I helped co-author a chapter in a book on hardware security that is listed below. A few universities are using it as a textbook in senior-level or graduate-level classes related to hardware security. If you are interested in a particular chapter, you can purchase online access to an individual chapter.
Introduction to Hardware Security and Trust, Mohammad Tehranipoor and Cliff Wang, Eds. New York: Springer, 2012. ISBN 978-1-4419-8079-3 or e-ISBN 978-1-4419-8080-9. Website
