摘要
在现实生活中,一些数据库资料是需要保密的,如专业机构的会员数据库。专业机构的会员数据库颇有商业价值,通常由专业机构所掌握。如何保护会员数据库使之不为外人所用是专业机构的一项重要工作,而密码学就能够完成保护会员数据库的工作。本文基于密码学提出了两种数据库密码保护的方案。
In actual life, we know some database information need to be protected, such as the number databases of a special organization. The member databases of a special organization has very important commercial values, and it is usually controlled by the special organization. It is a very important job to prevent the member databases from being stolen by other organizations. Cryptography can complete the job to protect the member databases. In this paper, we propose two kinds of database protection schemes based on cryptography.
