Written by a well-respected expert in number theory and cryptography, this book gives a self-contained introduction to areas of algebra, number theory and computer science which form the underlying basis for cryptography. The book leads readers into advanced methods, including material on cryptographic systems which have not previously appeared in book form.
This edition is atrocious; it could seriously use some proof-reading. It's hard to concentrate on the contents if there's an error on every page. It almost seems as if the translator didn't understand the text.
