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.
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.
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.
Over the past few decades, there has been numerous research studies conducted involving the synchronization of dynamical systems with several theoretical studies and laboratory experimentations demonstrating the pivotal role for this phenomenon in secure communications. Chaos Synchronization and Cryptography for Secure Communications: Applications for Encryption explores the combination of ordinary and time delayed systems and their applications in cryptographic encoding. This innovative publication presents a critical mass of the most sought after research, providing relevant theoretical frameworks and the latest empirical research findings in this area of study.
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.
This book provides a practical introduction to cryptographic principles and algorithms for communication security and data privacy--written by one of the world's leading authorities on encryption and coding.
The monograph begins with a systematic introduction of chaos and chaos synchronization, and then extends to the methodologies and technologies in secure communication system design and implementation. The author combines theoretical frameworks with empirical studies, making the book a pratical reference for both academics and industrial engineers.
This innovative resource provides comprehensive coverage of the policies, practices, and guidelines needed to address the security issues related to today's wireless sensor networks, satellite services, mobile e-services, and inter-system roaming and interconnecting systems. It details the major mobile standards for securing mobile communications and examines architectures that can provide data confidentiality, authentication, integrity, and privacy in various wireless environments. The book defines the roles and responsibilities that network operators, service providers, and even customers need to fulfill to assure mobile communications are as secure as they are prolific.
This fascinating book presents the timeless mathematical theory underpinning cryptosystems both old and new, written specifically with engineers in mind. Ideal for graduate students and researchers in engineering and computer science, and practitioners involved in the design of security systems for communications networks.
