Reference Books on Cryptography

I successfully ended the book Elementary Number Theory by David M. Burton. It is a great book on Number Theory and History of Number Theory. Specially, I loved the concise chapter on Cryptography. Now, I am pretty interested to continue my study in Cryptography. Which books or websites should I read to learn more on Cryptography, if there is more math of it?

Cryptography is a rapidly changing subject at its frontier. However, though it dates from 1997 the Handbook of Applied Cryptography by A. Menezes, P. van Oorschot, and S. Vanstone, has nice surveys of many topics related to cryptography.

Introduction to Modern Cryptography by J.Katz and Y.Lindell (CRC Press) is a nice book to start formal cryptography. For a more advanced reader, Foundations of Cryptography by Oded Goldreich can be handy.

I am reading Hoffstein, Pipher, Silverman-An Introduction to Mathematical Cryptography 2nd and also like from what I've read of Trappe, Washington-introduction to cryptography with coding theory 2nd. I have 85 books that I looked through briefly and these were the two best. The authors actually explain the theory intelligently because they actually understand the topics. The other books I looked at would explain things that were obvious (Paar, Pelzl) or hid the fact that they didn't understand everything by putting undefined meaningless symbols in a function.
