From the Author
E-commerce can take place between companies and customers (business-to-customer), between companies (business-to-business), or between customers/companies and public administration (e-government). A typical e-commerce transaction involves information about goods or services, offers, ordering, delivery and payment. Obviously, since these processes take place in a public and therefore untrusted network, there are many security issues involved, such as verification of the identities of the participants, or protection of data in transfer. Security issues in e-commerce applications can mostly be found in many other network applications as well. Some security requirements are, however, specific to e-commerce and demand specially tailored security concepts (e.g., electronic payment). The purpose of this book is to give an in-depth overview of all the basic security problems and solutions that can be relevant for an e-commerce application.

My main motivation for writing this book was to support my lecture on network and e-commerce security at the Technical University of Vienna. There are many useful works on individual aspects of e-commerce security such as cryptography, network or Web security, or electronic payment systems. Nevertheless, I wanted a book I could recommend to my students that would cover (and update) all topics that I considered relevant. It can be said that this book is the result of my eight years of experience teaching computer and network security at the graduate level. The book is also intended for all IT professionals and others with some technical background who are interested in e-commerce security.

The book has five parts. Each part can be read individually, but each builds upon the previous parts. For example, the basic security mechanisms are explained in Part 1, so they are not explained again when mentioned elsewhere. It is not necessary to study all the math in Part 1 to understand other parts of the book.
