为什么值得读
- 聚焦二战实战中密码与纸笔加密的实际难题
- 揭示战时英国间谍活动的疏漏与内情
- 详述电报员个人发报风格如何用于谍战伪装
Special Operations Executive (SOE) 作为二战期间渗入帝国统治下欧洲各地的英国特别行动执行处，在战争初期和中期一直面临着在法国某些地区悬而未决的难题。他们培训新特工，将其空投至法国境内，记录下他们与当地特工的接头……随后他们便杳无音信，推测已被捕或牺牲。有两件事必须尽快解决：第一，必须建立一个全新的网络，以免新特工受到已被发现的旧网络牵连；第二，必须采用一种密码生成机制，使前线特工无法获悉其他……

……信息，现在选择太多了，但我最喜欢的有两本（一本经典，一本较新）[4] 戴维·卡恩的《破译者》（The Codebreakers），https://en.wikipedia.org/wiki/The_Codebreakers [5] 里奥·马克斯的《丝与氰化物：一个密码制造者的故事 1941-1945》（Between Silk and Cyanide: a Codemaker's Story 1941-1945，这本书讲的与其说是密码学，不如说是二战期间密文和密码系统的实际应用问题）。* 托马斯·杰斐逊轮盘密码或巴泽里圆柱密码（Bazeries Cylinder）……
…information, there are so many to choose from now but two of my favorites (one old and one more recent) [4] David Kahn, The Code Breakers, https://en.wikipedia.org/wiki/The_Codebreakers [5] Leo Marks, Between Silk and Cyanide: a Codemaker's Story 1941-1945 (this is less about cryptography and more about the practical problems of secret code and ciphers during WWII). * The Thomas Jefferson wheel cipher or Bazeries Cylinder…
……它与另一种密码是同构的，除了一些让它变得更简单的修改之外完全一样。他们可能已经证明了瞎搞 joker 牌根本没用，但我不太确定。里奥·马克斯写的《丝与氰化物：一个密码制造者的战争 1941-1945》（Between Silk and Cyanide: A Codemaker's War, 1941-1945）深入探讨了战时纸笔加密系统的实际问题。英国人带着 Playfair 进入了二战，而这不过是个稀烂的置换……
…that it's isomorphic to a cypher which is the same except for some modifications which make it simpler. They may have proved that the fooling around with the jokers doesn't help, but I'm not sure. "Between Silk and Cyanide: A Codemaker's War, 1941-1945", by Leo Marks, goes into the practical problems of paper and pencil encryption systems in wartime. The British went into WWII using Playfair, which is a crappy transposition…
……通信。他们还破译了1941年12月7日之前及之后日本的所有通讯。值得注意的是，FBI 从来没有任何密码分析能力。他们得到的情报全是从弗里德曼夫妇（the Friedmans）那里来的。里奥·马克斯写的《丝与氰化物》（Between Silk and Cyanide）极具启发性，尤其是关于当时的谍报技术及其在英国的失误。
…traffic. They also decrypted all Japanese communications leading up to Dec 7, 1941, and after. Notably, the FBI never had any capacity for cryptanalysis. What they got, they got from the Friedmans. "Between Silk and Cyanide", by Leo Marks, is deeply enlightening, in particular about spycraft and its failings in Britain at the time.
……你拿业余无线电操作员的发报手法风格来举例，挺有意思的。在二战中，这被称为操作员的“fist”（手法特征）。推荐你看看里奥·马克斯的杰作《丝与氰化物》（Between Silk and Cyanide）的附录一，里面就记录了一则敌对双方如何研究并伪造彼此手法来进行欺骗的案例。（以后你发现这书有多棒时再来谢我吧。）可能没有……
…amusing that you would cite the example of the style of code keying of amateur radio operators. In WWII this was know as the "fist" of the operator. I refer you to appendix one of Leo Marks' excellent book "Between Silk and Cyanide" for just one account of how the opposing sides were able to study and fake each others' styles to create subterfuge. (You can thank me later for turning you on to a fantastic read.) There may not be…
……匹配得那么好。这本书极好地描述了二战中特工和前线部队对 crypto 的实际应用：http://www.amazon.com/Between-Silk-Cyanide-Codemakers-1941-1... 里奥·马克斯 - 《丝与氰化物：一个密码制造者的战争 1941-1945》（Between Silk and Cyanide: A Codemaker's War, 1941-1945）
…fit nearly so well. This is a great book to describe the practical use of crypto by agents and troops in the field in WWII: http://www.amazon.com/Between-Silk-Cyanide-Codemakers-1941-1... Leo Marks - Between Silk and Cyanide: A Codemaker's War, 1941-1945
我推荐里奥·马克斯的《丝与氰化物》（Between Silk and Cyanide）。
I recommend "Between Silk and Cyanide" by Leo Marks.
