Research on database controlled memory authorization application model based on ARM architecture

The traditional database authorization application model uses forward and generalized authorization rules to authorize the database, which requires all authorization items to be examined in turn when authorizing, and the authorization granularity is too coarse, leading to a large amount of data redundancy in the authorization library and the complexity of the authorization library is increased. To address the above problems, the application model of controlled memory authorization for database based on ARM architecture will be studied. After database semantic view reconstruction in ARM architecture virtualization platform, the distribution of data controllable memory authorization rules is determined. The database memory authorization information is encrypted and managed using the NTRU algorithm, and the database controlled memory authorization application model is constructed and implemented on the basis of the RBAC access control model. The simulation experimental results show that the authorization model studied has an authorization card redundancy ratio lower than 8%, which is much smaller than the traditional authorization model, and the authorization granularity of this authorization model is small, which can effectively ensure the database security.
