Despite its reputation as a language only of spies and hackers, cryptography plays a critical role in our everyday lives. Though often invisible, it underpins the security of our mobile phone calls, credit card payments, web searches, internet messaging, and cryptocurrencies--in short, everything we do online. Increasingly, it also runs in the background of our smart refrigerators, thermostats, electronic car keys, and even the cars themselves. As our daily devices get smarter, cyberspace--home to all the networks that connect them--grows.

Broadly defined as a set of tools for establishing security in this expanding cyberspace, cryptography enables us to protect and share our information. Understanding the basics of cryptography is the key to recognizing the significance of the security technologies we encounter every day, which will then help us respond to them.

What are the implications of connecting to an unprotected Wi-Fi network? Is it really so important to have different passwords for different accounts? Is it safe to submit sensitive personal information to a given app, or to convert money to bitcoin? In clear, concise writing, information security expert Keith Martin answers all these questions and more, revealing the many crucial ways we all depend on cryptographic technology. He demystifies its controversial applications and the nuances behind alarming headlines about data breaches at banks, credit bureaus, and online retailers. We learn, for example, how encryption can hamper criminal investigations and obstruct national security efforts, and how increasingly frequent ransomware attacks put personal information at risk. Yet we also learn why responding to these threats by restricting the use of cryptography can itself be problematic.

Essential reading for anyone with a password, Cryptography offers a profound perspective on personal security, online and off.

This volume contains four articles written by personnel of the National Security Agency (NSA) about the Voynich manuscript from 1965 to 1978.

The first essay, by Brigadier John Tiltman, is entitled The Voynich Manuscript: The Most Mysterious Manuscript in the World and was presented to the Baltimore Bibliophiles in 1967. It provides a basic summary of facts about the manuscript and its provenance and adds a survey of proposed solutions, most of which it dispenses with quite quickly. I found it interesting to discover that Tiltman was first introduced to the Voynich ms. by William Friedman, founder of the NSA, in 1947 ( ) I was also intrigued that Tiltman's scholarly research into the history of medieval herbalism included consultations with leading English academics, no doubt during visits on Five Eyes business.

The second essay, originally classifed Top Secret Umbra, is An Application of PTAH to the Voynich Manuscript by Mary D'Imperio - the title itself was unclassified. A few pages in, I came to a full stop when I encountered this:

PTAH (named for the Egyptian god of wisdom), is a general statistical method developed at IDA (Institute for Defense Analyses), Princeton University. PTAH got its name when a programmer. Mr.Gerry Mitchell, was listening to the opera Aida while working on his program. He was struck by the passage immenso Ptah noi invociam, and named his program after the Egyptian god. The name was ultimately extended from this program, implementing a particular application of the method, to the method and its mathematical theory as well...

The technical meaning of PTAH remains classified, although Google helped me find a journal article that suggests PTAH must be some sort of Hidden Markov Model. (Math. Comput. Appl. 2019, 24, 14; doi:10.3390/mca24010014)

D'Imperio used PTAH to analyze the Voynich manuscript and similar works and concluded that I find the above comparisions quite convincing support for a view that the Voynich text, regarded as a string of single letters, does not 'act like' natural language. Instead, it exhibits a clear positional regularity or characters within words. I believe that these findings strengthen the theory of Friedman and Tiltman that an artificial language may underlie the Yoynich text.

Government interest dating back to 1947 ... pharmacology unknown to modern man ... artificial languages ... the movie ARRIVAL based on Ted Chiang's Story of Your Life ... hmmm ...

The third essay, also by D'Imperio, is An Application of Cluster Analysis and Multidimensional Scaling to the Question of 'Hands' and 'Languages' in the Voynich Manuscript. She uses cluster analytic techniques to examine findings by Captain Prescott Currier, who suggested that the manuscript's pages can be clustered into groups of multiple authors and styles. D'Imperio's discussion includes warnings that are still sound today: The interpretation of cluster analysis results is unavoidably circular; we propose a certain structure in the group of objects under study, we perform the computation, and we are happy if we see what we expected, or at least something that makes sense in terms of our original hypothesis, however revised.

The fourth and final essay, by James Child, takes an important step forward by proposing that the Voynich Manuscript does not contain an artificial language nor the enciphered text of an underlying text in an unknown language. but is a text in a hitherto unknown medieval North Germanic dialect.

People who enjoy works like THE DA VINCI CODE, PUZZLE PALACE, and Snowden will find this fascinating.

Views differ on bitcoin, but few doubt the transformative potential of Blockchain technology. The Truth Machine is the best book so far on what has happened and what may come along. It demands the attention of anyone concerned with our economic future. --Lawrence H. Summers, Charles W. Eliot University Professor and President Emeritus at Harvard, Former Treasury Secretary

From Michael J. Casey and Paul Vigna, the authors of The Age of Cryptocurrency, comes the definitive work on the Internet's Next Big Thing: The Blockchain.

Big banks have grown bigger and more entrenched. Privacy exists only until the next hack. Credit card fraud is a fact of life. Many of the legacy systems once designed to make our lives easier and our economy more efficient are no longer up to the task. Yet there is a way past all this--a new kind of operating system with the potential to revolutionize vast swaths of our economy: the blockchain.

In The Truth Machine, Michael J. Casey and Paul Vigna demystify the blockchain and explain why it can restore personal control over our data, assets, and identities; grant billions of excluded people access to the global economy; and shift the balance of power to revive society's faith in itself. They reveal the disruption it promises for industries including finance, tech, legal, and shipping.

Casey and Vigna expose the challenge of replacing trusted (and not-so-trusted) institutions on which we've relied for centuries with a radical model that bypasses them. The Truth Machine reveals the empowerment possible when self-interested middlemen give way to the transparency of the blockchain, while highlighting the job losses, assertion of special interests, and threat to social cohesion that will accompany this shift. With the same balanced perspective they brought to The Age of Cryptocurrency, Casey and Vigna show why we all must care about the path that blockchain technology takes--moving humanity forward, not backward.
