Research on Identifying Method of Covert Channels in Database System

At present, the security level of DBMS in our country fails to satisfy the need of development and it's an urgent task to improve the safety performance of the relational database systems. The analysis and research on covert channels are vital to raising the security level of DBMS in our county. In this paper, we study the identifying method of covert channels in database system and propose a more efficient, more authentic and safely isolated identifying method of covert channels, which contributes to the follow-up process. © Springer-Verlag Berlin Heidelberg 2013.
