摘要： 虽然经过了多年的努力，但数据库安全的理论研究和具有安全特性的数据库产品仍然不能令人满意。文中首先介绍了数据库安全与操作系统安全、网络安全的不同点，然后讨论了当前数据库安全研究的几个领域，即安全数据库的语义、推理通道控制和安全的数据模型。最后提出了数据库安全研究应当解决的几个问题。

关键词: 数据库安全, 安全数据库的语义, 推理通道

Abstract: There are many aspects to have been desired on research in Database Security, at the same time, products of database with security properties we can see now do not meet the need. We first introduce in this paper the difference among Operation System Security, Network Security, and Database Security and then discuss three main areas for research in Database Security, that is, Semantics for Secure Database, Controlling Inference Channel, and Secure Data Model. Finally, the open problems on research in Dat abase Security are discussed.
