Data Access Control

Property of transmission system will directly influence the performance and reliability of helicopters. Information exchange and sharing are difficult in transmission system life-cycle, which has complex product to fabricate and mass information to handle. To solve this problem, we establish a unified product data (UPD) to manage the information of research-development process for transmission system. In distributed collaborative environment, a single enterprise UPD is established by analysing transmission system development process and data flow. The theoretical frame of UPD and several key techniques are studied, including architecture, model, management, consistency, and mapping of data access control. Data integration and data access control model in development process is discussed in this paper. A UPD integration framework based on collaborative agent is presented, which shows the evolvement theory among PUPD, DUPD, SUPD and IUPD. Besides, task-role-based access control model is proposed, and dynamic right control process is given for UPD.

The professionalism and complexity of medical big data and the expensiveness of acquiring medical knowledge make it difficult for policymakers to judge whether the information accessed by doctors is necessary from a professional perspective and to formulate accurate access control strategies. To solve the above problems, this paper proposes a T-RBAC (trust-role based access control) model based on two-dimensional dynamic trust assessment, Using AHP and Grey theory to quantify the role attribute trust in the dimension of the doctor’s own attributes, Using Euler’s measurement method and probability statistics to quantify doctors’ behavioral trust in the dimension of historical behavior, then, the trust rule base performs hierarchical authorization based on the comprehensive trust value obtained by the weighted average. Multiattribute trust comprehensive evaluation makes the access control model have finer access granularity and higher security. At the same time, the introduction of time decay function and penalty function enhances the model’s sensitivity, dynamics, and resistance to bleaching attacks.
