I have written the security chapter for a multi-author volume on ubiquitous computing that will be published by Springer later this year. For me it was an opportunity to pull together some of the material I have been collecting for a possible second edition of my 2002 book on Security for Ubiquitous Computing—but of course a 30-page chapter can be nothing more than a brief introduction.

Anyway, here is a “release candidate” copy of the chapter, which will ship to the book editors in a couple of weeks. Comments are welcome, either on the chapter itself or, based on this preview, on what you’d like me to discuss in my own full-length book when I yield to the repeated pleas of John Wiley And Sons and sit down to write a new edition.
