Money is changing and this may mean a new world order. David Birch sets out the economic and technological imperatives concerning digital money, and discusses its potential impact. Tensions will inevitably arise: between old and new, between public and private, and, most importantly, between East and West. This book contributes to the debate that we must have to shape the International Monetary and Financial System of the near future.

Orte ... Eine einsame Bar in Tokyo und Lärm ... ein luxuriöses Hotelzimmer in Paris und Gefühle ... ein nächtlicher Bahnhof in Russland und Spuren ... ein psychiatrisches Gefängnis in den U.S.A und Täuschungen ... dazu Schatten, die flackern, die zu Zeichen werden und Menschen in Atem halten ... einen verliebten saudischen Prinzen ... eine ambitionierte französische Ermittlerin ... den Sohn eines Mafia-Paten ... einen erfolglosen Selbstmörder ... ein geheimnisvolles Geschwisterpaar ... bis aus dem Flackern ein Tanzen wird, fast eine Kunst, die sich verschwendet und alles ändert ...

Auszug: Die zyklische Redundanzpr fung (engl. cyclic redundancy check, daher meist CRC) ist ein Verfahren zur Bestimmung eines Pr fwerts f r Daten, um Fehler bei der bertragung oder Speicherung erkennen zu k nnen. F r jeden Datenblock wird nach einem bestimmten Verfahren ein sogenannter CRC-Wert berechnet, der dem Datenblock angef gt wird. Zur berpr fung der Daten wird dasselbe Berechnungsverfahren auf den Datenblock einschlie lich des angef gten CRC-Werts angewandt. Ist das Ergebnis dann Null, kann angenommen werden, dass der Datenblock unverf lscht ist. Verschiedene technische Anwendungen weichen allerdings von diesem Schema ab, indem sie beispielsweise die Berechnung mit einem bestimmten Wert initialisieren oder den CRC-Wert vor der bermittlung invertieren. CRC ist so ausgelegt, dass Fehler bei der bertragung der Daten, wie sie beispielsweise durch Rauschen auf der Leitung verursacht werden k nnten, mit hoher Wahrscheinlichkeit entdeckt werden. CRCs von seriellen Daten bertragungen k nnen sehr einfach in Hardware realisiert werden. Zum Beispiel werden Daten bertragungen ber Ethernet, sowie die meisten Festplatten- bertragungen mit CRC-Verfahren gepr ft. Das CRC-Verfahren ist nur f r di...

The Manga Guide to Cryptography breaks down how ciphers work, what makes them secure or insecure, and how to decode them. Comic illustrations make it easy to learn about classic substitution, polyalphabetic, and transposition ciphers; symmetric-key algorithms like block and DES (Data Encryption Standard) ciphers; how to use public key encryption technology to generate public/private keys and cryptograms; practical applications of encryption such as digital signatures, identity fraud countermeasures, and 'man in the middle' attack countermeasures.

Hash functions are the cryptographer’s Swiss Army knife. Even though they play an integral part in today’s cryptography, existing textbooks discuss hash functions only in passing and instead often put an emphasis on other primitives like encryption schemes. In this book the authors take a different approach and place hash functions at the center. The result is not only an introduction to the theory of hash functions and the random oracle model but a comprehensive introduction to modern cryptography. After motivating their unique approach, in the first chapter the authors introduce the concepts from computability theory, probability theory, information theory, complexity theory, and information-theoretic security that are required to understand the book content. In Part I they introduce the foundations of hash functions and modern cryptography. They cover a number of schemes, concepts, and proof techniques, including computational security, one-way functions, pseudorandomness and pseudorandom functions, game-based proofs, message authentication codes, encryption schemes, signature schemes, and collision-resistant (hash) functions. In Part II the authors explain the random oracle model, proof techniques used with random oracles, random oracle constructions, and examples of real-world random oracle schemes. They also address the limitations of random oracles and the random oracle controversy, the fact that uninstantiable schemes exist which are provably secure in the random oracle model but which become insecure with any real-world hash function. Finally in Part III the authors focus on constructions of hash functions. This includes a treatment of iterative hash functions and generic attacks against hash functions, constructions of hash functions based on block ciphers and number-theoretic assumptions, a discussion of privately keyed hash functions including a full security proof for HMAC, and a presentation of real-world hash functions. The text is supported with exercises, notes, references, and pointers to further reading, and it is a suitable textbook for undergraduate and graduate students, and researchers of cryptology and information security.

This is a comprehensive description of the cryptographic hash function BLAKE, one of the five final contenders in the NIST SHA3 competition, and of BLAKE2, an improved version popular among developers. It describes how BLAKE was designed and why BLAKE2 was developed, and it offers guidelines on implementing and using BLAKE, with a focus on software implementation. In the first two chapters, the authors offer a short introduction to cryptographic hashing, the SHA3 competition and BLAKE. They review applications of cryptographic hashing, they describe some basic notions such as security definitions and state-of-the-art collision search methods and they present SHA1, SHA2 and the SHA3 finalists. In the chapters that follow, the authors give a complete description of the four instances BLAKE-256, BLAKE-512, BLAKE-224 and BLAKE-384; they describe applications of BLAKE, including simple hashing with or without a salt and HMAC and PBKDF2 constructions; they review implementation techniques, from portable C and Python to AVR assembly and vectorized code using SIMD CPU instructions; they describe BLAKE’s properties with respect to hardware design for implementation in ASICs or FPGAs; they explain BLAKE's design rationale in detail, from NIST’s requirements to the choice of internal parameters; they summarize the known security properties of BLAKE and describe the best attacks on reduced or modified variants; and they present BLAKE2, the successor of BLAKE, starting with motivations and also covering its performance and security aspects. The book concludes with detailed test vectors, a reference portable C implementation of BLAKE, and a list of third-party software implementations of BLAKE and BLAKE2. The book is oriented towards practice – engineering and craftsmanship – rather than theory. It is suitable for developers, engineers and security professionals engaged with BLAKE and cryptographic hashing in general and for applied cryptography researchers and students who need a consolidated reference and a detailed description of the design process, or guidelines on how to design a cryptographic algorithm.

Hash tables can do a lot more than you might think! Data Management Solutions Using SAS Hash Table Operations: A Business Intelligence Case Study concentrates on solving your challenging data management and analysis problems via the power of the SAS hash object, whose environment and tools make it possible to create complete dynamic solutions. To this end, this book provides an in-depth overview of the hash table as an in-memory database with the CRUD (Create, Retrieve, Update, Delete) cycle rendered by the hash object tools. By using this concept and focusing on real-world problems exemplified by sports data sets and statistics, this book seeks to help you take advantage of the hash object productively, in particular, but not limited to, the following tasks: select proper hash tools to perform hash table operations use proper hash table operations to support specific data management tasks use the dynamic, run-time nature of hash object programming understand the algorithmic principles behind hash table data look-up, retrieval, and aggregation learn how to perform data aggregation, for which the hash object is exceptionally well suited manage the hash table memory footprint, especially when processing big data use hash object techniques for other data processing tasks, such as filtering, combining, splitting, sorting, and unduplicating. Using this book, you will be able to answer your toughest questions quickly and in the most efficient way possible!

In a small town where an epidemic of tuberculosis rages, Robert Maser, a travelling garment salesman arrives and persuades the local schoolteacher, Lars, to join him on a bizarre quest to find the world's best Swedish hash. Together they wander the Swedish countryside to sample the variety of humble family recipes.
