摘要:

经典密码学是一种在没有计算机的时候掩盖人们所做的新闻的方法。目的是通过编码的方式保护信息。本文介绍了一种改进的经典算法,使cryptanalis难以窃取未公开的消息。经典的Chiper算法有仿射Chiper、Caesar Chiper和Chiper转置三种。其中对于chiperteks,仿射chiper和凯撒chiper可以像初始密钥一样循环,因为结果可以像密钥值一样变化,那么仿射chiper和凯撒chiper在这种情况下是动态的。然后将仿射和Caesar的结果结合到转置Chiper矩阵中,应用水稻栽培路径模式,最后应用水稻种植路径模式进行Chipertext检索,并对以二进制数字形式表示的数字的最后一位进行置乱,使得5个字符可以变为80位比特。因此,密码分析师将更加困难,需要很长时间才能破解一直保密的信息。

英文摘要:

Classical cryptography is a way of disguising the news done by the people when there was no computer. The goal is to protect information by way of encoding. This paper describesa modification of classical algorithms to make cryptanalis difficult to steal undisclosed messages. There are three types of classical algorithms that are combined affine chiper, Caesar chiper and chiper transposition. Where for chiperteks affine chiper and Caesar chiper can be looped as much as the initial key, because the result can be varied as much as key value, then affine chiper and Caesar chiper in this case is dynamic. Then the results of the affine and Caesar will be combined in the transposition chiper matrix by applying the pattern of rice cultivation path and for chipertext retrieval by finally applying the pattern of rice planting path. And the final digit of the digit shown in the form of binary digits so that 5 characters can be changed to 80 digit bits are scrambled. Thus the cryptanalyst will be more difficult and takes a very long time to hack information that has been kept secret.
