Good enough, but suffers from the typical problems of pop-science-history stuff: obsession with a limited number of personalities, repetition of accepted truths about history, nationalism, focus on "stories", dilution of information about the process of cryptography etc. Still interesting ( ) On the surface of it, The Code Book is a very unglamorous book - a somewhat analytical book filled with technical jargon on the history of cryptography, starting from its first mentions in written record to the somewhat confusing introduction to quantum computing and quantum cryptography. But on a deeper glance, Simon Singh reveals himself as a passionate and intense geek who wants to explain how our communication is encrypted and decrypted to laypeople, who might not know what algorithms and modulus functions are but who deserve to know what cryptography is. It is telling that most of the concepts he teaches are through stories - why a particular cypher was invented and how history could have been much different if a few specific messages were still secure. It was heartening to note that even knowing all the basics - there was a lot of stuff to absorb - including the inner workings of Enigma used in WW2, the decryption of Linear B, an extinct Mediterranean language. The Code Book's ending chapters have dated horribly, though. Simon envisioned a future where the public would need cryptography because they would be emailing forms containing their credit card information to retailers for e-commerce. Amazon took this concept to a hitherto unforeseen level. Moore's Law has stagnated, the debate on cryptography has changed immensely, for better or worse - and quantum computing remains as nascent as ever. Still, the basics of cryptography have remained the same - for that alone; this is a fine read. Simon Singh ofrece la primera historia arrolladora del cifrado, trazando su evolución y revelando los efectos dramáticos que los códigos han tenido en las guerras, las naciones y las vidas individuales. Desde María, reina de Escocia, atrapada por su propio código, hasta los codificadores navajos que ayudaron a los aliados a ganar la Segunda Guerra Mundial, hasta el increíble (e increíblemente simple) avance logístico que hizo seguro el comercio por Internet, The Code Book cuenta la historia de el arma intelectual más poderosa jamás conocida: el secreto. nessuna recensione | aggiungi una recensione
