This exciting resource introduces the core technologies that are used for Internet messaging. The book explains how Signal protocol, the cryptographic protocol that currently dominates the field of end to end encryption (E2EE) messaging, is implemented and addresses privacy issues related to E2EE messengers. The Signal protocol and its application in WhatsApp is explored in depth, as well as the different E2EE messengers that have been made available in the last decade are also presented, including SnapChat. It addresses the notion of self-destructing messages (as originally introduced by SnapChat) and the use of metadata to perform traffic analysis. A comprehensive treatment of the underpinnings of E2EE messengers, including Pretty Good Privacy (PGP) and OpenPGP as well as Secure/Multipurpose Internet Mail Extensions (S/MIME) is given to explain the roots and origins of secure messaging, as well as the evolutionary improvements to PGP/OpenPGP and S/MIME that have been proposed in the past. In addition to the conventional approaches to secure messaging, it explains the modern approaches messengers like Signal are based on. The book helps technical professionals to understand secure and E2EE messaging on the Internet, and to put the different approaches and solutions into perspective.

The mobile industry for wireless cellular services has grown at a rapid pace over the past decade. Similarly, Internet service technology has also made dramatic growth through the World Wide Web with a wire line infrastructure. Realization for complete wired/wireless mobile Internet technologies will become the future objectives for convergence of these technologies through multiple enhancements of both cellular mobile systems and Internet interoperability. Flawless integration between these two wired/wireless networks will enable subscribers to not only roam worldwide, but also to solve the ever increasing demand for data/Internet services. In order to keep up with this noteworthy growth in the demand for wireless broadband, new technologies and structural architectures are needed to greatly improve system performance and network scalability while significantly reducing the cost of equipment and deployment. Dr. Rhee covers the technological development of wired/wireless internet communications in compliance with each iterative generation up to 4G systems, with emphasis on wireless security aspects. By progressing in a systematic matter, presenting the theory and practice of wired/wireless mobile technologies along with various security problems, readers will gain an intimate sense of how mobile internet systems operate and how to address complex security issues. Features: Written by a top expert in information security Gives a clear understanding of wired/wireless mobile internet technologies Presents complete coverage of various cryptographic protocols and specifications needed for 3GPP: AES, KASUMI, Public-key and Elliptic curve cryptography Forecast new features and promising 4G packet-switched wireless internet technologies for voice and data communications Provides MIMO/OFDMA-based for 4G systems such as Long Term Evolution (LTE), Ultra Mobile Broadband (UMB), Mobile WiMax or Wireless Broadband (WiBro) Deals with Intrusion Detection System against worm/virus cyber attacks The book ideal for advanced undergraduate and postgraduate students enrolled in courses such as Wireless Access Networking, Mobile Internet Radio Communications. Practicing engineers in industry and research scientists can use the book as a reference to get reacquainted with mobile radio fundamentals or to gain deeper understanding of complex security issues.

The first full-length book on the provocative subject of e-mail privacy, E-Mail Security takes a hard look at issues of privacy in e-mail, rates the security of the most popular e-mail programs, and offers practical solutions in the form of today's two leading-edge encryption programs, PEM and PGP.

This pioneering guide to Internet and intranet security is the first to cover all of the relevant technologies in one comprehensive reference, and enhances the ability to create and deploy secure architectures. It gives users the knowledge needed for improved productivity, whether setting up commerce on line, assembling a firewall, or selecting access controls and cryptographic protocols to secure TCP/IP-based networks.

Pretty Good Privacy, or "PGP", is an encryption program widely available on the Internet. The program runs on MS-DOS, UNIX, and the Mac. PGP: Pretty Good Privacy offers both a readable technical user's guide and a fascinating behind-the-scenes look at cryptography and privacy, explaining how to get PGP from publicly available sources and how to install it on various platforms.
