Book SynopsisNot so if the book has been translated into Arabic. Now the reader can discern no meaning in the letters. The text conveys almost no information to the reader, yet the linguistic informa­ tion contained by the book is virtually the same as in the English original. The reader, familiar with books will still recognise two things, however: First, that the book is a book. Second, that the squiggles on the page represent a pattern of abstractions which probably makes sense to someone who understands the mean­ ing of those squiggles. Therefore, the book as such, will still have some meaning for the English reader, even if the content of the text has none. Let us go to a more extreme case. Not a book, but a stone, or a rock with engravings in an ancient language no longer under­ stood by anyone alive. Does such a stone not contain human information even if it is not decipherable? Suppose at some point in the future, basic knowledge about linguistics and clever computer aids allow us to decipher it? Or suppose someone discovers the equivalent of a Rosetta stone which allows us to translate it into a known language, and then into English? Can one really say that the stone contained no information prior to translation? It is possible to argue that the stone, prior to deciphering contained only latent information.Table of ContentsPrologue.- The Author’s Dilemma.- 1 Information: Abstraction or Reality?.- Can Information Exist Outside the Human Brain?.- Can Information be Processed Outside the Human Brain?.- Forms of Human Information and its Communication.- Biological Information Systems.- Inorganic Information Systems.- Non-human Information Processing.- Some Epistemological Considerations.- 2 Information Physics: An Introduction.- The Reality of Information.- The Heart of the Concept.- Information: The Hidden Dimension.- 3 Information and Entropy: The Mathematical Relationship.- Information and Organisation.- The Second Law of Thermodynamics.- The Boltzmann/Schrödinger Equation.- Information as an Inverse Exponential Function of Entropy.- The Constant c.- 4 Measuring the Information Changes of Altered Physical States.- Measuring the Information Content of a Crystal.- Proteins as Information Systems.- The Denaturation of Trypsin.- Concluding Remarks.- 5 Information and Entropy: Further Implications.- Information and Entropy as Viewed by the Communications Engineers.- Positive Entropy.- Negative Entropy.- Information Magnitudes.- The Evolution of the Universe.- 6 Some Further Considerations About the Interrelationship Between Information and Energy.- Pure Energy: Heat, the Antithesis of Information.- The Information Content of Energy.- Motion, Distance and Time.- Information and Potential Energy.- The Interconversion of Energy and Information.- Information Machines.- Structural vs Kinetic Information.- Transformations Between Kinetic and Structural Information.- 7 Information and Work.- The Relationship Between Work and Information.- Energy Transducers.- Work in Biological Systems.- Reassessing the Work Equations.- Measuring the Information Content of Electrical Work.- 8 Summary and Concluding Remarks.- The Basic Propositions.- Historical Perspective.- Why Has Information Been Overlooked?.- The Need for Models and Theories.- The Relevance of Information Physics for a General Theory of Information.- Some Concluding Thoughts.- Appendixes.- A.

Book Synopsis"Number Theory in Science and Communication" is a well-known introduction for non-mathematicians to this fascinating and useful branch of applied mathematics . It stresses intuitive understanding rather than abstract theory and highlights important concepts such as continued fractions, the golden ratio, quadratic residues and Chinese remainders, trapdoor functions, pseudo primes and primitive elements. Their applications to problems in the real world are one of the main themes of the book. This revised fifth edition is augmented by recent advances in coding theory, permutations and derangements and a chapter in quantum cryptography. From reviews of earlier editions – "I continue to find [Schroeder’s] Number Theory a goldmine of valuable information. It is a marvelous book, in touch with the most recent applications of number theory and written with great clarity and humor.’ Philip Morrison (Scientific American) "A light-hearted and readable volume with a wide range of applications to which the author has been a productive contributor – useful mathematics outside the formalities of theorem and proof." Martin GardnerTrade ReviewFrom the reviews of the fifth edition:“Number theory has been a very active field in the last twenty-seven years, and Schroeder’s text has a palimpsest quality, with later mathematical advances layered on earlier ones. … Number Theory in Science and Communication is rewarding to browse, or as a jumping-off point for further research … . It would be a good source of student projects in an undergraduate discrete mathematics or number theory course.” (Ursula Whitcher, The Mathematical Association of America, March, 2011)Table of ContentsA Few Fundamentals.- The Natural Numbers.- Primes.- The Prime Distribution.- Some Simple Applications.- Fractions: Continued, Egyptian and Farey.- Congruences and the Like.- Linear Congruences.- Diophantine Equations.- The Theorems of Fermat Wilson and Euler.- Permutations Cycles and Derangements.- Cryptography and Divisors.- Euler Trap Doors and Public-Key Encryption.- The Divisor Functions.- The Prime Divisor Functions.- Certified Signatures.- Primitive Roots.- Knapsack Encryption.- Residues and Diffraction.- Quadratic Residues.- Chinese and Other Fast Algorithms.- The Chinese Remainder Theorem and Simultaneous Congruences.- Fast Transformation and Kronecker Products.- Quadratic Congruences.- Pseudoprimes, Möbius Transform, and Partitions.- Pseudoprimes Poker and Remote Coin Tossing.- The Möbius Function and the Möbius Transform.- Generating Functions and Partitions.- From Error Correcting Codes to Covering Sets.- Cyclotomy and Polynomials.- Cyclotomic Polynomials.- Linear Systems and Polynomials.- Polynomial Theory.- Galois Fields and More Applications.- Galois Fields.- Spectral Properties of Galois Sequences.- Random Number Generators.- Waveforms and Radiation Patterns.- Number Theory Randomness and “Art”.- Self-Similarity, Fractals and Art.- Self-Similarity, Fractals, Deterministic Chaos and a New State of Matter.

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 SynopsisWe are at the threshold of a new area of the internet that promises to transform the way we engage financially and take the power of data and privacy back from big corporations and give it to the individual through decentralization. This is sometimes called Web 3.0. While Web 1.0 transformed information sharing and commerce and brought us giants like Google and Amazon and Web 2.0 unlocked the social potential of the internet and created Facebook, Twitter, and Snapchat, exactly what will come of Web 3.0 remains to be seen. It is indisputable that the seed of Web 3.0 is the technological, social, and economic innovations that came together in Bitcoin and the blockchain technology it created. But where the first web iterations were relatively straightforward to understand, the inner workings of Web 3.0 remain more opaque and shrouded in mystique. Current voices on Bitcoin and the blockchain revolution fall squarely into one of two camps; either technological experts who are all also invTable of ContentsIntroduction Part 1 - Genealogy of bitcoin technology The technological developments leading to bitcoin. This part is a technological history that reviews the technological developments that Bitcoin builds on. There are a few strands that developed more or less independently that combine into Bitcoin. Once they are explained it is possible to give a deeper explanation of how Bitcoin works. This understanding will inform the remaining parts of the book. Chapter 1: Cryptography The purpose of cryptography is to keep information private by preserving confidentiality, integrity and access to it. Public private key encryption Hashing Zero knowledge proof Chapter 2: Virtual Money In this chapter we will go into the history of electronic or virtual money before bitcoin. Digicash E gold Bitgold b Money Hash cash Chapter 3: Peer-to-peer technology The internet of today is a centralized type of computing working through a number of web servers that function in a hierarchy. Properties of p2p networks Discovering a peer Secure sharing File Sharing from Napster to BitTorrent Chapter 4: Proof of work An inherent problem with the networked world is that accessing and processing information is essentially free, which makes certain types of disruptive behavior easy, which we see in denial of service attacks, spam mail and robocalling. This brings new problems that did not exist when it cost significant money to send a letter, read a paper or book or make a phone call. DDoS Spam Money transactions Chapter 5: Public record Since the time of the code of Hammurabi, the purpose of a public record has been clear: to establish indisputable truth. While this is seemingly the opposite of the privacy and confidentiality entailed by cryptography it serves the purpose of making information shared and immutable. Historical technologies of public record The purpose of public records The accounting revolution and the development of ledgers, double entry bookkeeping to triple entry bookkeeping Chapter 6: Bitcoin From the previous chapters we are now able to piece together how bitcoin and the block chain works. Virtual money - The Bitcoin Encrypting for privacy - The Wallet Public record - The Blockchain Peer to peer network - The Miners Proof of work - Transactions (cryptographic proof and the consensus algorithm) Part 2 - Still searching for Satoshi - who is the historical Satoshi Nakamoto? Much writing about Bitcoin has focused on who the historical person or persons behind Satoshi Nakamoto is. This part will apply a historical critical perspective to this question and sift through the evidence in order to create a better understanding of what we can and cannot say about the identity of Satoshi Nakamoto. Chapter 7: Who dunnit? A review of previous identifications of the person behind Satoshi. This has previously taken the shape of investigative journalism in the style of true crime reporting Joshua Davis, The New Yorker 2011 Adam Penenberg, Fast Company 2011 Alec Liu, Vice 2013 John Markoff, New York Times 2013 Andy Greenberg, Forbes 2014 Leah McGrath Goodman, Newsweek 2014 Skye Grey, blog 2014 Dominic Frisby, Bitcoin the future of money 2014 Nathaniel Popper, New York Time 2015 Andy Greenberg, Gwern Branwen, Wired 2015 Sam Biddle, Gizmodo 2015 Izabella Kasminska, Financial Times 2016 Evan Ratliff, Wired 2019 Other sources - twitter, youtube, tv Chapter 8: Ad fontes-What do the sources say? By focusing on the sources we are able to extract a number of key characteristics to look for: Historical analysis - establishes a couple of key points for historical analysis The bitcoin whitepaper - the most crucial piece of evidence The forums - the p2p forum and later the bitcoin forum are sources where Satoshi discussed with peers about bitcoin The code - the code in itself may also contain clues The blockchain - the record of transactions also provides an insight into the origin of bitcoin Summary - what can the sources tell us? Chapter 9: Motives What were the motives behind the creation of bitcoin Ideology - what can be said about the ideology of the author based on extant sources? Why the synonym? - what could be the reason for the initial and continued secrecy surrounding the inventor? Summary - why did the inventor invent bitcoin and in this particular way? Chapter 10: The social network of early bitcoin Who were the people involved in the beginning of Bitcoin p2p forum communication Bitcoin forum communication Blockchain transactions Summary - what can we learn from looking at the bitcoin initial network Chapter 11: The usual suspects? Rather than pointing definitively to one or another suspect we will try to integrate the knowledge we have gained with the list of known suspects. An evaluation framework - developing an evaluation framework against which to measure the likelihood of any candidate being Satoshi Nakamoto Prime suspects - the suspects that have gained most attention · Hal Finney · Nick Szabo · Dorian Sakamoto · Craig Wright and David Kleiman · Paul Leroux Secondary suspects - suspects that have gained some attention · Vili Lehdonum and Michael Clear · Neal King, Vladimir Oksman, Charles Bry · Hal Finney, Nick Szabo and Adam Back · Shinichi Mochizuki · Ross Ulbricht · Adam Back · Gavin Andresen · Jed McCaleb · Elon Musk · Len Sassaman · Someone else A new primary suspect - as in the movie The Usual Suspects, careful analysis points towards a surprising suspect who is not in the primary field of suspects. Part 3 - Bitcoin in context How is bitcoin viewed in the wider context of human civilization? Bitcoin does not exist in a technological bubble addressing only technological issues. It is firmly situated in a web of themes that are and have been central to human civilization. This may account for its notoriety but needs to be put in context. Chapter 12: Money Since prehistoric times humans have engaged in exchange. This falls in a continuum from barter, through intermediaries as cowry shells, gold and silver coins to purely symbolic means of exchange. The history of money Medium of exchange Unit of account Standard of deferred payment Store of value Types of money · Commodity · Representative money · Fiat · Digital money · Deposits The politics of money Money as a bridge between domains of value Chapter 13: Ownership Proving that you own something has been a central feature of human societies for millenia and disputes have fueled more than its share of violence and conflict. Owners · Private · Public · Corporate · Communal Property · Tangible · Intangible Establishing and policing ownership · National · Transnational Chapter 14: Social organization Human societies have always been characterized by some sort of social organization. The different options have been debated since classical antiquity. This chapter will take a look at the space of social organization and narrow it down to the particular types associated with bitcoin and blockchain. An ancient discussion: Monarchy, Oligarchy and Democracy - and anarchy Centralization vs decentralization Types of social organization in human groups Open source Cypher punks Chapter 15: Religion A rarely debated issue are the religious aspects surrounding Bitcoin and the blockchain movement. But these aspects are nothing new when it comes to human cultures. Understanding this helps explain a lot of the seemingly strange behavior of bitcoin believers without claiming that Bitcoin is an actual religion. The prophet - Satoshi Nakamoto Sacred scriptures- The Bitcoin whitepaper and the forum posts Believers and heathens Cargo cults Millenarianism Part 4 - Blockchain and the future Where can blockchain technology be applied? Where, if anywhere, might we see cryptocurrencies and the blockchain in the future and how might it affect our lives? A case could be made that we are only in the beginning phases of the blockchain now, sometimes called Web3, where the worst of the teething problems are gone and the wild west ethos is receding. Where not to use blockchain - First let us consider a number of areas where blockchain is currently suggested that might not be particularly relevant. Parameters to be tweaked - Bitcoin was the first version of blockchain technology and certain choices were made. But subsequent and future blockchains need not make the same choices. We need to understand how this can be done in order to ascertain the future utility of the blockchain. Transaction speed Energy consumption Degree of centralization Public availability Mining rewards Banking - even though Bitcoin at its outset was antithetical to the banking industry there are particularly good use cases here. Payment - bitcoin may not in itself have been very successful as a payments solution so far but there is no reason why another cryptocurrency will not be. Current payment systems are slow and expensive compared to what the blockchain can offer. International payments Remittance Peer to peer payments Micropayments Certification - building on the ability to serve as a public record there are good reasons that a blockchain can serve as a public record for information about ownership NFTs Real estate Media Contracts - the ability to establish indisputable truth makes it possible to build contracts that automatically execute according to some logic. This can be used for escrow services and delivery of other services as well as insurance. Regulatory compliance - the immutability of the blockchain makes it good for a great number of use cases where fraud has previously been an issue Forensics - the public nature of the blockchain makes it a valuable tool for law enforcement, especially international law enforcement, which has already proven its worth in a number of high profile cases. Supply chain - the blockchain is well suited for keeping track of things movement across time and place. Health - keeping track of health trackers and personal health records could be done on a blockchain Government - in government there are also areas where blockchain may be useful Special purpose tokens Voting Identity Glossary Key concepts described

Legal and political debates surrounding online privacy often focus on the Fourth Amendment''s protection against unreasonable searches and seizures, overlooking the history and future of an equally powerful privacy right: the First Amendment''s protection of anonymity. The United States of Anonymous features extensive and engaging interviews with people involved in the highest profile anonymity cases, as well as with those who have benefited from, and been harmed by, anonymous communications. Through these interviews, Kosseff explores how courts have protected anonymity for decades and, likewise, how law and technology have allowed individuals to control how much, if any, identifying infTrade ReviewAmid surging social media and online speech wars, readers concerned about the future of free speech, privacy, and the law will appreciate Kosseff's ability to deftly place the many-sided anonymity debate in the context of constitutional values and social norms. * Library Journal *Table of ContentsIntroduction Part I: Developing the Right to Anonymity 1.

Book SynopsisModern cryptosystems, used in numerous applications that require secrecy or privacy - electronic mail, financial transactions, medical-record keeping, government affairs, social media etc. - are based on sophisticated mathematics and algorithms that in implementation involve much computer arithmetic. And for speed it is necessary that the arithmetic be realized at the hardware (chip) level. This book is an introduction to the implementation of cryptosystems at that level.The aforementioned arithmetic is mostly the arithmetic of finite fields, and the book is essentially one on the arithmetic of prime fields and binary fields in the context of cryptography. The book has three main parts. The first part is on generic algorithms and hardware architectures for the basic arithmetic operations: addition, subtraction, multiplication, and division. The second part is on the arithmetic of prime fields. And the third part is on the arithmetic of binary fields. The mathematical fundamentals necessary for the latter two parts are included, as are descriptions of various types of cryptosystems, to provide appropriate context.This book is intended for advanced-level students in Computer Science, Computer Engineering, and Electrical and Electronic Engineering. Practitioners too will find it useful, as will those with a general interest in "hard" applications of mathematics.Table of Contents1 Basic Computer Arithmetic.- 2 Mathematical Fundamentals I: Number Theory.- 3 Modular-Arithmetic Cryptosystems.- 4 Modular Reduction.- 5 Modular Addition and Multiplication.- 6 Modular Exponentiation, Inversion, and Division.- 7 Mathematical Fundamentals II: Abstract Algebra.- 8 Elliptic-Curve Basics.- 9 Elliptic-Curve Cryptosystems.- 10 Polynomial-basis arithmetic.- 11 Normal-basis arithmetic.- A Mathematical Proofs.- Index.
