  Bruce应该是当代最出名的密码学家了，这本书毫无疑问是当代最杰出的密码学教材

  讲述很形象，应该是这门科学本身太生涩了吧，反正我知道拿到这本书的人没有一个读完它

  自动执行协议（self-enforcing protocol）是协议中最好的。协议本身就保证了公平性，不需要仲裁者来完成协议，也不需要裁决者来解决争端。协议的构成本身使得不可能发生争端。如果协议中的一方试图欺骗，其他各方马上就能发觉并且停止执行协议。无论欺骗方想通过欺骗来得到什么，他都不能如愿以偿。每个协议最好都是自动执行协议。不幸的是，对于所有情形，都没有一个自动执行协议。

  Factoring large numbers is hard. Unfortunately for algorithm designers, it is getting easier. Even worse, it is getting easier faster than mathematicians expected. In 1976 Richard Guy wrote: “I shall be surprised if anyone regularly factors numbers of size 10^80 without special form during the present century”. In 1977 Ron Rivest said that factoring a 125-digit number would take 40 quadrillion years. In 1994 a 129-digit number was factored. If there is any lesson in all this, it is that making predictions is foolish.

  There are many cryptographic algorithms. These are three of the most common:- DES (Data Encryption Standard) is the most popular computer encryption algorithm. DES is a U.S. and international standard. It is a symmetric algorithm; the same key is used for encryption and decryption.- RSA (named for its creators - Rivest, Shamir, and Adleman) is the most popular public-key algorithm. It can be used for both encryption and digital signatures.- DSA (Digital Signature Algorithm, used as part of the Digital Signature Standard) is another public-key algorithm. It cannot be used for encryption, but only for digital signatures.
