Cracking DES: Secrets of Encryption Research, Wiretap Politics & Chip Design is a book that, for the first time, reveals full technical details on how researchers and data-recovery engineers can build a working DES Cracker. It includes design specifications and board schematics, as well as full source code for the custom chip, a chip simulator, and the software that drives the system. The U.S. government makes it illegal to publish these details on the Web, but they're printed here in a form that's easy to read and understand, legal to publish, and convenient for scanning into your computer. The Data Encryption Standard withstood the test of time for twenty years. Cracking DES: Secrets of Encryption Research, Wiretap Politics & Chip Design shows exactly how it was brought down. Every cryptographer, security designer, and student of cryptography policy should read this book to understand how the world changed as it fell.
