Book Description
Disappearing Cryptography, Second Edition describes how to take words, sounds, or images and hide them in digital data so they look like other words, sounds, or images. When used properly, this powerful technique makes it almost impossible to trace the author and the recipient of a message. Conversations can be submerged in the flow of information through the Internet so that no one can know if a conversation exists at all.This full revision of the best-selling first edition describes a number of different techniques to hide information. These include encryption, making data incomprehensible; steganography, embedding information into video, audio, or graphics files; watermarking, hiding data in the noise of image or sound files; mimicry, "dressing up" data and making it appear to be other data, and more. The second edition also includes an expanded discussion on hiding information with spread-spectrum algorithms, shuffling tricks, and synthetic worlds. Each chapter is divided into sections, first providing an introduction and high-level summary for those who want to understand the concepts without wading through technical explanations, and then presenting greater detail for those who want to write their own programs. To encourage exploration, the author's Web site www.wayner.org/books/discrypt2/ contains implementations for hiding information in lists, sentences, and images. - Each chapter is divided into sections, providing first an introduction and high-level summary for those who want to understand the concepts without wading through technical details, and then an introductory set of details, for those who want to write their own programs. - Fully revised and expanded. - Covers key concepts for non-technical readers. - Goes into technical details for those wanting to create their own programs and implement algorithms.

Book Description
Cryptography is a vital technology that underpins the security of information in computer networks. This book presents a comprehensive introduction to the role that cryptography plays in providing information security for technologies such as the Internet, mobile phones, payment cards, and wireless local area networks. Focusing on the fundamental principles that ground modern cryptography as they arise in modern applications, it avoids both an over-reliance on transient current technologies and over-whelming theoretical research. Everyday Cryptography is a self-contained and widely accessible introductory text. Almost no prior knowledge of mathematics is required since the book deliberately avoids the details of the mathematical techniques underpinning cryptographic mechanisms, though a short appendix is included for those looking for a deeper appreciation of some of the concepts involved. By the end of this book, the reader will not only be able to understand the practical issues concerned with the deployment of cryptographic mechanisms, including the management of cryptographic keys, but will also be able to interpret future developments in this fascinating and increasingly important area of technology.

Book Description
This exciting new resource provides a comprehensive overview of the field of cryptography and the current state of the art. It delivers an overview about cryptography as a field of study and the various unkeyed, secret key, and public key cryptosystems that are available, and it then delves more deeply into the technical details of the systems. It introduces, discusses, and puts into perspective the cryptographic technologies and techniques, mechanisms, and systems that are available today. Random generators and random functions are discussed, as well as one-way functions and cryptography hash functions. Pseudorandom generators and their functions are presented and described. Symmetric encryption is explored, and message authentical and authenticated encryption are introduced. Readers are given overview of discrete mathematics, probability theory and complexity theory. Key establishment is explained. Asymmetric encryption and digital signatures are also identified. Written by an expert in the field, this book provides ideas and concepts that are beneficial to novice as well as experienced practitioners.

Book Description
This book constitutes the thoroughly refereed post-workshop proceedings of the 18th International Workshop on Security Protocols, held in Cambridge, UK, in March 2010. After an introduction the volume presents 16 revised papers and one abstract, each followed by a revised transcript of the discussion ensuing the presentation at the event. The theme of this year's workshop was "Virtually Perfect Security".

Book Description
As the internet of things market is booming, several issues are delaying the full realization of the technology. Currently, business competitors are jockeying for a piece of the market, meaning solutions from researchers that address these issues is crucial for internet of things technology developers. Overpromising followed by underdelivering has been the current approach by many innovators, and the mismatch results in losses in production, orphaned technologies, and frequent system failures. Solutions that address internet of things performance issues must be studied in order to take full advantage of this emerging market. Achieving Full Realization and Mitigating the Challenges of the Internet of Things addresses the challenges faced in rolling out internet of things technologies as well as the various performance issues. Covering a range of topics such as cybersecurity and connectivity issues, this reference work is ideal for industry professionals, academicians, researchers, practitioners, technology developers, instructors, and students.
