摘要
ACCESS数据库结构简。单、功能比较齐全、使用维护方便，因此，在功能能够满足要求的条件下，往往成为一些小型数据库软件的首选。但是由于数据库的加密机制非常简单，很容易破解数据库密码，安全性差。本文在分析了MSAccess数据库的加密原理以及现有破解方法的基础上，给出了简便易行的保护措施。并且，用VB给出了切实可行的实现方案。应用表明，该保护措施能有效地提高数据库的安全性。
MS Access database is a kind of widely used database due to its simple structure and easy maintenance. However, its weak key encryption caused some hacker software easily to get the database password. A method of protection is proposed based on the analysis of the tech nology of encryption and decryption, which is realized with VB. The practical application demonstrates that the method can improve security of MS Access database.
