The Science of Secrecy from Ancient Egypt to Quantum Cryptography From the best-selling author of Fermat’s Last Theorem, The Code Book is a history of man’s urge to uncover the secrets of codes, from Egyptian puzzles to modern day computer encryptions.

Cryptology, for millennia a "secret science", is rapidly gaining in practical importance for the protection of communication channels, databases, and software. Beside its role in computerized information systems, cryptology is finding more and more applications inside computer systems and networks, extending to access rights and source file protection. The first part of this book treats secret codes and their uses - cryptography - before moving on to the process of covertly decrypting a secret code - cryptanalysis. Spiced with a wealth of exciting, amusing, and occasionally personal stories from the history of cryptology, and presupposing only elementary mathematical knowledge, this book will also stimulate general readers.

In today's extensively wired world, cryptology is vital for guarding communication channels, databases, and software from intruders. Increased processing and communications speed, rapidly broadening access and multiplying storage capacity tend to make systems less secure over time, and security becomes a race against the relentless creativity of the unscrupulous. The revised and extended third edition of this classic reference work on cryptology offers a wealth of new technical and biographical details. The book presupposes only elementary mathematical knowledge. Spiced with exciting, amusing, and sometimes personal accounts from the history of cryptology, it will interest general a broad readership.

Cipher and decipher codes: transposition and polyalphabetical ciphers, famous codes, typewriter and telephone codes, codes that use playing cards, knots, and swizzle sticks . . . even invisible writing and sending messages through space. 45 diagrams.

This book explores in detail the AI-driven cyber threat landscape, including inherent AI threats and risks that exist in Large Language Models (LLMs), Generative AI applications, and the AI infrastructure. The book highlights hands-on technical approaches to detect security flaws in AI systems and applications utilizing the intelligence gathered from real-world case studies. Lastly, the book presents a very detailed discussion of the defense mechanisms and practical solutions to secure LLMs, GenAI applications, and the AI infrastructure. The chapters are structured with a granular framework, starting with AI concepts, followed by practical assessment techniques based on real-world intelligence, and concluding with required security defenses. Artificial Intelligence (AI) and cybersecurity are deeply intertwined and increasingly essential to modern digital defense strategies. The book is a comprehensive resource for IT professionals, business leaders, and cybersecurity experts for understanding and defending against AI-driven cyberattacks. FEATURES: Includes real-world case studies with detailed examples of AI-centric attacks and defense mechanisms Features hands-on security assessments with practical techniques for evaluating the security of AI systems Demonstrates advanced defense strategies with proven methods to protect LLMs, GenAI applications, and the infrastructure

Theories of evolution, origin of the Universe, and deep time, have led many scientists like my former self, to conclude that Creation is just a chance sequence of events that can ultimately be explained by natural laws. I was skeptical and even tried to disprove God's existence, until I found a Secret Code embedded in the Scriptures. This code provides undeniable evidence of God, based upon event sequences in the lives of a Great Cloud of Witnesses like Joseph, Samson, David, Jonah, Elisha, Moses, and Joshua. By unlocking the Earthly Sanctuary pattern given to Moses, I've found that it reveals events of the Exodus from Egypt to the Promised Land which even applies to Spiritual Israel today. The veil to the Holy Place aligns with the Exodus opening of the Red Sea. And the veil to the Holiest Place points to the opening of the Jordan where we now stand, waiting to cross at the End of Time. The code reveals probabilities of the existence of God, far greater than finding an atom in Planet Earth by chance.

Poison dart umbrellas and cyanide guns were all a part of the arsenal of tools used by spies of the Soviet KGB, American CIA, and British MI6, but you won't learn that in your history books! Learn the true stories of the Cold War and how spies used listening devices planted in live cats and wristwatch cameras. Discover how East Germans tried to ride zip lines to freedom, while the Cambridge Four infiltrated Britain and rockets raced to the moon. Then make your own submarines and practice writing secret codes. It's all part of the true stories from the Top Secret Files: The Cold War. Take a look if you dare, but be careful!
