Research of security mechanisms based on LogicSQL database

LogicSQL is an object relational database management system implemented with the advanced (formula-lock based) concurrency control protocol, and the steged database architecture. It is independently developed based on the Linux high-level security database system. Ministry of Science and Technology "863" Database Group of the major projects comments LogicSQL database "It is the only hope that China's database products will be able to contend with America's mainstream database products in the next few years." Access control policies are security policies that govern access to resources. It can be applied to several new types of databases. In this paper, we discuss access control in multilevel database management systems applies and illustrate the main applies of security mechanisms in the LogicSQL database system.
