From the reviews: "This monograph gives an overview of cryptographic access control with an emphasis on key management. The authors compare different techniques described in the literature. ... The book does not only give a valuable overview of the current methods. The authors also give detailed practical analysis of the key management functions such as key assignment and replacement as well as re-keying in the different approaches." (Ulrich Tipp, Zentralblatt MATH, Vol. 1202, 2011) "Data encryption--the main technique used to control access to data--is the subject of this book. ... the intended audience comprises students, researchers, and teachers. ... The authors proceed by presenting an algorithm and an experimental measurement of its performance. ... The book has an extensive bibliography--151 entries--and a minimal index." (J. W. Snively, ACM Computing Reviews, February, 2012)
