Book Description
Bücher über Kryptologie, die Algorithmen und Verschlüsselungstechniken beschreiben, gibt es in Hülle und Fülle. Aber es gibt nur wenige Bücher, die sich - wie "Secure Communications" - mit der praktischen Seite der sicheren Sprachübertragung beschäftigen. Autor Roger Sutton diskutiert hier verschiedene Kommunikationsmedien, wobei er insbesondere auf technische Fragen und Sicherheitsrisiken eingeht und verschiedene Möglichkeiten zur Problemlösung aufgezeigt. Zahlreiche durchgearbeitete Beispiele für Netzwerke runden den Text ab.

Book Description
Secure message transmission is of extreme importance in today's information-based society: military, diplomatic, and corporate data transmissions must be safeguarded; so also must the account of every individual who has an automatic-teller bank account or whose purchases are subject to point-of-sale, direct account debiting. The only known way to keep all such transactions secret and authentic is by way of cryptographic techniques. But most cryptosystems in use today are not fool-proof-- their "symmetric" nature allows them to be compromised if either the sender's or the receiver's "key" (decoding algorithm) falls into the wrong hands. This book reports on the enormous amount of work that has been done in the past on the concept, "asymmetric" cryptography.

Book Description
The mid-infrared domain is a promising optical domain because it holds two transparency atmospheric windows, as well as the fingerprint of many chemical compounds. Quantum cascade lasers (QCLs) are one of the available sources in this domain and have already been proven useful for spectroscopic applications and free-space communications. This thesis demonstrates how to implement a private free-space communication relying on mid-infrared optical chaos and this requires an accurate cartography of non-linear phenomena in quantum cascade lasers. This private transmission is made possible by the chaos synchronization of two twin QCLs. Chaos in QCLs can be generated under optical injection or external optical feedback. Depending on the parameters of the optical feedback, QCLs can exhibit several non-linear phenomena in addition to chaos. Similarities exist between QCLs and laser diodes when the chaotic dropouts are synchronized with an external modulation, and this effect is known as the entrainment phenomenon. With a cross-polarization reinjection technique, QCLs can generate all-optical square-waves. Eventually, it is possible to trigger optical extreme events in QCLs with tilted optical feedback. All these experimental results allow a better understanding of the non-linear dynamics of QCLs and will extend the potential applications of this kind of semiconductor lasers.

Book Description
This book provides a first course on lattices – mathematical objects pertaining to the realm of discrete geometry, which are of interest to mathematicians for their structure and, at the same time, are used by electrical and computer engineers working on coding theory and cryptography. The book presents both fundamental concepts and a wealth of applications, including coding and transmission over Gaussian channels, techniques for obtaining lattices from finite prime fields and quadratic fields, constructions of spherical codes, and hard lattice problems used in cryptography. The topics selected are covered in a level of detail not usually found in reference books. As the range of applications of lattices continues to grow, this work will appeal to mathematicians, electrical and computer engineers, and graduate or advanced undergraduate in these fields.

Book Description
Hearing on the various types of security risks to communications systems, such as privacy, computer hackers & electronic commerce, encryption, corporate espionage, espionage by terrorists or foreign enemies, & security of telephone lines, particularly security of cellular transmissions. One area of major concern that receives virtually no publicity but which is very important, particularly in the world of commerce & government, is the authenticity of the messages being transmitted.

Book Description
Most applications these days are at least somewhat network aware, but how do you protect those applications against common network security threats? Many developers are turning to OpenSSL, an open source version of SSL/TLS, which is the most widely used protocol for secure network communications.The OpenSSL library is seeing widespread adoption for web sites that require cryptographic functions to protect a broad range of sensitive information, such as credit card numbers and other financial transactions. The library is the only free, full-featured SSL implementation for C and C++, and it can be used programmatically or from the command line to secure most TCP-based network protocols.Network Security with OpenSSL enables developers to use this protocol much more effectively. Traditionally, getting something simple done in OpenSSL could easily take weeks. This concise book gives you the guidance you need to avoid pitfalls, while allowing you to take advantage of the library?s advanced features. And, instead of bogging you down in the technical details of how SSL works under the hood, this book provides only the information that is necessary to use OpenSSL safely and effectively. In step-by-step fashion, the book details the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges.As a system or network administrator, you will benefit from the thorough treatment of the OpenSSL command-line interface, as well as from step-by-step directions for obtaining certificates and setting up your own certification authority. As a developer, you will further benefit from the in-depth discussions and examples of how to use OpenSSL in your own programs. Although OpenSSL is written in C, information on how to use OpenSSL with Perl, Python and PHP is also included.OpenSSL may well answer your need to protect sensitive data. If that?s the case, Network Security with OpenSSL is the only guide available on the subject.
