Cryptography & Network Security (McGraw-Hill Forouzan Networking) Review

Average Reviews:

(More customer reviews)I teach an introductory cryptography class at the University of Denver. I have been seeking a good text for six years, but I have been disappointed with all that I have tried. Forouzan's book is the answer to my dreams.
It is neither over-simplified nor overly rigorous. Theorem proofs are saved for an appendix, so students don't get bogged down in the math before they have had a chance to assimilate the cryptographic concepts. Copious illustrations help with the most complex topics. Practice problems provide an opportunity for students to test their mastery and for the instructor to measure their progress.
The primary focus of the text is network security - specifically, e-mail, SSL and IPsec. (Esoteric protocols such as secure elections and digital cash are not discussed at all.) This text, in essence, is an elaboration of the final part of Forouzan's TCP/IP text. As such, it is extremely useful to those who are looking for skills that are immediately applicable to the work environment.

A textbook for beginners in security.In this new first edition, well-known author Behrouz Forouzan uses his accessible writing style and visual approach to simplify the difficult concepts of cryptography and network security. This edition also provides a website that includes Powerpoint files as well as instructor and students solutions manuals.Forouzan presents difficult security topics from the ground up.A gentle introduction to the fundamentals of number theory is provided in the opening chapters, paving the way for the student to move on to more complex security and cryptography topics.Difficult math concepts are organized in appendices at the end of each chapter so that students can first learn the principles, then apply the technical background.Hundreds of examples, as well as fully coded programs, round out a practical, hands-on approach which encourages students to test the material they are learning.
