Hardy would have been surprised and probably displeased with the increasing interest in number theory for application to "ordinary human activities" such as information transmission error-correcting codes and cryptography secret codes.

This is a substantially revised and updated introduction to arithmetic topics, both ancient and modern, that have been at the centre of interest in applications of number theory, particularly in cryptography.

As such, no background in algebra or number theory is assumed, and the book begins with a discussion of the basic number theory that is needed. The approach taken is algorithmic, emphasising estimates of the efficiency of the techniques that arise from the theory, and one special feature is the inclusion of recent applications of the theory of elliptic curves. Extensive exercises and careful answers are an integral part all of the chapters. Read more Read less. Frequently bought together.

I won't be sharing too many textbooks but this one needs attention. Written by Neal Koblitz, one of my favorite mathematicians and the inventor of elliptic curve cryptography.

I love two of his books. I'll keep the other book secret until the next part of the series. I love Neal's book because he gets straight to the point and uses a smaller font in his books to pack more information on one page.

This is one of the first books I ever read on mathematical foundations of cryptography. It says graduate on the cover but don't listen to that. It's really an undergraduate level book. All you need to know is a bit of algebra. Book starts with a review of several key number theory topics, moves to finite fields, then to the public key cryptography, RSA, zero-knowledge proofs, then primality testing, factoring and finally elliptic curves.

This book follows definition-theorem-proof-example style that I like and it has many exercises with answers. If you like math but don't have experience with fundamentals of cryptography then this is the book to get to quickly get yourself up to speed. Fundamentals don't change and once you master what's in this book shouldn't take more than a week or two if you're smart and dedicated , you'll be able to read any crypto text. I've placed this book 17 in my Top Programming, Computer and Science books list: [ But I was surprised to find the topic not as daunting as I thought although people who lock up when they see formulas may be intimidated at first glance.

This book deals with number theory, dealing with some fundamental properties of numbers with application to cryptographic uses.

Each section takes you slowly through the theory and provides exercises at the end of each chapter you can work through. The answers are in the back of the book.

This is a particularly useful book if you are conversant in programming and want to play with certain aspects of number theory and cryptography to 'see how it really works. Very useful for understanding cryptography. This is a great read on the topic from a mathematical perspective.

Still, if you believe that cryptography is the only point of this book, you're doing it wrong. The item is in great conditions! Go to Amazon. Back to top. Get to Know Us. Shopbop Designer Fashion Brands. Alexa Actionable Analytics for the Web. DPReview Digital Photography.
