"Crypto" is part of the job description for network designers, network engineers, and telecom developers. If you need cryptography basics - but dread the thick tomes that are your only other option - help is at hand."Cryptography Demystified" puts the fundamentals into a 35-module, learn-by-doing package that's actually fun to use. You must read this book if: you prefer your simplifications from an expert who understands the complexities; 6 years of success as a short course for students and professionals works for you; you enjoy hearing the phrase "nothing to memorize"; ecommerce, email, network security, or wireless communications is part of your bailiwick; cracking cryptography means a jump up the career ladder; the words "public-key cryptography," "channel-based cryptography," and "prime numbers" pique your interest; and, best-practices cryptography is the only secure way for you - and your company - to go. One of the most complex subjects in Information Technology, cryptography gets its due in this down-to-earth, self-teaching tutorial - the first to make the basics of the science truly accessible.
