Code Breaking: A History and Exploration Reviews
I loved this book. Mr. Kippenhahn's use of historical antecdotes and relating each technique to its predecessors allows anyone -- technically minded or not -- to be drawn into his unfolding story. The fact that he presents the mathematics in an easy to understand yet thorough manner makes it especially enjoyable for readers who want to understand each principle. Having read it from cover to cover, I intend to read it again, and spend more time on a few techniques that I brushed over on the first read.If you enjoy puzzles, or technology in general, or wish to understand the techniques that are making electronic banking a reality, read this book.
Bought this book Thursday 23 Sept in Baton Rouge, Lousiana, and throroughly enjoyed reading it from start to end within the next 36 hours on the long way home to Sweden. Recommended for eveybody who wants a "flying start" into the cryptologi subject. My next action is to download PGP!
I wanted to understand cryptology, with enough math behind various techniques and yet I don't want to be bored with the details. This book delivers.The entertaining historical stories are icing on the cake and make it hard to put down.
Rudolf Kippenhahn wrote this in German, it was translated into English by Ewald Osers. Mathematician Kippenhahn wrote this very readable book because of his interest in cryptology. It covers a very technical subject and makes it easy to understand for the average reader. The German authorship gives it a viewpoint that differs from the American or English books on this subject. Most of the chapters run about 20 pages. Only a few books are listed for further reading.The short chapters and the well-written text makes it a quick-paced read. Chapter 8 describes "Shuffled Texts" and their historic use by scientists. Chapter 9 tells of rotors and their use in enciphering. It tells of the secret of the Enigma and its hidden flaw. `Ultra' helped to win the Battle of Britain and was crucial to the Battle of the Atlantic (Chapter 10). The author does not mention Vernam's invention was used in 1917; its no secret (p.201). The decipherment of teletype messages led to the development of electronic computers. [The cover name for this was "weather research".] Governments intercept and decipher messages from other governments, and people (Chapter 11). Kippenhahn discusses the encryption of messages using public and private keys (Chapter 12). Is PGP safe from any government (p.232)? Chapter 13 tells about banking with Smart Cards. These are used in Europe and store more information than on a magnetic strip (pp.245-246). A charged money card is possible for electronic money (p.249). This does not protect anonymity. There are other problems (p.254). A signature on a fax can be copied to another fax (p.255). A separate message is needed to authenticate it (p.256). RSA encryption can't be cracked by a lone hacker, only by a large scale effort (p.261). Your government is using your tax money for this.
Code Breaking is a riveting read, replete with historical references ranging from Thomas Jefferson's wheel to the German Enigma. Caesar. Galileo. Edgar Allen Poe. Sherlock Holmes's . Mary Queen of Scots. Vigenere tableau.If you are delving into cryptology, add this book to your library... it is well written and organized. Rudolf Kippenhahn's passion for the subject is infectious.My only question for the author is: Why haven't you cracked Kryptos?(the still unsolved puzzle in front of the CIA headquarters created by Sculptor Jim Sanborn in 1990). There is still a fourth section at the bottom of Kryptos consisting of 97 or 98 characters which remains uncracked. Anyone else game?
I'm not sure why a previous review written by me on this book showed only one star, but that is an error. This is a 4-star book. Here is my previous review:Mr. Kippenham has written a thoroughly enjoyable book! I've read a great many books on Cryptology, and while his book won't make you an expert, it gives descriptions and explanations superior to many other "beginner texts". In fact, the explanation of the mathematics involved in RSA encryption is the most lucid and easy to understand that I have yet read. Much of the book is a rehash of some other good crypto books like "Decrypted Secrets" and Beutelspacher's "Cryptology", but at least Kippenham puts it all together in an easy to understand style. For a more comprehensive history while still an enjoyable read, try Simon Singh's "The Code Book", the book that started me on my expensive journey of "collecting" crypto books, and if you're still interested, David Kahn's "The Codebreakers" is the holy grail of Crypto history, but a bit more dry. BEWARE. . .you may get hooked like me! Then the American Cryptogram's Classic Crypto Book Service or Aegean Park Press (both of whom specialize in Crypto books) will be "collecting" some of your money!
It is very difficult to find a book on the subject of Cryptology which does not go into great detail about the math, forgoing the necessary context to understanding. I have read many book on the subject and wish I had read this one first, if not early on.Kippenhahn has accomplished that which others haven't. Providing the historical context based upon a particular crypto advancement. Instead of the entire history of the subject, he provides sections of chapters which focus on some aspect of the history, not for history sake, but to have the reader understand a particular advancement or application of cryptology.By understanding, I'm talking about providing a lot of visual material. Monalphabetic maps, key tables, turning grilles, Vigenere tables, and others. All of these are very clearly displayed and understandable by any student or adult. He also provides simple "schematics" for cipher machines (switches and lights), which again give you the context to then understand (conceptually) what is behind Enigma machines and the like.He introduces symmetric and asymmetric systems, such as DES and RSA respectively. First conceptually, then with a bit more detail behind it. His discussion on RSA includes an appendix which explains the math to mere mortals. Actual example keys are derived using two examples. If you're interested in why the math "works" you'll need to refer to another source. This shows the process for creating N, E, and D, the keys which support an RSA keyset.An introduction to the application of some of the techniques in the book include some theoretical banking examples, and smart cards.In summary, unless you already have an advanced understanding of the subject matter and math, I strongly encourage you to obtain and enjoy this quite readable 260 page book. You'll finish it fairly quickly and have enough of an understanding of the field to delve deeper if you wish - but won't have to.
