Invitation to Cryptology

The book was as described. As with the title, good-quality book, fast delivery, A++ service.

It's written in such a manner that someone with no cryptology knowledge can pick up and follow the text, and continue through smooth progressive chapters. I have only two years of my EE degree done, but i think anyone who can do arithmetic and has an interest in cryptology can read this book like a novel and take a good portion of it all with only reading and excercising with your brain. I read it and did all the exercises as well absolutely independently. I feel i have a solid grasp of all its content.
