Codes have decided the fates of empires, countries, and monarchies throughout recorded history. Mary, Queen of Scots was put to death by her cousin, Queen Elizabeth, for the high crime of treason after spymaster Sir Francis Walsingham cracked the secret code she used to communicate with her conspirators. And thus the course of British history was altered by a few sheets of cryptic prose. This is just one link in humankind's evolutionary chain of secret communication, and just one of the fascinating incidents recounted in The Code Book, written by bestselling author Simon Singh.
Combining a superb storyteller's sense of drama and a scientist's appreciation for technical perfection, Singh traces the evolution of secret writing from ancient Greek military espionage to the frontiers of computer science. The result is an epic tale of human ingenuity, with examples that range from the poignant to the peculiar to the world-historical.
There is the case of the Beale ciphers, which involves Wild West escapades, a cowboy who amassed a vast fortune, a buried treasure worth $20 million, and a mysterious set of encrypted papers describing its whereabouts--papers that have baffled generations of cryptanalysts and captivated hundreds of treasure hunters.
A speedier end to a bloody war was the only reward that could be promised to the Allied code breakers of World Wars I and II, whose selfless contributions altered the course of history; but few of them lived to receive any credit for their top-secret accomplishments. Among the most moving of these stories is that of the World War II British code breaker Alan Turing, who gave up a brilliant career in mathematics to devote himself to the Allied cause, only to end his years punished by the state for his homosexuality, while his heroism was ignored. No less heroic were the Navajo code talkers, who volunteered without hesitation to risk their lives for the Allied forces in the Japanese theater, where they were routinely mistaken for the enemy.
Interspersed with these gripping stories are clear mathematical, linguistic, and technological demonstrations of codes, as well as illustrations of the remarkable personalities--many courageous, some villainous, and all obsessive--who wrote and broke them.
All roads lead to the present day, in which the possibility of a truly unbreakable code looms large. Singh explores this possibility, and the ramifications of our increasing need for privacy, even as it begins to chafe against the stated mission of the powerful and deeply secretive National Security Agency. Entertaining, compelling, and remarkably far-reaching, this is a book that will forever alter your view of history, what drives it, and how private that e-mail you just sent really is.
Included in the book is a worldwide Cipher Challenge--a $15,000 award will be given by the author to the first reader who cracks the code successfully. Progress toward the solution will be tracked on The Code Book website.

前面的若干章都是老生常谈包括enigma什么的也都是文献综述,最后一章的alice-bob密钥交换实验是全书精华,轻松理解量子密钥。不过量子计算机还是很遥远的。

评分Superb
评分结合历史发展介绍密码和解密学的发展,很浅显的书。前面写得比较精彩,RSA加密算法部分数学的原理没有讲透彻,看得不够爽。不知道作者是不是有意为之。作者对目前发展出来的加密算法也太有信心了吧?我个人是相信加密算法一定有被破解的一天的。
揭开秘密的冲动是人类根深蒂固的天性。就是最不好奇的心,也会为即将得知他人的秘密而悸动。有些幸运的人能以解谜为业,我们大部分的人却得靠解开那些供消遣之用的矫造谜语来满足这种欲望。对一般人而言,侦探故事或纵横字谜便已足够,极少数人则是以破解玄秘的符号为志业。 约...
评分几个世纪以来,密码的故事总能让人神魂颠倒,它总是与阴谋诡计、探寻宝藏、遗嘱确立、特务间谍这些传奇故事息息相关。编码和解码就如同盾与矛,这一防一攻构成了密码学这门技术科学。3000年来,在这场攻防拉锯战中,语言学、数学、通信学、物理学、计算机学等各类学科纷纷投入...
评分曾经翻过这本书,把密码学的原理从古代讲到当代,故事非常精彩,读者看起来也不会觉得累。估计新书很难买到了,因为去年曾经需要买几本新书送人,结果北京的书店和经销商处都没有。只好联系出版社,但也只剩下五本书了。为了不耽误送人的时间,等不及汇款去再邮寄过来,只好托...
评分1586年10月15日星期三早上,苏格兰玛丽女王受到叛逆罪的庭审。主要证据是截获的玛丽与安东尼·贝平顿的来往信件。它们经过一番伪装,表面看上去很普通,实际上包含了一起阴谋——针对伊丽莎白女王的刺杀计划。英国情报部门成功破译密码,遏制了一起尚未成型的凶案,最终把玛丽...
评分牛牛是某大学计算机系的大二学生,小伙儿颜值很高,而且也潮,一点儿也没有技术宅男的气质。性格也很顺和,平时不管讨论什么,或者开他开涮开黑开玩笑,他都总是笑眯眯的。我有次很好奇的问他: 你是不是从不生气啊? 他顿时一脸的苦相: 谁说的,每次放假回家回到家里那些亲戚...
