Efficient Encrypted Storage Structure for Prevention Of Information Leakage

摘要

The security of database is more and more concerned. There are several traditional methods to protect the information of databases, such as encryption and authentication. However, these methods are not appropriate for all the situations because of the performance. This paper proposed a new method to prevent the information leakage of traditional databases, and this idea is totally different from the traditional ones. We can change the semantic meanings of relational data by reordering them. By this way, we can prevent the information from leakage. Some users with low privileges will only get the meaningless data, while they do not realize that themselves. In many cases, this method meets the requirements of security while it influences a little on the system performance.
