Cryptography is the practice and study of secure communication. In the old times, cryptography was all about writing messages between that intruders couldn't read or understand. People wrote ciphers and keys and worked hard to decrypt and encrypt important notes. Cryptography was confined mostly to military and diplomatic activities, while regular people didn't have much to do with it in ordinary life. With the development of modern cryptography, we are now surrounded by its codes everywhere. Every message you send over your phone is encrypted. Our banks, schools, and governments rely on secure encryptions. With its prominence in our daily lives, it's a good idea to learn a thing or two about cryptography - not to mention interesting! Here's what you'll find in this book: History of encryption Cyphers from the Classical Era Introduction to modern cryptography Quantum cryptography Hash functions and digital signatures Public key infrastructure AND SO MUCH MORE!

Using the quantum properties of single photons to exchange binary keys between two partners for subsequent encryption of secret data is an absolutely novel te- nology. Only a few years ago quantum cryptography – or better Quantum Key Distribution – was the domain of basic research laboratories at universities. But during the last few years things changed. Quantum Key Distribution or QKD left the laboratories and was picked up by more practical-oriented teams that worked hard to develop a practically applicable technology out of the astonishing results of basic research. One major milestone toward a QKD technology was a large research and dev- opment project funded by the European Commission that aimed at combining qu- tum physics with complementary technologies that are necessary to create a tech- cal solution: electronics, software, and network components were added within the project SECOQC (Development of a Global Network for Secure Communication based on Quantum Cryptography) that teamed up all expertise on European level to get a technology for future cryptography.

Cryptography is concerned with the conceptualization, definition and construction of computing systems that address security concerns. The design of cryptographic systems must be based on firm foundations. Foundations of Cryptography presents a rigorous and systematic treatment of foundational issues, defining cryptographic tasks and solving cryptographic problems. The emphasis is on the clarification of fundamental concepts and on demonstrating the feasibility of solving several central cryptographic problems, as opposed to describing ad-hoc approaches. This second volume contains a thorough treatment of three basic applications: Encryption, Signatures, and General Cryptographic Protocols. It builds on the previous volume, which provided a treatment of one-way functions, pseudorandomness, and zero-knowledge proofs. It is suitable for use in a graduate course on cryptography and as a reference book for experts. The author assumes basic familiarity with the design and analysis of algorithms; some knowledge of complexity theory and probability is also useful.
