代写代考计算机密码学Cryptography exam作业

1.课本概述

Cryptography Theory And Practice

这门课确实是令人抓狂，就连博士也会恐惧密码学，

七年之后，博士毕业时，或许你的这种感觉还会存在（好像什么也没学会）

学习内容和个人能力的要求来说，密码学偏基础学科，对于数学逻辑的要求比其他学科要强一些，另外密码学和IT结合紧密，所以学密码的同时还需要对于IT信息技术有一定的了解。如果要深入，必然是需要读研和读博的，如果不读研不读博，其实到时候就业的面也比较广，密码和许多行业比如金融、政务、能源、交通等行业都有比较紧密的结合。

由于属于朝阳产业，而后在这个行业内发展会比较平稳，少有机会会像互联网行业一夜暴富，但是也不会像互联网行业那样一夜裁员的事情发生。

The development and deployment of a cryptosystem must address the issue of security. Traditionally, the threat that cryptography addressed was that of an eavesdropping adversary who might intercept the ciphertext and attempt to decrypt it. If the adversary happens to possess the key, then there is nothing that can be done. Thus the main security consideration involves an adversary who does not possess the key, who is still trying to decrypt the ciphertext. The techniques used by the adversary to attempt to “break” the cryptosystem are termed cryptanalysis.
The most obvious type of cryptanalysis is to try to guess the key. An attack wherein the adversary tries to decrypt the ciphertext with every possible key in turn is termed an exhaustive key search.
