THE CIPHER by Kathe Koja Pdf

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

The Cipher by Isabella Maldonado Pdf

To a cunning serial killer, she was the one that got away. Until now... FBI Special Agent Nina Guerrera escaped a serial killer's trap at sixteen. Years later, when she's jumped in a Virginia park, a video of the attack goes viral. Legions of new fans are not the only ones impressed with her fighting skills. The man who abducted her eleven years ago is watching. Determined to reclaim his lost prize, he commits a grisly murder designed to pull her into the investigation...but his games are just beginning. And he's using the internet to invite the public to play along. His coded riddles may have made him a depraved social media superstar--an enigmatic cyber-ghost dubbed "the Cipher"--but to Nina he's a monster who preys on the vulnerable. Partnered with the FBI's preeminent mind hunter, Dr. Jeffrey Wade, who is haunted by his own past, Nina tracks the predator across the country. Clue by clue, victim by victim, Nina races to stop a deadly killer while the world watches.

Stream Ciphers by Andreas Klein Pdf

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.

Stream Ciphers in Modern Real-time IT Systems by Alexandr Alexandrovich Kuznetsov,Oleksandr Volodymyrovych Potii,Nikolay Alexandrovich Poluyanenko,Yurii Ivanovich Gorbenko,Natalia Kryvinska Pdf

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.

The Block Cipher Companion by Lars R. Knudsen,Matthew Robshaw Pdf

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.

Mathematical Ciphers by Anne L. Young Pdf

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.

Codes, Ciphers and Spies by John F. Dooley Pdf

When the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

Data-driven Block Ciphers for Fast Telecommunication Systems by Nikolai Moldovyan,Alexander A. Moldovyan Pdf

The Most Progressive and Complete Guide to DDO-Based Ciphers Developers have long recognized that ciphers based on Permutation Networks (PNs) and Controlled Substitution-Permutation Networks (CSPNs) allow for the implementation of a variety of Data Driven Operations (DDOs). These DDOs can provide fast encryption without incurring excessive hardware costs in modern telecommunication networks. However, until now, with a few exceptions, most DDO-based ciphers have been poorly represented in available literature and have continued to remain known to only a small number of encryption experts. In Data-Driven Block Ciphers for Fast Telecommunication Systems, Nikolai Moldovyan and Alexander Moldovyan, major innovators and holders of several dozen international patents in encryption technology, provide the background and detail the applications needed to investigate new properties of PNs especially relevant to the improvement of modern wireless systems.Furthermore, they propose a universal architecture involving controlled bit permutation instruction that will permit the performance of both data-driven permutations and an arbitrary prescribed fixed permutation in a single cycle. Immediately improved efficiency for current and future fast telecommunication systems and mobile networks Because of its simplicity and efficient use of current hardware, the embedding of this architecture is a highly attractive option for CPU manufacturers.By detailing all the relevant information into a single volume for the first time, the authors of this book make that option more feasible than ever before.
