Secret Key Cryptography

Explore the fascinating and rich world of Secret Key cryptography! This book provides practical methods for encrypting messages, an interesting and entertaining historical perspective, and an incredible collection of ciphers and codesincluding 30 unbreakable methods.In Secret Key Cryptography: Ciphers, from simple to unbreakable you will:Measure the strength of your ciphers and learn how to guarantee their securityConstruct and incorporate data-compression codesGenerate true random numbers in bulkConstruct huge primes and safe primesAdd an undetectable backdoor to a cipherDefeat hypothetical ultracomputers that could be developed decades from nowConstruct 30 unbreakable ciphersSecret Key Cryptography gives you a toolbox of cryptographic techniques and Secret Key methods. The book's simple, non-technical language is easy to understand and accessible for any reader, even without the advanced mathematics normally required for cryptography. You'll learn how to create and solve ciphers, as well as how to measure their strength. As you go, you'll explore both historic ciphers and groundbreaking new approachesincluding a never-before-seen way to implement the uncrackable One-Time Pad algorithm.
