Cryptography, in particular public-key cryptography, has emerged in the last 20 years as an important discipline that is not only the subject of an enormous amount of research, but provides the foundation for information security in many applications. Standards are emerging to meet the demands for cryptographic protection in most areas of data communications. Public-key cryptographic techniques are now in widespread use, especially in the financial services industry, in the public sector, and by individuals for their personal privacy, such as in electronic mail. This Handbook will serve as a valuable reference for the novice as well as for the expert who needs a wider scope of coverage within the area of cryptography. It is a necessary and timely guide for professionals who practice the art of cryptography. The Handbook of Applied Cryptography provides a treatment that is multifunctional: It serves as an introduction to the more practical aspects of both conventional and public-key cryptography It is a valuable source of the latest techniques and algorithms for the serious practitioner It provides an integrated treatment of the field, while still presenting each major topic as a self-contained unit It provides a mathematical treatment to accompany practical discussions It contains enough abstraction to be a valuable reference for theoreticians while containing enough detail to actually allow implementation of the algorithms discussed Now in its third printing, this is the definitive cryptography reference that the novice as well as experienced developers, designers, researchers, engineers, computer scientists, and mathematicians alike will use.

The 3rd International Conference on Applied Cryptography and Network Security (ACNS 2005) was sponsored and organized by ICISA (the International Commu- cations and Information Security Association). It was held at Columbia University in New York, USA, June 7–10, 2005. This conference proceedings volume contains papers presented in the academic/research track. ACNS covers a large number of research areas that have been gaining importance in recent years due to the development of the Internet, wireless communication and the increased global exposure of computing resources. The papers in this volume are representative of the state of the art in security and cryptography research, worldwide. The Program Committee of the conference received a total of 158 submissions from all over the world, of which 35 submissions were selected for presentation at the a- demic track. In addition to this track, the conference also hosted a technical/ industrial/ short papers track whose presentations were also carefully selected from among the submissions. All submissions were reviewed by experts in the relevant areas.

Beginning Cryptography with Java While cryptography can still be a controversial topic in the programming community, Java has weathered that storm and provides a rich set of APIs that allow you, the developer, to effectively include cryptography in applications-if you know how. This book teaches you how. Chapters one through five cover the architecture of the JCE and JCA, symmetric and asymmetric key encryption in Java, message authentication codes, and how to create Java implementations with the API provided by the Bouncy Castle ASN.1 packages, all with plenty of examples. Building on that foundation, the second half of the book takes you into higher-level topics, enabling you to create and implement secure Java applications and make use of standard protocols such as CMS, SSL, and S/MIME. What you will learn from this book How to understand and use JCE, JCA, and the JSSE for encryption and authentication The ways in which padding mechanisms work in ciphers and how to spot and fix typical errors An understanding of how authentication mechanisms are implemented in Java and why they are used Methods for describing cryptographic objects with ASN.1 How to create certificate revocation lists and use the Online Certificate Status Protocol (OCSP) Real-world Web solutions using Bouncy Castle APIs Who this book is for This book is for Java developers who want to use cryptography in their applications or to understand how cryptography is being used in Java applications. Knowledge of the Java language is necessary, but you need not be familiar with any of the APIs discussed. Wrox Beginning guides are crafted to make learning programming languages and technologies easier than you think, providing a structured, tutorial format that will guide you through all the techniques involved.

Information Systems (IS) are a nearly omnipresent aspect of the modern world, playing crucial roles in the fields of science and engineering, business and law, art and culture, politics and government, and many others. As such, identity theft and unauthorized access to these systems are serious concerns. Theory and Practice of Cryptography Solutions for Secure Information Systems explores current trends in IS security technologies, techniques, and concerns, primarily through the use of cryptographic tools to safeguard valuable information resources. This reference book serves the needs of professionals, academics, and students requiring dedicated information systems free from outside interference, as well as developers of secure IS applications. This book is part of the Advances in Information Security, Privacy, and Ethics series collection.

A while back I wrote two documents called 'Building a Cloud Service' and the 'Convergence Report'. They basically documented my past experiences and detailed some of the issues that a cloud company may face as it is being built and run. Based on what had transpired since, a lot of the concepts mentioned in that particular document are becoming widely adopted and/or are trending towards them. This is a continuation of that particular document and will attempt to analyse the issues that are faced as we move towards the cloud especially with regards to security. Once again, we will use past experience, research, as well as current events trends in order to write this particular report. Personal experience indicates that keeping track of everything and updating large scale documents is difficult and depending on the system you use extremely cumbersome. The other thing readers have to realise is that a lot of the time even if the writer wants to write the most detailed book ever written it’s quite simply not possible. Several of my past works (something such as this particular document takes a few weeks to a few months to write depending on how much spare time I have) were written in my spare time and between work and getting an education. If I had done a more complete job they would have taken years to write and by the time I had completed the work updates in the outer world would have meant that the work would have meant that at least some of the content would have been out of date. Dare I say it, by the time that I have completed this report itself some of the content may have come to fruition as was the case with many of the technologies with the other documents? I very much see this document as a starting point rather than a complete reference for those who are interested in technology security. Note that the information contained in this document is not considered to be correct nor the only way in which to do things. It’s a mere guide to how the way things are and how we can improve on them. Like my previous work, it should be considered a work in progress. Also, note that this document has gone through many revisions and drafts may have gone out over time. As such, there will be concepts that may have been picked up and adopted by some organisations while others may have simply broken cover while this document was being drafted and sent out for comment. It also has a more strategic/business slant when compared to the original document which was more technically orientated. No illicit activity (as far as I know and have researched) was conducted during the formulation of this particular document. All information was obtained only from publicly available resources and any information or concepts that are likely to be troubling has been redacted. Any relevant vulnerabilities or flaws that were found were reported to the relevant entities in question (months have passed). Feedback/credit on any ideas that are subsequently put into action based on the content of this document would be appreciated. Any feedback on the content of this document is welcome.

Please note that this is an organic document that will change as we learn more about this new computing paradigm.
