Title: Highly Excellent, highly technical. Need Math Background.
Review: A very good book that describes every possible aspect of cryptography from square one to Russian ciphers. Very clear and technical, a plus o me but a minnus to others. Be sure you are intrested in this topic and have a good mathematical/computer background before buying this book. If so, this is one of the greatest books you'll ever buy. It's in my top 10 in my library.
