Coding theory and cryptology Books

Book SynopsisThe Science of Secrecy from Ancient Egypt to Quantum Cryptography From the best-selling author of Fermat’s Last Theorem, The Code Book is a history of man’s urge to uncover the secrets of codes, from Egyptian puzzles to modern day computer encryptions. As in Fermat’s Last Theorem, Simon Singh brings life to an anstonishing story of puzzles, codes, languages and riddles that reveals man’s continual pursuit to disguise and uncover, and to work out the secret languages of others. Codes have influenced events throughout history, both in the stories of those who make them and those who break them. The betrayal of Mary Queen of Scots and the cracking of the enigma code that helped the Allies in World War II are major episodes in a continuing history of cryptography. In addition to stories of intrigue and warfare, Simon Singh also investigates other codes, the unravelling of genes and the rediscovery of ancient languages and most tantalisingly, the Beale ciphers, an unbroken code that could hold the key to a $20 million treasure.Trade Review‘A fascinating meander through the centuries; replete with tales of intrigue, political chicanery, military secrecy and academic rivalry.’The Times

Book SynopsisTrade ReviewAn important new book…[It] attempts to do for blockchain what the likes of Lawrence Lessig and Tim Wu did for the Internet and cyberspace—explain how a new technology will upend the current legal and social order…A fine, deeply-researched book that can be expected to show up on law school syllabi for years to come…Blockchain and the Law is not just a theoretical guide. It’s also a moral one. -- Jeff John Roberts * Fortune *Blockchain and the Law perfectly links technical understanding with practical and legal implications. Blockchains will matter crucially; this book, beautifully and clearly written for a wide audience, powerfully demonstrates how. -- Lawrence Lessig, Harvard Law SchoolUseful to an educated readership…If you…don’t ‘get’ crypto, this is the book-length treatment for you. It sees merit and potential in crypto, without buying into any particular claim just for the sake of hype. -- Tyler Cowen * Marginal Revolution *De Filippi and Wright stress that because blockchain is essentially autonomous, it is inflexible, which leaves it vulnerable, once it has been set in motion, to the sort of unforeseen consequences that laws and regulations are best able to address. -- James Ryerson * New York Times Book Review *De Filippi and Wright offer neither a jeremiad nor a gospel; unlike the breathlessness that pervades much writing on blockchain technology, they stick to sensibleness and sobriety. -- Nathan Schneider * America *Explores the implications of the technology in its broadest sense, positioning it in context of the evolution of the internet, and the development of artificial intelligence and autonomous systems which are continually touching more areas of our daily lives…A fascinating and comprehensive read that poses many questions we should debate and settle before blockchain technology becomes ubiquitous. * Breaker *At long last—a deeply researched, thoughtful, and measured analysis of blockchain technology and the policies that could help us harvest its opportunities and avoid its pitfalls. Blockchain and the Law should be required reading for anyone serious about understanding this major emerging element of our technological ecosystem. -- Yochai Benkler, author of The Wealth of NetworksA well-written and comprehensive book that cuts through the blockchain hype. It not only highlights the powers and limitations of blockchain technology, but solidly grounds it in a larger social and legal context. -- Bruce Schneier, author of Data and GoliathIf you are looking to understand the intricacies of the relationship between the law and blockchain technology, then this book should be on your list…[It] makes it clear that regulators must redefine their approach because restrictive regulations will stifle the growth of the industry. -- Alexander Lielacher * BTCManager *

Book SynopsisAn investigation into the lost treasures of Jesse James and the Freemasons and their connections to the Templars, Rosicrucians, and the Founding Fathers Jesse James left behind secret diaries and coded treasure maps. Working to decrypt these maps, Daniel J. Duke--the great-great grandson of Jesse James--reveals hidden treasures yet to be recovered as well as connections between the infamous train robber and Freemasonry, the Knights Templar, the Founding Fathers, and Jewish mysticism. The author explains how Jesse James faked his death and lived out his final years under the name James L. Courtney. He uncovers James’ affiliation with the Knights of the Golden Circle, a secret society that buried Confederate gold across the United States, and shows how the hidden treasures coded into James’ maps were not affiliated with the KGC but with the Freemasons, the Knights Templar, and the treasure of the Temple Mount. Using sacred geometry, gematria, and the Kabbalistic Tree of Life symbol, the author explains the encoded map technique used by the Freemasons to hide and later recover treasures, an esoteric template known as the “Veil”. He shows how the Veil template confirms the locations of Jesse James’ recovered treasures in Texas as well as other suspected treasure locations, such as the Oak Island Money Pit and Victorio Peak in New Mexico. Tracing knowledge of the Veil template back through the centuries, the author reveals the Veil hidden on the cover of a 16th-century book that contains a secret map of the New World and the “hooked X” symbol of the Knights Templar. He shows how the template was used not only to hide treasures but also sacred knowledge and relics, such as within the Bruton Vault, which originally contained secrets tied to Francis Bacon, the Freemasons, the Rosicrucians, and the founding of the United States. Applying the Veil template alongside the esoteric secrets of Poussin’s famous painting, Et In Arcadia Ego, and Cassini’s Celestial Globe, Duke shows how the template reveals other Templar and Freemason treasure sites scattered throughout America and around the world.Trade Review“Daniel J. Duke has successfully cracked open part of the mystery surrounding Templar treasure from Jerusalem that had been moved to the Americas to help establish a free nation. Jesse James and the Lost Templar Treasure goes beyond just theorizing that treasure was moved to the Americas and in fact demonstrates the connections and methods utilized to hide certain treasures. There have always been those who have sought to shape history to ensure that freedoms and artifacts could be preserved in the Americas. Daniel J. Duke’s book is on the cutting edge of revealing some of what has remained hidden. Anybody who is interested in the Templar legacy and their connection with the Americas will find true gems in this book!” * Timothy W. Hogan, Templar Grand Master, author, and lecturer *“Having inadvertently fallen down one of the many hidden wells of esoteric knowledge dotted across the North American landscape, author Daniel J. Duke--the great-great-grandson of the outlaw Jesse James--weaves a wonderful tale of Southern intrigue and mysterious treasure. His familial connection enables him to explore the ancient mysteries within the Tree of Life and Veil templates and their connections over time to the Freemasons, the Knights Templar, the Knights of the Golden Circle, Francis Bacon and the Rosicrucians, and Sovereign Grand Commander Albert Pike. Where he travels next on his personal journey of discovery will be the key.” * William F. Mann, author of The Knights Templar in the New World, The Templar Meridians, and Templar *"Duke fulfilled this objective all the way to 5-stars. If you love history, mysteries, treasure hunting and of course Jesse James, do not hesitate to give your full attention to Jesse James and the Lost Templar Treasure." * Kris Helt, Whiskey & Wit Book Review *"Jesse James and the Lost Templar Treasure is an interesting read full of facts about history. The reader will learn more concerning Jesse James and the groups to which he belonged. It is evident that Duke put a lot of time and research into this book. I recommend this book for the history buff and for those with a love for treasure stories and conspiracy theories." * Rachel Dehning, Seattle Book Review *Table of ContentsINTRODUCTION The Hunt for Truth and Treasure ONE Knights, Outlaws, and Treasure Maps TWO Seven Cities of Gold THREE Bruton Parish Church-- America’s Rosslyn Chapel?FOUR Connecting the Dots FIVESignatures in Numbers SIX The Three Veils SEVEN Gates of Light EIGHT Line of Succession NINE Arcadian Shepherds TEN Into the Shadows ELEVEN The Stone of Foundation TWELVELooking behind the Veil THIRTEEN Re-veiling the Maps Notes Bibliography Index

Book SynopsisProofs play a central role in advanced mathematics and theoretical computer science, yet many students struggle the first time they take a course in which proofs play a significant role. This bestselling text''s third edition helps students transition from solving problems to proving theorems by teaching them the techniques needed to read and write proofs. Featuring over 150 new exercises and a new chapter on number theory, this new edition introduces students to the world of advanced mathematics through the mastery of proofs. The book begins with the basic concepts of logic and set theory to familiarize students with the language of mathematics and how it is interpreted. These concepts are used as the basis for an analysis of techniques that can be used to build up complex proofs step by step, using detailed ''scratch work'' sections to expose the machinery of proofs about numbers, sets, relations, and functions. Assuming no background beyond standard high school mathematics, this booTrade Review'Not only does this book help students learn how to prove results, it highlights why we care so much. It starts in the introduction with some simple conjectures and gathering data, quickly disproving the first but amassing support for the second. Will that pattern persist? How can these observations lead us to a proof? The book is engagingly written, and covers - in clear and great detail - many proof techniques. There is a wealth of good exercises at various levels. I've taught problem solving before (at The Ohio State University and Williams College), and this book has been a great addition to the resources I recommend to my students.' Steven J. Miller, Williams College, Massachusetts'This book is my go-to resource for students struggling with how to write mathematical proofs. Beyond its plentiful examples, Velleman clearly lays out the techniques and principles so often glossed over in other texts.' Rafael Frongillo, University of Colorado, Boulder'I've been using this book religiously for the last eight years. It builds a strong foundation in proof writing and creates the axiomatic framework for future higher-level mathematics courses. Even when teaching more advanced courses, I recommend students to read chapter 3 (Proofs) since it is, in my opinion, the best written exposition of proof writing techniques and strategies. This third edition brings a new chapter (Number Theory), which gives the instructor a few more topics to choose from when teaching a fundamental course in mathematics. I will keep using it and recommending it to everyone, professors and students alike.' Mihai Bailesteanu, Central Connecticut State University'Professor Velleman sets himself the difficult task of bridging the gap between algorithmic and proof-based mathematics. By focusing on the basic ideas, he succeeded admirably. Many similar books are available, but none are more treasured by beginning students. In the Third Edition, the constant pursuit of excellence is further reinforced.' Taje Ramsamujh, Florida International University'Proofs are central to mathematical development. They are the tools used by mathematicians to establish and communicate their results. The developing mathematician often learns what constitutes a proof and how to present it by osmosis. How to Prove It aims at changing that. It offers a systematic introduction to the development, structuring, and presentation of logical mathematical arguments, i.e. proofs. The approach is based on the language of first-order logic and supported by proof techniques in the style of natural deduction. The art of proving is exercised with naive set theory and elementary number theory throughout the book. As such, it will prove invaluable to first-year undergraduate students in mathematics and computer science.' Marcelo Fiore, University of Cambridge'Overall, this is an engagingly-written and effective book for illuminating thinking about and building a careful foundation in proof techniques. I could see it working in an introduction to proof course or a course introducing discrete mathematics topics alongside proof techniques. As a self-study guide, I could see it working as it so well engages the reader, depending on how able they are to navigate the cultural context in some examples.' Peter Rowlett, LMS Newsletter'Altogether this is an ambitious and largely very successful introduction to the writing of good proofs, laced with many good examples and exercises, and with a pleasantly informal style to make the material attractive and less daunting than the length of the book might suggest. I particularly liked the many discussions of fallacious or incomplete proofs, and the associated challenges to readers to untangle the errors in proofs and to decide for themselves whether a result is true.'

Book SynopsisToday, Alan Turing is a well-recognised name, but it was not always so. Until the last few years of the 20th century hardly anyone had heard of him or his achievements. All that changed when the British government permitted the story of Bletchley Park during the Second World War to emerge.We learnt that Alan Turing had had a pivotal role in breaking the Enigma cipher, used by German forces.This was so significant that it helped to shorten the length of the war. Alan Turing was an extraordinary man who crammed into a life of only 42 years other careers besides secret codebreaker: he was also a mathematician, computer scientist and biologist. For example, with Tommy Flowers he built the first computer. A man ahead of his time, many of his theories and calculations are still relevant today. In this guide to a truly remarkable life, recent research by Alan Turing's nephew, Dermot, has unearthed a fresh perspective and made entirely accessible this story to the modern reader.

Book SynopsisWhy bibliometrics is useful for understanding the global dynamics of science but generate perverse effects when applied inappropriately in research evaluation and university rankings.The research evaluation market is booming. “Ranking,” “metrics,” “h-index,” and “impact factors” are reigning buzzwords. Government and research administrators want to evaluate everything—teachers, professors, training programs, universities—using quantitative indicators. Among the tools used to measure “research excellence,” bibliometrics—aggregate data on publications and citations—has become dominant. Bibliometrics is hailed as an “objective” measure of research quality, a quantitative measure more useful than “subjective” and intuitive evaluation methods such as peer review that have been used since scientific papers were first published in the seventeenth century. In this book,

Book SynopsisAn exploration of infographics and data visualization as a cultural phenomenon, from eighteenth-century print culture to today's data journalism.Infographics and data visualization are ubiquitous in our everyday media diet, particularly in news—in print newspapers, on television news, and online. It has been argued that infographics are changing what it means to be literate in the twenty-first century—and even that they harmonize uniquely with human cognition. In this first serious exploration of the subject, Murray Dick traces the cultural evolution of the infographic, examining its use in news—and resistance to its use—from eighteenth-century print culture to today's data journalism. He identifies six historical phases of infographics in popular culture: the proto-infographic, the classical, the improving, the commercial, the ideological, and the professional.Dick describes the emergence of infographic forms within a wider history of journalis

Book SynopsisThe first edition of Exercises in Programming Style was honored as an ACM Notable Book and praised as The best programming book of the decade. This new edition retains the same presentation but has been upgraded to Python 3, and there is a new section on neural network styles.Using a simple computational task (term frequency) to illustrate different programming styles, Exercises in Programming Style helps readers understand the various ways of writing programs and designing systems. It is designed to be used in conjunction with code provided on an online repository. The book complements and explains the raw code in a way that is accessible to anyone who regularly practices the art of programming. The book can also be used in advanced programming courses in computer science and software engineering programs.The book contains 40 different styles for writing the term frequency task. The styles are grouped into ten categories: historical, basic, function composition, objects and object interactions, reflection and metaprogramming, adversity, data-centric, concurrency, interactivity, and neural networks. The author states the constraints in each style and explains the example programs. Each chapter first presents the constraints of the style, next shows an example program, and then gives a detailed explanation of the code. Most chapters also have sections focusing on the use of the style in systems design as well as sections describing the historical context in which the programming style emerged.Table of ContentsPart 1 HistoricalPart 2 Basic StylesPart 3 Function CompositionPart 4 Objects and Object InteractionPart 5 Reflection and MetaprogrammingPart 6 AdversityPart 7 Data-CentricPart 8 ConcurrencyPart 9 InteractivityPart 10 Neural Networks

Book SynopsisIn 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?

Book SynopsisA mathematical tour of some of the greatest unsolved ciphers of all time In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists

Book SynopsisSignals Intelligence, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War. In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty's famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through or

Book SynopsisAlthough cryptography plays an essential part in most modern solutions, especially in payments, cryptographic algorithms remain a black box for most users of these tools. Just as a sane backend developer does not drill down into low-level disk access details of a server filesystem, payments professionals have enough things to worry about before they ever need to bother themselves with debugging an encrypted value or a message digest. However, at a certain point, an engineer faces the need to identify a problem with a particular algorithm or, perhaps, to create a testing tool that would simulate a counterpart in a protocol that involves encryption.The world of cryptography has moved on with giant leaps. Available technical standards mention acronyms and link to more standards, some of which are very large while others are not available for free. After finding the standards for the algorithm, the specific mode of operation must also be identified. Most implementations use severTable of Contents1. Building Blocks 2. Understanding Payments 3.

Book SynopsisIndependent directors of corporate boards understand the importance of cyber security as a business issue. Increased regulatory requirements, the onslaught of breaches, as well as the replacement of the corporate network perimeter with more third-party partnerships have all contributed to cyber security rising to the top of enterprise risks. Yet, many directors only receive a few brief cyber security updates during the year. Moreover, many directors have devoted their careers to other important business disciplines and may not fully grasp the technical concepts of cyber security.The challenge is that many publications on board cyber security governance address the topic at such a high level that it removes the important context of the cyber security detailsor covers the topic too deeply with hard-to-understand technical language.
