Book Synopsis End-to-End Encrypted Messaging by : Rolf Oppliger
Download or read book End-to-End Encrypted Messaging written by Rolf Oppliger and published by Artech House. This book was released on 2020-04-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Secure Messaging Scenarios with WebSphere MQ by : T.Rob Wyatt
Download or read book Secure Messaging Scenarios with WebSphere MQ written by T.Rob Wyatt and published by IBM Redbooks. This book was released on 2013-04-02 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The differences between well-designed security and poorly designed security are not always readily apparent. Poorly designed systems give the appearance of being secure but can over-authorize users or allow access to non-users in subtle ways. The problem is that poorly designed security gives a false sense of confidence. In some ways, it is better to knowingly have no security than to have inadequate security believing it to be stronger than it actually is. But how do you tell the difference? Although it is not rocket science, designing and implementing strong security requires strong foundational skills, some examples to build on, and the capacity to devise new solutions in response to novel challenges. This IBM® Redbooks® publication addresses itself to the first two of these requirements. This book is intended primarily for security specialists and IBM WebSphere® MQ administrators that are responsible for securing WebSphere MQ networks but other stakeholders should find the information useful as well. Chapters 1 through 6 provide a foundational background for WebSphere MQ security. These chapters take a holistic approach positioning WebSphere MQ in the context of a larger system of security controls including those of adjacent platforms' technologies as well as human processes. This approach seeks to eliminate the simplistic model of security as an island, replacing it instead with the model of security as an interconnected and living system. The intended audience for these chapters includes all stakeholders in the messaging system from architects and designers to developers and operations. Chapters 7 and 8 provide technical background to assist in preparing and configuring the scenarios and chapters 9 through 14 are the scenarios themselves. These chapters provide fully realized example configurations. One of the requirements for any scenario to be included was that it must first be successfully implemented in the team's lab environment. In addition, the advice provided is the cumulative result of years of participation in the online community by the authors and reflect real-world practices adapted for the latest security features in WebSphere MQ V7.1 and WebSphere MQ V7.5. Although these chapters are written with WebSphere MQ administrators in mind, developers, project leaders, operations staff, and architects are all stakeholders who will find the configurations and topologies described here useful. The third requirement mentioned in the opening paragraph was the capacity to devise new solutions in response to novel challenges. The only constant in the security field is that the technology is always changing. Although this book provides some configurations in a checklist format, these should be considered a snapshot at a point in time. It will be up to you as the security designer and implementor to stay current with security news for the products you work with and integrate fixes, patches, or new solutions as the state of the art evolves.

Book Synopsis Decrypting the Encryption Debate by : National Academies of Sciences, Engineering, and Medicine
Download or read book Decrypting the Encryption Debate written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-06-07 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encryption protects information stored on smartphones, laptops, and other devices - in some cases by default. Encrypted communications are provided by widely used computing devices and services - such as smartphones, laptops, and messaging applications - that are used by hundreds of millions of users. Individuals, organizations, and governments rely on encryption to counter threats from a wide range of actors, including unsophisticated and sophisticated criminals, foreign intelligence agencies, and repressive governments. Encryption on its own does not solve the challenge of providing effective security for data and systems, but it is an important tool. At the same time, encryption is relied on by criminals to avoid investigation and prosecution, including criminals who may unknowingly benefit from default settings as well as those who deliberately use encryption. Thus, encryption complicates law enforcement and intelligence investigations. When communications are encrypted "end-to-end," intercepted messages cannot be understood. When a smartphone is locked and encrypted, the contents cannot be read if the phone is seized by investigators. Decrypting the Encryption Debate reviews how encryption is used, including its applications to cybersecurity; its role in protecting privacy and civil liberties; the needs of law enforcement and the intelligence community for information; technical and policy options for accessing plaintext; and the international landscape. This book describes the context in which decisions about providing authorized government agencies access to the plaintext version of encrypted information would be made and identifies and characterizes possible mechanisms and alternative means of obtaining information.

Download or read book Unfree Speech written by Joshua Wong and published by Penguin. This book was released on 2020-02-18 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: An urgent manifesto for global democracy from Joshua Wong, the 23-year-old phenomenon leading Hong Kong's protests - and Nobel Peace Prize nominee - with an introduction by Ai Weiwei With global democracy under threat, we must act together to defend out rights: now. When he was 14, Joshua Wong made history. While the adults stayed silent, Joshua staged the first-ever student protest in Hong Kong to oppose National Education -- and won. Since then, Joshua has led the Umbrella Movement, founded a political party, and rallied the international community around the anti-extradition bill protests, which have seen 2 million people -- more than a quarter of the population -- take to Hong Kong's streets. His actions have sparked worldwide attention, earned him a Nobel Peace Prize nomination, and landed him in jail twice. Composed in three parts, Unfree Speech chronicles Joshua's path to activism, collects the letters he wrote as a political prisoner under the Chinese state, and closes with a powerful and urgent call for all of us globally to defend our democratic values. When we stay silent, no one is safe. When we free our speech, our voice becomes one.
