……我说的是，如果你哪天发现自己急需一本优秀的密码学参考书，那这本书绝对物超所值。其他不错的参考书还有 Katz 和 Lindell 写的《Introduction to Modern Cryptography》、Goldreich 写的《Foundations of Cryptography》（上下两卷），以及 Kahn 写的《The Codebreakers》（偏密码学历史）。当然还有别的优秀参考书，不过我发现自己查得最多的还是上面这几本。然而，我……
…when I say that the text is well worth the price if you ever find yourself needing a good cryptography reference. Some other good references are Introduction to Modern Cryptography by Katz and Lindell, Foundations of Cryptography by Goldreich (both volumes), and The Codebreakers by Kahn (for history of cryptography). There are other good references, of course, but I find myself referring to the ones above the most. However, I…
如果你想从更“偏理论”的角度来审视这套理论，Jon Katz 和 Yehuda Lindell 合著的《Introduction to Modern Cryptography》是一本神书。另外 Oded Goldreich 的《Foundations of Cryptography》也很棒（不过我买的那本有不少印刷错误）。
If you want a more "theoretical" look at the theory, Introduction to Modern Cryptography by Jon Katz and Yehuda Lindell is a great book. Also good (but my copy had many printing errors) is Foundations of Cryptography by Oded Goldreich.
……——对此我想说，我认识该领域的科研人员，哪怕只是简单算一下 run rate 也表明这很快就会变得可行……我好奇的是，如果你读了 Oded Goldreich 的《Foundations of Cryptography》，你的看法会不会有所转变？
…— to which I can say that I know researchers in the space and even a simple run rate calculations indicates this will be feasible soon... I wonder whether your stance would update if you were to read Foundations of Cryptography by Oded Goldreich?
……补充：去刷 Jonathan Katz 和 Dan Boneh 的 MOOC（链接在帖子里）。想达到能够“设计/分析加密协议”（并且大概清楚自己在干嘛）的水平：* 读 Oded Goldreich 的《Foundations of Cryptography》（第 1、2 卷）* 尝试跟真正的密码学学者进行一些看起来不太小白的交流（博文里有相关建议）* 去一所密码学实力雄厚的高校读个 PhD。编辑：调整了格式
…Supplement: Take Jonathan Katz' and Dan Boneh's MOOCS (links in post) To get to the point where you can "design/analyze crypto protocols" (and maybe know what you're doing): * Read Oded Goldreich's Foundations of Cryptography (Volumes 1&2) * Try to have quasi-intelligent conversations with real cryptographers (advice for this in blog post) * Get a PhD somewhere with a good crypto program edit: formatting
……挺好的。经典的“应用”类著作是 Schneier 的《Applied Cryptography》，但注意那本书有不少问题。据说他后来的新书《Cryptography Engineering》要好得多。Goldreich 的《Foundations of Cryptography》非常扎实，但需要相当多的先验知识，而且理论性极强。
…good. The classical "applied" work is Schneier's Applied Cryptography", but note there are a lot of issues with that work. His newer book, "Cryptography Engineering", is supposedly better. Goldreich's Foundations of Cryptography is quite solid, but requires quite a bit of background and is very theoretical.
……对于那些想认真钻研密码学但接触并不深的人来说，这本书是个很棒的推荐。而且它不预设读者精通计算机科学的方方面面，这一点很赞。Goldreich 的《Foundations of Cryptography》则更像是一本关于理论密码学的专题论著……它探讨得要深得多，而且一上来就默认读者对理论计算机科学和概率论的相关概念已经非常熟悉。其……

It also doesn't assume the reader is an expert in all things computer science, which is nice. Goldreich's Foundations of Cryptography is more of a treatise on theoretical cryptography... it goes much deeper and starts out assuming the reader is pretty familiar with concepts from theoretical computer science and probability theory.
