The most recommended cryptography books

Any research into the codebreaking arm of British Intelligence during the Great War will quickly point to one man as the mastermind: Admiral Sir Reginald “Blinker” Hall. He is, at a glance, one of the most intriguing historical figures you’ll ever come across…and the more you learn, the more convinced you’ll be of that. In Blinker Hall, Spymaster, Ramsay delivers not only a thorough look into intelligence and codebreaking, using documents that have been declassified only recently to his writing, but also an insightful look into the man who orchestrated one of the most complex intelligence systems of the modern era. For anyone interested in intelligence, cryptography, or even just the invisible world behind a war that spanned continents, this book delivers it all, and does it in an engaging, entertaining style.

Although David is a friend, I only recommend his book because it’s great, both in terms of content and presentation. Real-World Cryptography is today’s reference book about cryptographic tools and applications: Modern schemes such as the SHA-3 hash function and the Noise protocol framework, end-to-end encryption protocols, cryptocurrencies’ cryptography mechanisms, as well as emerging techniques like fully-homomorphic encryption and multi-party computation; Wong’s book delivers a practice-oriented, accessible introduction, enriched by many visual illustrations (including original comics strips!), and exercises (with their solutions). 

This book makes me jealous as the author has an incredible ability to communicate the densest of topics (Cryptography) in an engaging, wonderful way.

It draws you in and you find yourself transported to battlefields and war rooms of the past. I’ve always taken cryptography for granted - I type https into my browser and navigate to a site and all’s well. I know things are reasonably secure - but why?

It turns out that RSA, the algorithm that underpins things like SSL and SSH, is a landmark of human achievement and did something that millennia of mathematicians and scientists could not: provide secure, end-to-end encryption. A wonderful story.

Good intelligence is the key to winning any war.

The work of Bletchley Park in the Second World War is well known. The equally important role that the enigmatically named Room 40 played in the First World War is less well known.

This book unravels the story of this formidable naval code breaking and intelligence unit. It was made up of men from all walks of life, under the leadership of the maverick genius and spymaster, Rear-Admiral ‘Blinker’ Hall.

Without the work of Room 40 there would have been no naval battles at Dogger Bank and Jutland. The U-Boat campaign against commerce would have been much harder to overcome. Most importantly, read how their work on the infamous Zimmermann Telegram led directly to the American declaration of war.

An amazing storyteller and unrivalled expert on World War II, Sir Max is best in class when it comes to combining the big and little pictures. He renders pithy judgments on thorny subjects. This may be the best overview of intelligence from east to west, north to south in World War II. Again like David Kahn and Christopher Andrew, Sir Max is generous to fellow writers and gracious to readers. I remember a talk at a Washington, DC bookstore to which a reader brought a stack of Hastings books—perhaps 10 or so—for his autograph. Sir Max did not hesitate, cheerfully reaching for his pen.

The Book of Satoshi by Phil Champagne offers an unbiased, first-hand view of Satoshi Nakamoto, the anonymous architect behind the world's largest peer-to-peer system. As a former distributed systems researcher, I was fascinated by Satoshi's technical proficiency and cryptographic genius.

Champagne meticulously curated all of Nakamoto's publicly available writings, from emails to forum posts, presented in chronological order, providing an unparalleled window into the mind of a polymath in computer science, systems theory, cryptography, and even economics theory and community management.

A warning: the book is very technical at times, and some parts will get boring for a non-technical reader not interested in distributed systems.

A simple (not perfect) test of whether you’re going to love this book: Just check out the author’s blog, called “shtetl-optimized”. The style is similar: sharp, funny, mixing professional theoretical Computer Science with broader takes.

I am still in the middle of the book, and nevertheless, I’m happy to recommend it. As an amateur with superficial CS knowledge, I am enjoying this introduction to classical complexity theory and the basic theory of quantum computation.

Aaronson’s distinctive style makes the ride all the more enjoyable. It’s neither a “real” textbook nor a pop-science book. It’s in a weird space somewhere in between, and I love it!

A thrilling personal account by the brilliant cryptographer, Leo Marks, who was only 22 when employed by the SOE. It was Marks who gave the special codes to famous SOE agents like Violette Szabo, Noor Inayat Khan, and Nancy Wake before they left for the field. An insight into how the code war between Germany and England played out, often with disastrous consequences.

About WWII codebreaking, the reason this makes my ‘Best 5’ is that, besides being constantly inventive and informative, it’s also very funny. (I’m that shallow.)

There are similarities, I think, with Catch 22, in the plot’s intelligence, absurdity, and dreamlike turns.

I think Stephenson’s character Bobbie Shaftoe, a soldier who carries out counterintelligence deceptions, is hilarious. Also, Stephenson’s use of real historical characters–he presents believable portraits of Alan Turing, Douglas MacArthur, Karl Dönitz, and Hermann Göring, with a walk-on appearance by Albert  Einstein–gave me license to do so in my own fiction.

I can never understand why so many critics and readers are snooty about Dan Brown. For me, he does what every good storyteller should do: takes you on a page-turning journey. And his style is both readable and erudite, whatever the snobs might say.

Although this could technically be described as a crime thriller, it remains perhaps Brown’s best action-adventure so far, and regardless of whether Tom Hanks is your idea of Professor Robert Langdon or not, the thrills just keep on coming as you follow breathlessly through the streets and landmarks of Paris, London and beyond. Stylish and swaggering.
