Book Description

Dec 18 2000 Technology Briefs Series (Book 6)
A clear and easy guide on how to use cryptography to secure e-commerce transactions
To be on the cutting edge of e-commerce, you need to understand how to best utilize cryptography to offer secure services for your customers over the Internet. But if you reach for most of the available books on the subject, you'll find that they are far too technical for most business needs. If you need a quick and lucid managerial summary to help you develop effective e-commerce strategies, this is the book for you.
Geared to nontechnical managers who would like to explore the underlying concepts of modern cryptography, this book features an easily accessible, logical explanation of how cryptography works to solve real-world e-commerce problems, a tutorial on the underlying mathematics, and two case studies of PKI cryptographic architectures, showing how Kerberos and PKC can be wedded to protect a company's intranet and how a full-blown working PKI provides security to a company's Internet communications.
Divided into three major parts tailored to readers' needs-Introduction to Modern Cryptography, Tutorial on the Mathematics of Cryptography, and case studies-the book covers:
How symmetrical key cryptography ensures confidentiality of messages
How cryptography lets you detect whether a message has been modified in transit
Why the distribution of cryptographic keys is important and difficult
The nuts and bolts of Kerberos-a major component of Microsoft's Windows 2000 security solution
How Public Key Cryptography ensures security between people who share no prior secret information
Digital signatures on electronic contracts and the concept of non-repudiation
How digital certificates ensure positive identification of individuals

The goal of this book is to provide an introduction to the basic concepts of cryptography to non-technical people, and to illustrate how cryptography can be applied in e-commerce applications. The author has succeeded admirably in this endeavor.
The first part of the book provides a gentle introduction to symmetric-key encryption and authentication, public-key cryptography, key managements and PKI. The detailed explanations are accompanied with intuitive figures. For the most part, the mathematical intricacies are omitted from the main chapters thus enabling the reading to grasp the important concepts without getting bogged down with technical details. For those interested in the underlying mathematics, the second part of the book provides a tutorial to some of the mathematics. Finally, the third part of the book describes two crytographic architectures designed by the author.
I highly recommend this book to the people with nontechnical backgrounds who are interested in learning how cryptography can be used to secure their applications. Once the basic concepts are understood, the reader can then proceed to one of the many available technical books on cryptography.

5.0 out of 5 stars Now I Understand Cryptography!!! Feb. 12 2001

Format:Paperback
I also agree with the above reviewer. Cryptography and E-Commerce is a great introduction to the essentials of modern cryptography in today's eBusiness. The cryptography concepts are wonderfully illustrated, and the analogies are light-hearted and very easy to understand. It not only includes many real-world examples, it also shed some light on problems associated with cryptography (i.e. Key Management Problems), that companies face today. There is an easy-to-understand section on the mathematics behind public key cryptography that does not require a background on number theory, as well as 2 case studies that really fortified my understanding of the concepts introduced in the book. There's more to cryptography than just the mathematics. I appreciate the fact that the author took some time to explain the business case associated with implementing modern cryptography. I really enjoyed this book and learned a great deal. Definitely a must -have on the bookshelf.

Format:Paperback
The basics of the usage of symmetric and asymmetric cryptography are explained here step by step in a precise way visualized by clear drawings of a sender, (evil) observer and recipient. Starting with the simplest case and showing what's faulty about it, the author develops an understanding of why it needs message digestion, public and private keys and either Kerberos or a certification authority.
A small part of the book is reserved for some mathematical expostions which do not go very far. Two case studies, one awkward, one profound, round off the book.
The term e-commerce in the title is somewhat misleading. The book deals rather with B2B, the other subcategory of e-business.
A possible audience for the book are people like me, who are supposed to know what excatly a digital signature is and therfore cannot really ask someone.

5.0 out of 5 stars A book everyone needs to read Jan. 11 2001
By A Customer
Format:Paperback
I have just finished reading Jon's book regarding Cryptography and E-Commerce. This is one of the best explanations I have seen regarding these complex topics and issues. Mr. Graff presents them in a clear, concise, and humorous style. The book is full of pictures and figures which makes these concepts very easy to follow and understand. This book is a must read for anyone who wants to understand the basics of cryptography without plowing through dreary technical texts. Cryptography and E-Commerce should be included in every technical library and also in most non-technical libraries. Anyone who uses the Internet needs to know this information.
