The bible of cryptography, 7 Nov. 2013
I bought it for a university course of computer security and I'm very satisfied about it. It covers all the main topics of ancient and modern security mechanisms showing them first in a simple way and then in a more specific one. Besides, there are about ten online chapters that deepens these topics. The only topic that it doesn't expound is access control policy.
