Review:
This book is a very readable introduction to the theory of numbers. The author manages to concentrate in a relatively short book and with a very clear and pleasant style the material necessary to understand the mathematics underneath the RSA cryptosystem. No previous knowledge of advanced mathematics is assumed. Perhaps not enough for mathematicians, but more than rewarding for the rest of us. It reminds me a bit of the style of M. Gardner. Books on mathematics can be very dull without the style of exposition of Mr. Coutinho. Highly recommended !
Review:
all about understanding RSA
The book revolves around RSA. The motivation for the book is that the reader wants to understand public/private key cryptography, where this is represented by the seminal RSA algorithm.
The author assumes little previous acquaintance with number theory on your part. He develops his arguments from this minimal background. So modular arithmetic is introduced, and thence such key ideas as groups, primality tests, Chinese Remainder Theorem and, finally, the RSA cryptosystem. Each chapter has a problem set of moderate difficulty.
A maths undergraduate at the sophomore level or higher should be able to benefit from the book.
