This book was written in 1999, so the information is a little dated. There is no mention of AES, lattices, or elliptic curves, but the information the book does cover is substantial. The author describes the cryptanalytic process for each cipher discussed in detail, even going pretty deep into quantum cryptography, for which he explain's Heisenberg's uncertainty principle, superposition, and photon spins.

There is a full section on linguistics and the deciphering of hieroglyphics and Linear B, as well as overviews of the lives of dozens of cryptographers and cryptanalysts like Alan Turing, Martin Hellman, and Whitfield Diffie. ( )

Humpty Dumpty: "The Code Book - The Science of Secrecy from Ancient Egypt to Quantum Cryptography" by Simon Singh

“[ ] One-way functions are sometimes called Humpty Dumpty functions. Modular arithmetic, sometimes called clock arithmetic in schools, is an area of mathematics that is rich in one-way functions. In modular arithmetic, mathematicians consider a finite group of numbers arranged in a loop [ ].”

The two greatest hazards of the internet are pornography and security. I have no idea how this is so, or how these myths have become so dominant in our collective consciousness. In fact is that quality pornography is available from the bookshops (so I’ve been told…), and the internet is fundamentally more secure than the world it’s replacing. There’s only one catch: one should not be stupid!

Many Internet services are in it just for the money, i.e., they sell data they collect about us customers and users. This applies both to information I post intentionally and also to the hidden parts of my information footprint. Even paid apps and services often collect data about me; it’s not a question of paying more money; even if you pay more there’s no guarantee that service in question isn’t also profiting indirectly by selling my data. Most of the time what happens is even worse: the data is sold to other 3rd-party services that aggregate data from many primary sources, making it even more valuable. My information may be innocuous or just annoying, for example, which online ads I usually see, but in the worst-case scenario, digital information can be used against me. Data from cell phones, email accounts, computer hard drives, and other sources can be used by others (sigh). The history of Cryptography has always been a struggle between the code makers, and the code breakers, with sometimes one and sometimes the other having the ascendancy. In today’s society, I think the code breakers are getting the upper hand…

This book was a well written and comprehensive review of the history of codes. Those with a bent for maths will definitely enjoy it, but even those who would rather avoid anything to do with numbers would enjoy the stories behind the discoveries. I never knew why prime numbers were so important until now. A great read. ( )

One of the most intriguing and interesting books I've read in a very long time. This was actually a required textbooks for a friend's college course, and I borrowed it after he was done with the class. I literally read it in five days. Me, having studied linguistics, absolutely loved everything this had to offer. From the story of Mary Queen of Scots to cracking the German Enigma cipher to encryption in the digital age, there was simply so much to learn that I couldn't put it down.

This book was written in 1999, back when the digital age was picking up enormous speed. I can only imagine what changes in codes and encryption have happened since then, and hope that Singh would come out with an updated version of this book sometime in the future.

Must read for puzzle and language and math lovers. ( )

I remember being very much at awe, reading about Fermat's Last Theorem (same author), but this book really didn't tell me anything new, except for some historical gossip on important figures in the history of cryptography. Probably, having a degree in mathematics and computer science doesn't help in appreciating this book... :-) ( )

The urge to discover secrets is deeply ingrained in human nature; even the least curious mind is roused by the promise of sharing knowledge withheld from others. Some are fortunate enough to find a job which consists in the solution of mysteries, but most of us are driven to sublimate this urge by the solving of artificial puzzles devised for our entertainment. Detective stories or crossword puzzles cater for the majority; the solution of secret codes may be the pursuit of a few.

Amazon.com Amazon.com Review (ISBN 0385495323, Paperback)

People love secrets. Ever since the first word was written, humans have sent coded messages to each other. In The Code Book, Simon Singh, author of the bestselling Fermat's Enigma, offers a peek into the world of cryptography and codes, from ancient texts through computer encryption. Singh's compelling history is woven through with stories of how codes and ciphers have played a vital role in warfare, politics, and royal intrigue. The major theme of The Code Book is what Singh calls "the ongoing evolutionary battle between codemakers and codebreakers," never more clear than in the chapters devoted to World War II. Cryptography came of age during that conflict, as secret communications became critical to both sides' success.

Confronted with the prospect of defeat, the Allied cryptanalysts had worked night and day to penetrate German ciphers. It would appear that fear was the main driving force, and that adversity is one of the foundations of successful codebreaking.

In the information age, the fear that drives cryptographic improvements is both capitalistic and libertarian--corporations need encryption to ensure that their secrets don't fall into the hands of competitors and regulators, and ordinary people need encryption to keep their everyday communications private in a free society. Similarly, the battles for greater decryption power come from said competitors and governments wary of insurrection.

The Code Book is an excellent primer for those wishing to understand how the human need for privacy has manifested itself through cryptography. Singh's accessible style and clear explanations of complex algorithms cut through the arcane mathematical details without oversimplifying. --Therese Littleton

"In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. "Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is"--Publisher's description.… (more)
