过去五年间，美国陆海军与英国政府公开了上百万页有关二战破译密码的新档案。如今，Battle of Wits 呈现了这些档案所揭示的战争史。从 battle of Midway 到1945年1月破译最后一个德国密码，这是一部令人惊叹的战争史诗，生动展现了这场战争不仅靠硬实力取胜，更靠识破敌方意图而赢下。Stephen Budiansky 这部引人入胜的史作所揭露的内幕包括：英国如何试图操控美国密码破译人员，以及垄断德国 Enigma code

布迪安斯基笔头很好：他写的关于二战恩尼格玛（Enigma）密码破译的《智力交锋》（Battle of Wits）很值得一读，尽管大部分内容是把其他二手资料重新炒了冷饭。我大概会去找这本哥德尔传记翻翻看，不过从精神疾病切入的角度听起来挺……
Budiansky is a good writer: his "Battle of Wits" about WW2 Enigma cryptanalysis is worth reading, even though it is mostly rehashed from other sources. I'll probably try to check out this Gödel biography, though the mental illness angle sounds pretty…
任何人如果想了解更多二战密码战历史，把目光投向图灵之外的其他人物（当时的阵容庞大而且形形色色），都应该读读《智力交锋》（http://www.amazon.com/dp/0743217349），这位历史学家是在1996年NSA大批档案解密后写下它的。波兰密码破译人员的经历甚至更加硬核，你在书中会读到……
Anyone who wants more of a history of WW2 crypto that extends the cast of characters beyond Turing (and the cast was significant and varied) should read "Battle of Wits" (http://www.amazon.com/dp/0743217349) the historian who wrote it wrote it after a large NSA declassification in 1996. What's even more extreme about the Polish codebreakers, a story you would read in…
另一个因素（根据布迪安斯基那本精彩的《智力交锋》所述）是德国人过度自信，坚信恩尼格玛坚不可摧。事实证明，他们以为破译恩尼格玛所需的超强算力绝不可能实现，这种自信是大错特错的。
Another factor (according to the excellent Battle of Wits by Budiansky) was that the Germans were overconfident that Enigma was unbreakable. Turned out their confidence in the hard computation that would need to be done to decode Enigma was wrong.
要回答这个问题得写整整一本书！你可以参考的一本书是斯蒂芬·布迪安斯基写的《智力交锋》，自由出版社（The Free Press）2000年出版，ISBN: 0-684-85932-7。布莱切利园从不是靠某一次突破就搞定的。Bombe解密机（后来造了好多台）发挥了很大作用……
To answer that would take an entire book! One book you might try is "Battle of Wits" by Stephen Budiansky, published in 2000 by The Free Press. ISBN: 0-684-85932-7 There was never a single break through at Bletchley. The Bombe machines (there were eventually many of them) were useful,…
给对此感兴趣的朋友们 ——《智力交锋》是一本关于二战密码分析的极好读物。
For anyone interested in this stuff - “Battle of Wits” is a great book about cryptanalysis in WW2.
我这周在读斯蒂芬·布迪安斯基写的《智力交锋：二战密码破译全史》。美国情报界一直以来都有个传统，就是直接去找通信源头，从公共……获取原始数据。
So this week I've been reading Battle of Wits: The Complete Story of Codebreaking in World War II by Stephen Budiansky. The US intelligence community has a long history of going right to the communication source and obtaining raw data from public…
