Book excerpt: Kathe Koja's classic, award-winning horror novel is finally available as an ebook. Nicholas, a would-be poet, and Nakota, his feral lover, discover a strange hole in the storage room floor down the hall - "Black. Pure black and the sense of pulsation, especially when you look at it too closely, the sense of something not living but alive." It begins with curiosity, a joke - the Funhole down the hall. But then the experiments begin. "Wouldn't it be wild to go down there?" says Nakota. Nicholas says "We're not." But they're not in control, not from the first moment, as those experiments lead to obsession, violence, and a very final transformation for everyone who gets too close to the Funhole. THE CIPHER was the winner of the 1991 Bram Stoker Award, and was recently named one of io9.com's Top 10 Debut Science Fiction Novels That Took the World By Storm. Long out-of-print and much sought-after, it is finally available as an ebook, with a new foreword by the author. "An ethereal rollercoaster ride from start to finish." - The Detroit Free Press "Combines intensely poetic language and lavish grotesqueries." - BoingBoing "Kathe Koja is a poet ... [T]he kind that prefers to read in seedy bars instead of universities, but a poet." - The New York Review of Science Fiction "Her 20-something characters are poverty-gagged 'artists' who exist in that demimonde of shitty jobs, squalid art galleries, and thrift stores; her settings are run-down studios, flat-beer bars, and dingy urban streets [a] long way from Castle Rock, Dunwich, or Stepford, that's for sure." - Too Much Horror Fiction "This powerful first novel is as thought-provoking as it is horrifying." - Publishers Weekly "Unforgettable ... [THE CIPHER] takes you into the lives of the dark dreamers that crawl on the underbelly of art and culture. Seldom has language been so visceral and so right." - Locus "[THE CIPHER] is a book that makes you sit up, pay attention, and jettison your moldy preconceptions about the genre ... Utterly original ... [An} imaginative debut." - Fangoria "Not so much about the vast and wonderful strangeness of the universe as it is about the horrific and glorious potential of the human spirit." - Short Form

Download or read book American Cipher written by Matt Farwell and published by Penguin. This book was released on 2020-03-10 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosive narrative of the life, captivity, and trial of Bowe Bergdahl, the soldier who was abducted by the Taliban and whose story has served as a symbol for America's foundering war in Afghanistan ”An unsettling and riveting book filled with the mysteries of human nature.” —Kirkus Private First Class Bowe Bergdahl left his platoon's base in eastern Afghanistan in the early hours of June 30, 2009. Since that day, easy answers to the many questions surrounding his case—why did he leave his post? What kinds of efforts were made to recover him from the Taliban? And why, facing a court martial, did he plead guilty to the serious charges against him?—have proved elusive. Taut in its pacing but sweeping in its scope, American Cipher is the riveting and deeply sourced account of the nearly decade-old Bergdahl quagmire—which, as journalists Matt Farwell and Michael Ames persuasively argue, is as illuminating an episode as we have as we seek the larger truths of how the United States lost its way in Afghanistan. The book tells the parallel stories of a young man's halting coming of age and a nation stalled in an unwinnable war, revealing the fallout that ensued when the two collided: a fumbling recovery effort that suppressed intelligence on Bergdahl's true location and bungled multiple opportunities to bring him back sooner; a homecoming that served to deepen the nation's already-vast political fissure; a trial that cast judgment on not only the defendant, but most everyone involved. The book's beating heart is Bergdahl himself—an idealistic, misguided soldier onto whom a nation projected the political and emotional complications of service. Based on years of exclusive reporting drawing on dozens of sources throughout the military, government, and Bergdahl's family, friends, and fellow soldiers, American Cipher is at once a meticulous investigation of government dysfunction and political posturing, a blistering commentary on America's presence in Afghanistan, and a heartbreaking story of a naïve young man who thought he could fix the world and wound up the tool of forces far beyond his understanding.

Download or read book The Block Cipher Companion written by Lars R. Knudsen and published by Springer Science & Business Media. This book was released on 2011-10-25 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Block ciphers encrypt blocks of plaintext, messages, into blocks of ciphertext under the action of a secret key, and the process of encryption is reversed by decryption which uses the same user-supplied key. Block ciphers are fundamental to modern cryptography, in fact they are the most widely used cryptographic primitive – useful in their own right, and in the construction of other cryptographic mechanisms. In this book the authors provide a technically detailed, yet readable, account of the state of the art of block cipher analysis, design, and deployment. The authors first describe the most prominent block ciphers and give insights into their design. They then consider the role of the cryptanalyst, the adversary, and provide an overview of some of the most important cryptanalytic methods. The book will be of value to graduate and senior undergraduate students of cryptography and to professionals engaged in cryptographic design. An important feature of the presentation is the authors' exhaustive bibliography of the field, each chapter closing with comprehensive supporting notes.

Download or read book Stream Ciphers written by Andreas Klein and published by Springer Science & Business Media. This book was released on 2013-04-08 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: In cryptography, ciphers is the technical term for encryption and decryption algorithms. They are an important sub-family that features high speed and easy implementation and are an essential part of wireless internet and mobile phones. Unlike block ciphers, stream ciphers work on single bits or single words and need to maintain an internal state to change the cipher at each step. Typically stream ciphers can reach higher speeds than block ciphers but they can be more vulnerable to attack. Here, mathematics comes into play. Number theory, algebra and statistics are the key to a better understanding of stream ciphers and essential for an informed decision on their safety. Since the theory is less developed, stream ciphers are often skipped in books on cryptography. This book fills this gap. It covers the mathematics of stream ciphers and its history, and also discusses many modern examples and their robustness against attacks. Part I covers linear feedback shift registers, non-linear combinations of LFSRs, algebraic attacks and irregular clocked shift registers. Part II studies some special ciphers including the security of mobile phones, RC4 and related ciphers, the eStream project and the blum-blum-shub generator and related ciphers. Stream Ciphers requires basic knowledge of algebra and linear algebra, combinatorics and probability theory and programming. Appendices in Part III help the reader with the more complicated subjects and provides the mathematical background needed. It covers, for example, complexity, number theory, finite fields, statistics, combinatorics. Stream Ciphers concludes with exercises and solutions and is directed towards advanced undergraduate and graduate students in mathematics and computer science.

Download or read book Stream Ciphers in Modern Real time IT Systems written by Alexandr Alexandrovich Kuznetsov and published by Springer Nature. This book was released on 2021-11-19 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the most complete description, analysis, and comparative studies of modern standardized and most common stream symmetric encryption algorithms, as well as stream modes of symmetric block ciphers. Stream ciphers provide an encryption in almost real-time regardless of the volume and stream bit depth of converted data, which makes them the most popular in modern real-time IT systems. In particular, we analyze the criteria and performance indicators of algorithms, as well as the principles and methods of designing stream ciphers. Nonlinear-feedback shift registers, which are one of the main elements of stream ciphers, have been studied in detail. The book is especially useful for scientists, developers, and experts in the field of cryptology and electronic trust services, as well as for the training of graduate students, masters, and bachelors in the field of information security.

Download or read book Mathematical Ciphers written by Anne L. Young and published by American Mathematical Soc.. This book was released on 2006 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cipher is a scheme for creating coded messages for the secure exchange of information. Throughout history, many different coding schemes have been devised. One of the oldest and simplest mathematical systems was used by Julius Caesar. This is where Mathematical Ciphers begins. Building on that simple system, Young moves on to more complicated schemes, ultimately ending with the RSA cipher, which is used to provide security for the internet. This book is structured differently from most mathematics texts. It does not begin with a mathematical topic, but rather with a cipher. The mathematics is developed as it is needed; the applications motivate the mathematics. As is typical in mathematics textbooks, most chapters end with exercises. Many of these problems are similar to solved examples and are designed to assist the reader in mastering the basic material. A few of the exercises are one-of-a-kind, intended to challenge the interested reader. Implementing encryption schemes is considerably easier with the use of the computer. For all the ciphers introduced in this book, JavaScript programs are available from the web. In addition to developing various encryption schemes, this book also introduces the reader to number theory. Here, the study of integers and their properties is placed in the exciting and modern context of cryptology. Mathematical Ciphers can be used as a textbook for an introductory course in mathematics for all majors. The only prerequisite is high school mathematics.
