Cryptography An Introduction

Download or read book Cryptography: An Introduction written by V. V. I︠A︡shchenko and published by American Mathematical Soc.. This book was released on 2002 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learning about cryptography requires examining fundamental issues about information security. Questions abound, ranging from ``Whom are we protecting ourselves from?'' and ``How can we measure levels of security?'' to ``What are our opponent's capabilities?'' and ``What are their goals?'' Answering these questions requires an understanding of basic cryptography. This book, written by Russian cryptographers, explains those basics. Chapters are independent and can be read in any order. The introduction gives a general description of all the main notions of modern cryptography: a cipher, a key, security, an electronic digital signature, a cryptographic protocol, etc. Other chapters delve more deeply into this material. The final chapter presents problems and selected solutions from ``Cryptography Olympiads for (Russian) High School Students''. This is an English translation of a Russian textbook. It is suitable for advanced high school students and undergraduates studying information security. It is also appropriate for a general mathematical audience interested in cryptography. Also on cryptography and available from the AMS is Codebreakers: Arne Beurling and the Swedish Crypto Program during World War II, SWCRY.
