The Twofish Encryption Algorithm: A 128-Bit Block Cipher

By John Kelsey, Doug Whiting, David Wagner, et al.

Book Overview

The first and only guide to one of today's most important new cryptography algorithms The Twofish Encryption Algorithm A symmetric block cipher that accepts keys of any length, up to 256 bits, Twofish is among the new encryption algorithms being considered by the National Institute of Science and Technology (NIST) as a replacement for the DES algorithm. Highly secure and flexible, Twofish works extremely well with large microprocessors, 8-bit smart card microprocessors, and dedicated hardware. Now from the team who developed Twofish, this book provides you with your first detailed look at: * All aspects of Twofish's design and anatomy * Twofish performance and testing results * Step-by-step instructions on how to use it in your systems * Complete source code, in C, for implementing Twofish On the companion Web site you'll find: * A direct link to Counterpane Systems for updates on Twofish * A link to the National Institute of Science and Technology (NIST) for ongoing information about the competing technologies being considered for the Advanced Encryption Standard (AES) for the next millennium For updates on Twofish and the AES process, visit these sites: * www.wiley.com/compbooks/schneier * www.counterpane.com * www.nist.gov/aes Wiley Computer Publishing Timely.Practical.Reliable Visit our Web site at www.wiley.com/compbooks/ Visit the companion Web site at www.wiley.com/compbooks/schneier

fascinating to a limited audience

Bruce Schneier is the Yoda of crpytography and information security, if you've heard him there's no need to ask anyone else. This book would probably only appeal to the genuinely avid crypto fan, its Greek to anyone else. It is a thorough exposition of the making of the Twofish cypher, the latest attempt to secure information as absolutely as possible. You must be well versed in cryptography to get anything out of the work...

A important book to decipher

This book is not a how-to-do thing. You will learn why this cypher was created, how it was created it all the details. Not an introductory book. But very worth to who ever want to enter modern applied cryptographic field.

Official Discription by the people that developed it.

This is the official discription of the Twofish encryption algorithm by the people that developed it. The book gives the direct discription of what they have done, *PLUS* the reasons behind the choices that they made, and the considerations that were involved. The book has a readable style, and covers this algorithm in greater detail than I've ever seen one covered before. This book is a must for anyone planning to implement...
