Amazon Summary
The magnificent, unrivaled history of codes and ciphers—how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage—updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

Code by Petzold (https://www.amazon.com/Code-Language-Computer-Hardware-Softw...) - non-technical (in the sense it isn't something to "work through"), covers a lot of interesting topics. Especially approachable for that age.

Elements of Computing Systems by Nisan & Schoken (https://www.amazon.com/Elements-Computing-Systems-second-Pri...) - more technical (has content to work through). I've read the first edition, not the second. Has a companion site: https://www.nand2tetris.org. It's well-written, and a motivated high schooler could work through it.

The Code Book by Singh (https://www.amazon.com/Code-Book-Science-Secrecy-Cryptograph...)

The Codebreakers by Kahn (https://www.amazon.com/Codebreakers-Comprehensive-History-Co...)

I was always interested in ciphers and such as a kid so those two books got my attention when I found them in high school/college. I'm a bit fuzzy, now, about which one I was more interested in but both were good books. (I still have them, may give them a re-read next month.)

There are a few others I have in mind, but just can't recall the titles at the moment.

A good read about the crypto behind the Enigmia and other encryption approaches. A fun read.

"The Codebreakers" cited above, is a massive history of cryptography. The same author, David Kahn, has written a book focusing on the Enigma called "Seizing the Enigma".

Thanks, I'll have to read that one.

The Codebreakers: The Comprehensive History of Secret Communication[0] by David Kahn is probably the best book in this area. Be warned it sits on many bookshelves but due to its length few are the number that have finished it, none the less it is an extremely rewarding read. It has oddles and oddles of stories about cryptographers you have never heard of doing awesome things, including the history and personalities behind many of the Black Chambers of Europe.

It puts the Code Book to shame.

$55 - Kindle price? $20 more than the paper version? Nice try, amazon!

Really a better list is by tom his own self: http://www.amazon.com/lm/R2EN4JTQOCHNBA/ref=cm_lm_pthnk_view...

My recommendations would add:

http://www.amazon.com/The-Codebreakers-Comprehensive-Communi... by David Kahn. Many stories of the whole history of secret communications, with lessons in op-sec, not changing the codes frequently enough, they can't possibly break this.

The John LaCarre http://en.wikipedia.org/wiki/John_le_Carr%C3%A9 books. Do you remember the point where someone says to Smiley "There is no reason to think that they tapped the phone" to which Smiley replies "There is Every reason".

A must read, I tell my students in my Security Awareness training classes is The Cuckoo's Egg http://www.amazon.com/The-Cuckoos-Egg-Tracking-Espionage/dp/.... Examples like default service accounts on Dec Vax with username Field and password Service. Note when this is written and are our habits really any better with junk hung on the internet? Concepts pioneered in his book, as effective as they are, are not practiced. Note the alarms going off, ignored, at a large retailer last thanksgiving. Or another retailer recently, "Wait, what, we are being attacked? I didn't feel anything".

Most vulnerable is the thinking "Well, they can't get our X because <thing we did>". I have a matrix of attacker motives and what they are after. There motives and targetsyou haven't thought of.

The first book on that list "Grey Hat Python" isn't very good. It contains some good parts but it skips things like Scapy which a consider a superb tool if you are in the pentesting business. I recommend reading "Violent Python" instead. It's everything that Grey Hat should have been...

I got Codebreakers over 15 years ago, and I still haven't finished it. That thing is incredibly dense.

I don't know if this is a recommendation, an anti-recommendation, or an excuse.

TerryL22
I totally agree with you, this actually has happened to me, not once, but twice. It took me 7 years to get it off! I think there are a few recommendations for it.

At the very least, it's a challenge to all the habitual readers on HN.

I can second the recommendation for The Cuckoo's Egg. I picked it up somehow in 1994 or so and was immediately impressed.

I hear there's an alternate title it's being published under now though, so look for the author, Cliff Stoll.
