Beware missing online resource access code.When you purchase this book if may be missing the online resource access code.This creates loads of hassle and I am still trying to gain access via a customer request to the publisher.Nightmare when you have enough to do, like studying and trying to absorb the content of the book not wasting time chasing access codes and waiting to access important notes, information with the Online companion resource.Why make life so complicated I guess the clue was in the book title Doohh

The first chapter will lure you in with its great formatting After that the book goes massively downhill, chapter 2 will leave you confused than you started with The problems at the end of the chapter don t even follow the structure of the chapter Some of them especially the ones related to modular math weren t put in the lowest terms which makes them look difficult than they are.All of this doesn t even begin to help when the author introduces an example it takes 2 3 examples to fully understand the first example Nested examples are about as wonderful as GOTO statements in Basic.This author needs an editor for the book that will make it easy to understand the principles and practice of cryptography and network security easy enough for a layperson to understand This book looks like it was just stamped through for publishing without any proof reading.It s a shame on Pearson and this Author to allow such a book to be published

Tema novedoso y de actualizar todo el tiempo, buen libro cumpli con las expectativas esperadas.

Good for school

Poorly written and confusing First chapter is good, but goes downhill after Not great for an online only class.

I had to read this for a class Thankfully my class didn t get into the math The bad part is that the math is everywhere, so you have to skip around It would be better to have four parts per chapter The reference design part, the in use part, the math part, and then the ways in which to attack the encryption.The author loves to create formulas Somewhere in the book it says something like The number of X is the average of A and B thus we have X A B 2 1.3 Thank you for telling me how to compute an average, because I didn t know the equationBut the problem is that the math then gets pretty intense, so unless you remember a lot of matrix math and binary octal math, then you need to refer to the appendix There is no medium it s too easy and then too hard.Ignoring the math Most of the book , the background information and theory are very helpful The author is incredibly smart, and probably had a tough time dumbing it down to us mere mortals.
