Book Description
The global crisis of Privacy in the 21st century also includes discussions about the right to encryption and restrictions on so-called end-to-end encryption. In order to communicate confidentially and secure against eavesdropping, simple and practical encryption is required for everyone. But how can it be available to everyone? The magic of replacing legible characters with other apparently random and therefore illegible characters had been almost religious for centuries: only those initiated into the invention of a secret language could crack the messages. Encryption remained Super Secreto - Top Secret - Streng Geheim! In the age of smartphone and pocket computers, it is now available to everyone: ever more sophisticated math calculates the so-called cipher text with corresponding keys in our messengers. Both keys and encrypted text used to have to be transmitted to the recipient. In today's Epoch of Cryptography, the transmission of the keys is no longer necessary: The risky transport route for the keys can even be omitted! From the fascination of how Cryptography became abstinent in the transmission of keys - what effect it has on the desire of state agencies for secondary keys - and how multiple and exponential encryption makes resistant against the decryption-attempts of super-quantum-computers ... ... tells Theo Tenzer in this exciting political, technical and socially relevant innovation and science portrait on the Third Epoch of Cryptography.

Book Description
Human Proxies offer new directions to end-to-end encryption: End-A-to-End-Z encryption must be rethought when it turns out to be an End-B-to-End-Z encryption. And, Human Proxies raise questions that were neither answered by science, journalists nor the public. Regular Proxies on a network are forwarding Internet requests, e.g., to download a webpage. Also, in political and social settings a Proxy as an intermediate, deputy or representative with a similar function is given. Human Proxies now enable within the Encryption and Messenger Application Spot-On to choose a friend as a Human Proxy. The Spot-On program is a most modern and elaborated encryption suite available for several operation systems and provides many innovations in applied cryptography. It builds based on the Echo Protocol a cryptographic network, that is beyond Cryptographic Routing. With Human Proxies now a friend from the Messenger friends list sends out the chat message instead of the original sender. The construct of the "Inner Envelope" behind the Human Proxy function also creates new cryptographic challenges, provides plausible deniability to included nodes, and offers new perspectives in encryption, its analysis and decryption: As all messages in the network are encrypted, end-to-end encryption is new defined and gets with Human Proxies a potential second and plausible deniable start point. The essay in this book discusses some related aspects of Human Proxies and their referring's to encryption, networking, graph theory and comparable social and political processes of Proxies. This leads to a further general approach: Endpoints in Encryption are equipped by the application Spot-On with the vision of interoperability of endpoints in communications. | English & German language.

Book Description
This practical guide to modern encryption breaks down the fundamental mathematical concepts at the heart of cryptography without shying away from meaty discussions of how they work. You’ll learn about authenticated encryption, secure randomness, hash functions, block ciphers, and public-key techniques such as RSA and elliptic curve cryptography. You’ll also learn: - Key concepts in cryptography, such as computational security, attacker models, and forward secrecy - The strengths and limitations of the TLS protocol behind HTTPS secure websites - Quantum computation and post-quantum cryptography - About various vulnerabilities by examining numerous code examples and use cases - How to choose the best algorithm or protocol and ask vendors the right questions Each chapter includes a discussion of common implementation mistakes using real-world examples and details what could go wrong and how to avoid these pitfalls. Whether you’re a seasoned practitioner or a beginner looking to dive into the field, Serious Cryptography will provide a complete survey of modern encryption and its applications.

Book Description
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. Cracking Codes with Python makes the learning fun!

Book Description
Cryptography is hard, but it’s less hard when it’s filled with adorable Japanese manga. The latest addition to the Manga Guide series, The Manga Guide to Cryptography, turns the art of encryption and decryption into plain, comic illustrated English. As you follow Inspector Jun Meguro in his quest to bring a cipher-wielding thief to justice, you’ll learn how cryptographic ciphers work. (Ciphers are the algorithms at the heart of cryptography.) Like all books in the Manga Guide series, The Manga Guide to Cryptography is illustrated throughout with memorable Japanese manga as it dives deep into advanced cryptography topics, such as classic substitution, polyalphabetic, and transposition ciphers; symmetric-key algorithms like block and DES (Data Encryption Standard) ciphers; and how to use public key encryption technology. It also explores practical applications of encryption such as digital signatures, password security, and identity fraud countermeasures. The Manga Guide to Cryptography is the perfect introduction to cryptography for programmers, security professionals, aspiring cryptographers, and anyone who finds cryptography just a little bit hard.

Book Description
In this age of genetic engineering and global warming, it is more important than ever to understand the history and current trends of science and technology. With so much information out there, though, it's hard to know where to start. That's where The History of Science and Technology -- the most comprehensive and up-to-date chronology of its kind -- comes in. From the first stone tools to the first robot surgery, this easy-to-read, handy reference book offers more than seven thousand concise entries organized within ten major historical periods and categorized by subject, such as archaeology, biology, computers, food and agriculture, medicine and health, materials, and transportation. You can follow the world's scientific and technological feats forward or backward, year by year, and subject by subject. Under 8400 BCE Construction, you will discover that the oldest known wall was built in Jericho. Jump to 1454 Communication and you will learn about Johann Gutenberg's invention of movable type. Take an even larger leap to 2002 Computers and find out about the invention of the Earth Simulator, a Japanese supercomputer. The History of Science and Technology answers all the what, when, why, and how questions about our world's greatest discoveries and inventions: How are bridges built? When were bifocal eyeglasses invented and by whom? What medical discovery led to the introduction of sterilization, vaccines, and antibiotics? What is the PCR (polymerase chain reaction) process, and why is it one of the pillars of the biotechnology revolution?
