutional] actors and interactions, whose ultimate goal is the production and diffusion of knowledge. The major theoretical and policy problem posed by these systems is that knowledge is generated not only by individuals and organisations, but also by the often complex pattern of interaction between them. To understand how organisations create new products, new production techniques and new organisational forms is important. An even more fundamental need is to understand how organisations create new knowledge if this knowledge creation lies in the mobilisation and conversion of tacit knowledge. Although much has been written about the importance of knowledge in management, little attention has been paid to how knowledge is created and how the knowledge creation process is managed. The third component of the research triangle concerns complexity."

FastSoftwareEncryption2009wasthe16thin a seriesofworkshopsonsymm- ric key cryptography. Starting from 2002, it is sponsored by the International Association for Cryptologic Research (IACR). FSE 2009 was held in Leuven, Belgium, after previous venues held in Cambridge, UK (1993, 1996), Leuven, Belgium (1994, 2002), Haifa, Israel (1997), Paris, France (1998, 2005), Rome, Italy (1999), New York, USA (2000), Yokohama, Japan (2001), Lund, Sweden (2003), New Delhi, India (2004), Graz, Austria (2006), Luxembourg, Lux- bourg (2007), and Lausanne, Switzerland (2008). The workshop's main topic is symmetric key cryptography, including the designoffast andsecuresymmetrickeyprimitives,suchas block ciphers,stream ciphers, hash functions, message authentication codes, modes of operation and iteration, as well as the theoretical foundations of these primitives. This year, 76 papers were submitted to FSE including a large portion of papers on hash functions, following the NIST SHA-3 competition, whose wo- shop was held just after FSE in the same location. From the 76 papers, 24 were accepted for presentation. It is my pleasure to thank all the authors of all s- missions for the high-quality research, which is the base for the scienti?c value of the workshop. The review process was thorough (each submission received the attention of at least three reviewers), and at the end, besides the accepted papers, the Committee decided that the merits of the paper "Blockcipher-Based Hashing Revisited" entitled the authors to receive the best paper award. I wish to thank all Committee members and the referees for their hard and dedicated work.
