SUPER SECRETO - The Third Epoch of Cryptography by Theo Tenzer Pdf

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.

Human Proxies in Cryptographic Networks by Uni Nurf Pdf

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.

Introduction to Cryptography and Network Security by Behrouz A. Forouzan Pdf

In this new first edition, well-known author Behrouz Forouzan uses his accessible writing style and visual approach to simplify the difficult concepts of cryptography and network security. While many security books assume knowledge of number theory and advanced math, or present mainly theoretical ideas, Forouzan presents difficult security topics from the ground up. A gentle introduction to the fundamentals of number theory is provided in the opening chapters, paving the way for the student to move on to more complex security and cryptography topics. Difficult math concepts are organized in appendices at the end of each chapter so that students can first learn the principles, then apply the technical background. Hundreds of examples, as well as fully coded programs, round out a practical, hands-on approach which encourages students to test the material they are learning.

Number Theory and Cryptography by Marc Fischlin,Stefan Katzenbeisser Pdf

Johannes Buchmann is internationally recognized as one of the leading figures in areas of computational number theory, cryptography and information security. He has published numerous scientific papers and books spanning a very wide spectrum of interests; besides R&D he also fulfilled lots of administrative tasks for instance building up and directing his research group CDC at Darmstadt, but he also served as the Dean of the Department of Computer Science at TU Darmstadt and then went on to become Vice President of the university for six years (2001-2007). This festschrift, published in honor of Johannes Buchmann on the occasion of his 60th birthday, contains contributions by some of his colleagues, former students and friends. The papers give an overview of Johannes Buchmann's research interests, ranging from computational number theory and the hardness of cryptographic assumptions to more application-oriented topics such as privacy and hardware security. With this book we celebrate Johannes Buchmann's vision and achievements.

Cracking Codes with Python by Al Sweigart Pdf

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!

Figurative Inquisitions by Erin Graff Zivin Pdf

Winner, 2015 LAJSA Best Book in Latin American Jewish Studies The practices of interrogation, torture, and confession have resurfaced in public debates since the early 2000s following human rights abuses around the globe. Yet discussion of torture has remained restricted to three principal fields: the legal, the pragmatic, and the moral, eclipsing the less immediate but vital question of what torture does.Figurative Inquisitions seeks to correct this lacuna by approaching the question of torture from a literary vantage point. This book investigates the uncanny presence of the Inquisition and marranismo (crypto-Judaism) in modern literature, theater, and film from Mexico, Brazil, and Portugal. Through a critique of fictional scenes of interrogation, it underscores the vital role of the literary in deconstructing the relation between torture and truth. Figurative Inquisitions traces the contours of a relationship among aesthetics, ethics, and politics in an account of the "Inquisitional logic" that continues to haunt contemporary political forms. In so doing, the book offers a unique humanistic perspective on current torture debates.
