Publisher's Note: Products purchased from Third Party sellers are not guaranteed by the publisher for quality, authenticity, or access to any online entitlements included with the product. AN UNCONVENTIONAL, FUN WAY TO MASTER THE BASICS OF CRYPTOGRAPHY Cryptography is not just for specialists. Now every wireless message, wireless phone call, online transaction, and email is encrypted at one end and decrypted at the other. "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 * 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.
