Prerequisites for

XML Security
Dournaee, Blake. 2002. 379 pages.
Categories: Applications and Protocols
An excellent book that covers XML digital signatures, XML encryption, and XML Key Management (XKMS), all in exacting detail. This book was first to press on these topics, so expect other books to be more timely as areas like XKMS evolve. Includes a shameless plug for RSA's BSAFE Cert-J, but thankfully it feels more like information and less like a commercial.
It seems that digital signatures and XML is sometimes an awkward marriage. Digital signatures are notoriously inflexible, because they exist, in part, to flag changes. In contrast, XML has many ways of expressing the same thing, and likes to work independent of varying platforms, encoding schemes, etc. This book addresses these issues by introducing the trusted transformations used to canonicalize the XML to make its expressiveness more deterministic prior to signing.
