图书描述

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.

很生动 又不失准确

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。

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...

这本书就是沿着密码发展的历史线条一路讲下来,其中密码作为vital part影响的事件和迷思也有所记录和发展。 譬如queen marry,带铜面具的人还有二战中密码扮演的重要角色。 相比编密码的人,作者对破译密码的人着墨更多,有些人真的是有猎犬般的敏锐嗅觉,当然还有坚韧的耐力和...

异常精彩的一本书,介绍了两千多年来编码与解码的战争。 编码与解码双方费尽心机、各施奇技,编码者一次次建立起坚不可摧的铜墙铁壁,而解码者一次次孕育出厚积薄发的摧枯拉。历史在曲折中前进,密码在挫折中完善,如今的编码者倚靠RSA取得了这场竞争的优势地位。使用目前的方...
