Secret History


Book Description

The first edition of this award-winning book attracted a wide audience. This second edition is both a joy to read and a useful classroom tool. Unlike traditional textbooks, it requires no mathematical prerequisites and can be read around the mathematics presented. If used as a textbook, the mathematics can be prioritized, with a book both students and instructors will enjoy reading. Secret History: The Story of Cryptology, Second Edition incorporates new material concerning various eras in the long history of cryptology. Much has happened concerning the political aspects of cryptology since the first edition appeared. The still unfolding story is updated here. The first edition of this book contained chapters devoted to the cracking of German and Japanese systems during World War II. Now the other side of this cipher war is also told, that is, how the United States was able to come up with systems that were never broken. The text is in two parts. Part I presents classic cryptology from ancient times through World War II. Part II examines modern computer cryptology. With numerous real-world examples and extensive references, the author skillfully balances the history with mathematical details, providing readers with a sound foundation in this dynamic field. FEATURES Presents a chronological development of key concepts Includes the Vigenère cipher, the one-time pad, transposition ciphers, Jefferson’s wheel cipher, Playfair cipher, ADFGX, matrix encryption, Enigma, Purple, and other classic methods Looks at the work of Claude Shannon, the origin of the National Security Agency, elliptic curve cryptography, the Data Encryption Standard, the Advanced Encryption Standard, public-key cryptography, and many other topics New chapters detail SIGABA and SIGSALY, successful systems used during World War II for text and speech, respectively Includes quantum cryptography and the impact of quantum computers







Transformations in Criminal Jurisdiction


Book Description

Can traditional approaches to criminal jurisdiction adapt to the new global reality of the digital era? In this innovative book, leading experts in criminal, international and internet law unite to address this fundamental question. They consider how jurisdictional regimes are orientated around concepts of territoriality and extraterritoriality, how these categories are increasingly blurred in the digital era, and how a range of jurisdictional transformations are occurring in the process. Part I presents novel doctrinal, empirical and theoretical perspectives on criminal jurisdiction, exploring how states are shaping and reimagining jurisdictional concepts in the crafting and interpretation of criminal offences, and the ramifications of increasing jurisdictional concurrency in state practice. Part II focuses on the investigative and enforcement powers of the state to assess how these issues are transforming traditional understandings of jurisdictional rules and boundaries, the challenges and opportunities that these present for law enforcement authorities, and the sorts of constraints and safeguards that may be necessary as a result. The picture that emerges is a world of jurisdictional rules in a state of flux, which demands the diversity of legal perspectives presented in this book for documenting, rationalising and moving beyond the transformations that are taking shape in modern statecraft.

Data Privacy During Pandemics


Book Description

As part of the response to the COVID-19 pandemic, governments worldwide have deployed mobile phone surveillance programs to augment public health interventions. However, these programs raise privacy concerns. The authors of this report examine whether two goals can be achieved concurrently: the use of mobile phones as public health surveillance tools to help manage COVID‐19 and future crises, and the protection of privacy and civil liberties.




Beyond Snowden


Book Description

Safeguarding Our Privacy and Our Values in an Age of Mass Surveillance America’s mass surveillance programs, once secret, can no longer be ignored. While Edward Snowden began the process in 2013 with his leaks of top secret documents, the Obama administration’s own reforms have also helped bring the National Security Agency and its programs of signals intelligence collection out of the shadows. The real question is: What should we do about mass surveillance? Timothy Edgar, a long-time civil liberties activist who worked inside the intelligence community for six years during the Bush and Obama administrations, believes that the NSA’s programs are profound threat to the privacy of everyone in the world. At the same time, he argues that mass surveillance programs can be made consistent with democratic values, if we make the hard choices needed to bring transparency, accountability, privacy, and human rights protections into complex programs of intelligence collection. Although the NSA and other agencies already comply with rules intended to prevent them from spying on Americans, Edgar argues that the rules—most of which date from the 1970s—are inadequate for this century. Reforms adopted during the Obama administration are a good first step but, in his view, do not go nearly far enough. Edgar argues that our communications today—and the national security threats we face—are both global and digital. In the twenty first century, the only way to protect our privacy as Americans is to do a better job of protecting everyone’s privacy. Beyond Surveillance: Privacy, Mass Surveillance, and the Struggle to Reform the NSA explains both why and how we can do this, without sacrificing the vital intelligence capabilities we need to keep ourselves and our allies safe. If we do, we set a positive example for other nations that must confront challenges like terrorism while preserving human rights. The United States already leads the world in mass surveillance. It can lead the world in mass surveillance reform.

Exploring Encryption and Potential Mechanisms for Authorized Government Access to Plaintext


Book Description

In June 2016 the National Academies of Sciences, Engineering, and Medicine convened the Workshop on Encryption and Mechanisms for Authorized Government Access to Plaintext. Participants at this workshop discussed potential encryption strategies that would enable access to plaintext information by law enforcement or national security agencies with appropriate authority. Although the focus of the workshop was on technical issues, there was some consideration of the broader policy context, and discussion about the topics of encryption and authorized exceptional analysis frequently addressed open policy questions as well as technical issues. This publication summarizes the presentations and discussions from the workshop.




U.S. Encryption Policy


Book Description




Listening in


Book Description

A cybersecurity expert and former Google privacy analyst's urgent call to protect devices and networks against malicious hackers​ New technologies have provided both incredible convenience and new threats. The same kinds of digital networks that allow you to hail a ride using your smartphone let power grid operators control a country's electricity--and these personal, corporate, and government systems are all vulnerable. In Ukraine, unknown hackers shut off electricity to nearly 230,000 people for six hours. North Korean hackers destroyed networks at Sony Pictures in retaliation for a film that mocked Kim Jong-un. And Russian cyberattackers leaked Democratic National Committee emails in an attempt to sway a U.S. presidential election. And yet despite such documented risks, government agencies, whose investigations and surveillance are stymied by encryption, push for a weakening of protections. In this accessible and riveting read, Susan Landau makes a compelling case for the need to secure our data, explaining how we must maintain cybersecurity in an insecure age.
