## Cryptography: Theory and Practice, Third EditionTHE LEGACY... First introduced in 1995, Cryptography: Theory and Practice garnered enormous praise and popularity, and soon became the standard textbook for cryptography courses around the world. The second edition was equally embraced, and enjoys status as a perennial bestseller. Now in its third edition, this authoritative text continues to provide a solid foundation for future breakthroughs in cryptography. WHY A THIRD EDITION? The art and science of cryptography has been evolving for thousands of years. Now, with unprecedented amounts of information circling the globe, we must be prepared to face new threats and employ new encryption schemes on an ongoing basis. This edition updates relevant chapters with the latest advances and includes seven additional chapters covering: THE RESULT... Providing mathematical background in a "just-in-time" fashion, informal descriptions of cryptosystems along with more precise pseudocode, and a host of numerical examples and exercises, Cryptography: Theory and Practice, Third Edition offers comprehensive, in-depth treatment of the methods and protocols that are vital to safeguarding the mind-boggling amount of information circulating around the world. |

### What people are saying - Write a review

This is the hardest test book I have ever read on earth as an engineering student. The book is progressed with mathematical proof without suitable explanation and introduction. The exercise problems are especially merciless. The lack of sample problems even increases the pain. However, for anyone who want to build a solid mathematical understanding of cryptography. Go for this, and don't forget to refer to some other more intuitive material on the subject if need help.

This book is pathetic. For all the knowledge it may contain it is useless at delivering it to anyone who doesn't already understand the material. This piece of garbage is nothing more than a reference source for someone who already has a solid understanding of Cryptography and Number Theory concepts.
