| crude cipher further instructions: A Methodology for the Cryptanalysis of Classical Ciphers with Search Metaheuristics George Lasry, 2018 Cryptography, the art and science of creating secret codes, and cryptanalysis, the art and science of breaking secret codes, underwent a similar and parallel course during history. Both fields evolved from manual encryption methods and manual codebreaking techniques, to cipher machines and codebreaking machines in the first half of the 20th century, and finally to computerbased encryption and cryptanalysis from the second half of the 20th century. However, despite the advent of modern computing technology, some of the more challenging classical cipher systems and machines have not yet been successfully cryptanalyzed. For others, cryptanalytic methods exist, but only for special and advantageous cases, such as when large amounts of ciphertext are available. Starting from the 1990s, local search metaheuristics such as hill climbing, genetic algorithms, and simulated annealing have been employed, and in some cases, successfully, for the cryptanalysis of several classical ciphers. In most cases, however, results were mixed, and the application of such methods rather limited in their scope and performance. In this work, a robust framework and methodology for the cryptanalysis of classical ciphers using local search metaheuristics, mainly hill climbing and simulated annealing, is described. In an extensive set of case studies conducted as part of this research, this new methodology has been validated and demonstrated as highly effective for the cryptanalysis of several challenging cipher systems and machines, which could not be effectively cryptanalyzed before, and with drastic improvements compared to previously published methods. This work also led to the decipherment of original encrypted messages from WWI, and to the solution, for the first time, of several public cryptographic challenges. |

D'Imperio, 1978 In spite of all the papers that others have written about the manuscript, there is no complete survey of all the approaches, ideas, background information and analytic studies that have accumulated over the nearly fifty-five years since the manuscript was discovered by Wilfrid M. Voynich in 1912. This report pulls together all the information the author could obtain from all the sources she has examined, and to present it in an orderly fashion. The resulting survey will provide a firm basis upon which other students may build their work, whether they seek to decipher the text or simply to learn more about the problem. |
| crude cipher further instructions: The Sword and the Shield Christopher Andrew, 2000-08-29 The Sword and the Shield is based on one of the most extraordinary intelligence coups of recent times: a secret archive of top-level KGB documents smuggled out of the Soviet Union which the FBI has described, after close examination, as the most complete and extensive intelligence ever received from any source. Its presence in the West represents a catastrophic hemorrhage of the KGB's secrets and reveals for the first time the full extent of its worldwide network. Vasili Mitrokhin, a secret dissident who worked in the KGB archive, smuggled out copies of its most highly classified files every day for twelve years. In 1992, a U.S. ally succeeded in exfiltrating the KGB officer and his entire archive out of Moscow. The archive covers the entire period from the Bolshevik Revolution to the 1980s and includes revelations concerning almost every country in the world. But the KGB's main target, of course, was the United States. Though there is top-secret material on almost every country in the world, the United States is at the top of the list. As well as containing many fascinating revelations, this is a major contribution to the secret history of the twentieth century. Among the topics and revelations explored are: The KGB's covert operations in the United States and throughout the West, some of which remain dangerous today. KGB files on Oswald and the JFK assassination that Boris Yeltsin almost certainly has no intention of showing President Clinton. The KGB's attempts to discredit civil rights leader in the 1960s, including its infiltration of the inner circle of a key leader. The KGB's use of radio intercept posts in New York and Washington, D.C., in the 1970s to intercept high-level U.S. government communications. The KGB's attempts to steal technological secrets from major U.S. aerospace and technology corporations. KGB covert operations against former President Ronald Reagan, which began five years before he became president. KGB spies who successfully posed as U.S. citizens under a series of ingenious disguises, including several who attained access to the upper echelons of New York society. |
| crude cipher further instructions: Blindsight Peter Watts, 2006-10-03 Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied. |

| crude cipher further instructions: Victorian Detective Fiction and the Nature of Evidence L. Frank, 2003-07-02 Frank investigates an intertextual exchange between nineteenth-century historical disciplines (philology, cosmology, geology archaeology and evolutionary biology) and the detective fictions of Poe, Dickens, and Doyle. In responding to the writings of figures like Lyell, Darwin and E.B. Taylor, detective fiction initiated a transition from scriptural literalism and a prevailing Natural Theology to a naturalistic, secular worldview. In the process, detective fiction sceptically examined both the evidence such disciplines used and their narrative rendering of the world. |
| crude cipher further instructions: Terminal World Alastair Reynolds, 2021-12-21 In the last surviving human city, an ex-spy gets sucked into a dangerous quest that will take him beyond the city walls when a winged man turns up dead in his morgue in this innovative and original dystopian space adventure. Spearpoint, the last human city, is an enormous atmosphere-piercing spire. Clinging to its skin are the zones, a series of semi-autonomous city-states, each of which enjoys a different—and rigidly enforced—level of technology. Following an infiltration mission that went tragically wrong, Quillon has been living incognito, working as a pathologist in the district morgue. But when a near-dead angel drops onto his dissecting table, Quillon's world is wrenched apart one more time, for the angel is a winged posthuman from Spearpoint's Celestial Levels—and with the dying body comes bad news. If Quillon is to save his life, he must leave his home and journey into the cold and hostile lands beyond Spearpoint's base, starting an exile that will take him further than he could ever imagine. But there is far more at stake than just Quillon's own survival, for the limiting technologies of the zones are determined not by governments or police, but by the very nature of reality—and reality itself is showing worrying signs of instability . . . |

| crude cipher further instructions: The Secret of Our Success Joseph Henrich, 2017-10-17 How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness. |
