Appendix A. Security, Cryptography, and Protocol Background Material

This appendix is a collection of detailed reference information covering algorithms, protocols, and mathematics to support the core material in the book. We kept this detail out of the core chapters to make them easier to read but felt this material is useful for you to gain a deeper understanding of the protocols and algorithms used throughout Web Services Security. In particular, we believe an understanding of the computational complexity of these algorithms will lend a deeper appreciation of the way your deployed secure Web services applications will perform.
