The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptography--the science of sending secret messages. Most books about cryptography are organized historically, or around how codes and ciphers have been used, such as in government and military intelligence or bank transactions. Joshua Holden instead shows how mathematical principles underpin the ways that different codes and ciphers operate. Holden focuses on both code making and code breaking and he discusses the majority of ancient and modern ciphers currently known.
Holden begins by looking at substitution ciphers, built by substituting one letter or block of letters for another. Explaining one of the simplest and historically well-known ciphers, the Caesar cipher, Holden establishes the key mathematical idea behind the cipher and discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, including one developed by the Spartans, connections between ciphers and computer encryption, stream ciphers, and ciphers involving exponentiation. He also examines public-key ciphers, where the methods used to encrypt messages are public knowledge, and yet, intended recipients are still the only ones who are able to read the message. He concludes with a look at the future of ciphers and where cryptography might be headed. Only basic mathematics up to high school algebra is needed to understand and enjoy the book.
With a plethora of historical anecdotes and real-world examples, The Mathematics of Secrets reveals the mathematics working stealthily in the science of coded messages.

Описание: This vintage book contains Alexander D'Agapeyeff's famous 1939 work, "Codes and Ciphers - A History of Cryptography". Cryptography is the employment of codes and ciphers to protect secrets, and it has a long and interesting history. This fantastic volume offers a detailed history of cryptography from ancient times to modernity, written by the Russian-born English cryptographer, Alexander D'Agapeyeff. Contents include: "The beginnings of Cryptography", "From the Middle Ages Onwards", "Signals, Signs, and Secret Languages", "Commercial Codes", "Military Codes and Ciphers", "Types of Codes and Ciphers", "Methods of Deciphering", etcetera. Many antiquarian texts such as this, especially those dating back to the 1900s and before, are increasingly hard to come by and expensive, and it is with this in mind that we are republishing this book now in an affordable, modern, high quality edition. It comes complete with a specially commissioned new biography of the author.

A 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 and an enciphered message taped to his abdomen. 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. He lays out the evidence surrounding each cipher, describes the efforts to decipher it, and invites readers to try their hand at puzzles that have stymied so many others.

As Samuel Richardson's 'exemplar to her sex,’ Clarissa in the eponymous novel published in 1748 is the paradigmatic female victim. In Clarissa’s Ciphers, Terry Castle delineates the ways in which, in a world where only voice carries authority, Clarissa is repeatedly silenced, both metaphorically and literally. A victim of rape, she is first a victim of hermeneutic abuse. Drawing on feminist criticism and hermeneutic theory, Castle examines the question of authority in the novel. By tracing the patterns of abuse and exploitation that occur when meanings are arbitrarily and violently imposed, she explores the sexual politics of reading.

Описание: This Festschrift honours the dedicated book historian and medievalist Gabriele M?ller-Oberh?user. Her wide-ranging scholarly expertise has encouraged and influenced many adepts of the book. The essays in this volume reflect the variety of her interests: The contributions range from Chaucer’s F?rstenspiegel to the value of books in comedy, from the material book to the magical book in religious and literary cultures, from collaborative efforts in manuscript production to the relations of distributors of books across national and ideological boundaries, from the relations between the makers of books to the relation of readers to their books. Covering a period from the Middle Ages to the present, the volume concludes with a look at the future of book history as a field of study.

Описание: Death is not only the final moment of life, it also casts a huge shadow on human society at large. People throughout time have had to cope with death as an existential experience, and this also, of course, in the premodern world. The contributors to the present volume examine the material and spiritual conditions of the culture of death, studying specific buildings and spaces, literary works and art objects, theatrical performances, and medical tracts from the early Middle Ages to the late eighteenth century. Death has always evoked fear, terror, and awe, it has puzzled and troubled people, forcing theologians and philosophers to respond and provide answers for questions that seem to evade real explanations. The more we learn about the culture of death, the more we can comprehend the culture of life. As this volume demonstrates, the approaches to death varied widely, also in the Middle Ages and the early modern age. This volume hence adds a significant number of new facets to the critical examination of this ever-present phenomenon of death, exploring poetic responses to the Black Death, types of execution of a female murderess, death as the springboard for major political changes, and death reflected in morality plays and art.
