面向标记安全数据库的Skyline立方体算法
Label security database-oriented Skyline cube algorithm
摘要
Abstract
To improve the data security and response speed of Skyline query, a label Skyline cube concept was proposed, which was oriented label security database and compliance with read access rules of mandatory access control. The label Skyline cube was a collection of all Skyline query results of users with different labels and each of the Skyline queries coming from users with different user labels could be quickly responded by using the pre-computed cube. An algorithm based on the sharing strategy was proposed to compute the label Skyline cube efficiently. This algorithm is optimized according to the properties of the Skyline and label. In the algorithm, the containment relationship of point set derived from domination relationship of labels is used and the calculations are shared by iteration, avoiding the low efficiency caused by calculating each Skyline of the cube independently.关键词
