Analysis and Improvement of BLP Model for Multi-Level Security Database

Abstract:

In the current multi-level security database system, the BLP model is the most widely used security model. For the problem of data redundancy, primary key loophole and reasoning channel of the BLP model, an improved method is proposed. The proposed method consummates the read-write level and the read-write range of user, increases the audit mechanism, eliminates the primary key loophole and avoids the reasoning channel to some extent. The proposed method in this paper improves the security of the BLP model and makes the security model more practical.
