ENHANCEMENTS STRATEGY OF CLOUD STORAGE ACCESS CONTROL APPLIED TO POWER GRID ENTERPRISE
摘要
Abstract
For the security need of cloud storage applications in power information management,we propose an enhancement strategy of cloud storage access control,which is based on the combination of entity attributes and security tag,and is targeted at reducing the system overhead of conventional access control schemes in regard to access rules. The strategy utilises entity attributes-oriented privileges management method to optimise the access control,reduces privileges management overhead,and prevents the direct contacts between the access privileges and the user,storage process and platform object.Moreover,it also uses multi-level security tag to carry out privileges allocation and to ensure the flexibility of the strategy in maintenance when implemented.A power information cloud storage management system at a certain power grid enterprises is taken for example to elaborate the specific configuration process of the strategy.It is illustrated by the performance analysis that the access control strategy designed in the paper has good performance in maintainability,storage overhead, security and other aspects,and has application feasibility.关键词
