用Hill加密法对密码存储安全性的改进

An Improvement for Encrypted Password Storage′s Safety with the Use of Hill Cipher

计算机中大量以密文形式存储的内容,可以用很多现有的加密算法反查表把其密码破解出来.因为只要拿到了密文,破译者就能够根据反查表比对出一些常用加密算法所对应的明文.对此,本文提出了一种改进方法,先对这些明文进行Hill改进算法加密,然后再进行加密存储.实验证明该方法可以有效地增强系统的安全性.

In the computer, there are a lot of contents stored by password form, their cryptogram is often easily to be cracked by using many anti-encryption algorithm look-up table. As long as hackers obtain the encrypted password, they can easily get the original password according to above table. To address this issue, the paper presents an improved method. Encrypting the original password through improved-Hill encryption firstly, then storing. Results show that the method can effectively increase the security of the system.
