摘要:   本研究的目的是要找寻一个改进奚尔密码法(Hill Cipher)的方法,
使得系统能有更好的安全防护能力,我们希望这种改进方法能保留奚尔密
码法中设计简单且计算容易的特点,当然它也要能够抵抗选择明文攻击
法(Chosen-Plaintext Attack)的攻击;我们也希望这种方法能被广泛地
接受和应用于个人资料的保密、网路传递资料的保密及各种适合使用私用
金匙密码法的应用上。 在本研究中,我们从期刊、书籍及会议记录中
,收集了有关奚尔密码法的文献,从这些文献中,我们归纳出改进奚尔密
码法的三种基本方法;另外,我们也提出了一种改进的方法并且证明了我
们所提出的改进方法,确实能够有效地使奚尔密码法有更好的安全防护能
力;最后,我们也对这些方法做一个简单的比较。
The purpose of our research is that we will find an improved
Hill Cipher which has a better protection. This scheme, of
course,can keep the characteristics of the Hill Cipher and can
prevent the Chosen-Plaintext Attack. We also hope that this
scheme can be widely accepted and applied for protecting
private data, data transmitting on the network, or any
application the private key cryptography can apply. In this
paper,we collect the relative papers from journals, books, and
conference papers. From these papers, we categorize three basic
methods related to improve Hill Cipher. We propose an improved
method to promise the degree of security. Finally, we compare
these methods.
