Book Synopsis Secrets of Making and Breaking Codes by : Hamilton Nickels
Download or read book Secrets of Making and Breaking Codes written by Hamilton Nickels and published by Skyhorse. This book was released on 2014-07-15 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since humans first began to communicate, we’ve had secrets to keep — secrets of state, war, business, or the heart. From the moment the first secret message was sent, others were busy trying to decipher it. By rearranging, substituting, or transposing symbols, any message can be encoded or decoded — if you know how. Secrets of Making and Breaking Codes is a practical field manual designed to teach you the basic mechanics of enciphering and deciphering communications. The author has used his extensive knowledge of and experience in electronic communications and languages — as well as his decades of fascination with secret codes — to demystify the field of cryptology. Hamilton Nickels uses plain, uncomplicated English and simple, workable systems that rely on neither advanced mathematics, nor on ethereal philosophies. This is the only hands-on guide to both the simplest cipher schemes — that need little more than scratch paper and a pencil to crack — as well as more sophisticated codes that use one-time code books, pocket calculators, and the most advanced computer-based systems used by the military and diplomatic corps of most governments. Letting the wrong eyes see a secret message can often make the difference between victory and defeat, success and failure, life and death. Secrets of Making and Breaking Codes will make mastering codes easier.

Download or read book Code Girls written by Liza Mundy and published by Hachette Books. This book was released on 2017-10-10 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.
Download or read book Cryptography written by Various and published by Rosen Young Adult. This book was released on 2016-12-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data encryption and security is an increasingly relevant subject in our digitized world. Cryptography is used to make e-commerce and online communication secure, protecting banking information, sensitive documents, and more. When you purchase something online or send a confidential e-mail, protocols created by cryptographers protect that information. However, if your private information is hacked electronically, cryptographers are also to blame. This series sheds light on the history of cryptography, the "arms race" between those protecting sensitive information and those trying to access it, the lives of famous cryptographers, and the tools and methods that cryptographers use.

Available in PDF, EPUB and Kindle. Book excerpt: Learn how to program in Python while making and breaking ciphers—algorithms used to create and send secret messages! After a crash course in Python programming basics, you’ll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenère cipher. You’ll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure today’s online transactions, including digital signatures, email, and Bitcoin. Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, you’ll have learned how to code in Python and you’ll have the clever programs to prove it! You’ll also learn how to: - Combine loops, variables, and flow control statements into real working programs - Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish - Create test programs to make sure that your code encrypts and decrypts correctly - Code (and hack!) a working example of the affine cipher, which uses modular arithmetic to encrypt a message - Break ciphers with techniques such as brute-force and frequency analysis There’s no better way to learn to code than to play with real programs.

Book Synopsis Code Breaking in the Pacific by : Peter Donovan
Download or read book Code Breaking in the Pacific written by Peter Donovan and published by Springer. This book was released on 2016-09-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945. It traces the all-important genesis and development of the cryptanalytic techniques used to break the main Japanese Navy code (JN-25) and the Japanese Army’s Water Transport Code during WWII. This is the first book to describe, explain and analyze the code breaking techniques developed and used to provide this intelligence, thus closing the sole remaining gap in the published accounts of the Pacific War. The authors also explore the organization of cryptographic teams and issues of security, censorship, and leaks. Correcting gaps in previous research, this book illustrates how Sigint remained crucial to Allied planning throughout the war. It helped direct the advance to the Philippines from New Guinea, the sea battles and the submarine onslaught on merchant shipping. Written by well-known authorities on the history of cryptography and mathematics, Code Breaking in the Pacific is designed for cryptologists, mathematicians and researchers working in communications security. Advanced-level students interested in cryptology, the history of the Pacific War, mathematics or the history of computing will also find this book a valuable resource.
Book Synopsis Breaking the Code by : Karen Fisher-Alaniz
Download or read book Breaking the Code written by Karen Fisher-Alaniz and published by Sourcebooks, Inc.. This book was released on 2011-11-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: On his 81st birthday, without explanation, Karen Fisher-Alaniz's father placed two weathered notebooks on her lap. Inside were more than 400 pages of letters he'd written to his parents during WWII. She began reading them, and the more she read, the more she discovered about the man she never knew. They began to meet for lunch every week, for her to ask him questions, and him to provide the answers. It was through this process that she discovered the secret role he played in WWII. Karen's father was part of a small and elite group of men who were trained to copy and break top-secret Japanese code transmitted in Katakana. Through this journey, with painful memories now at the forefront of his thoughts, Karen's father began to suffer, making their meetings as much about healing as discovery. Thus began an unintended journey—one taken by a father and daughter who thought they knew each other—as they became newly bound in ways that transcended age and time.
