摘要
为解决在边缘计算环境下多维数据的完整性验证问题,提出一种基于数据间邻居关系的完整性验证方法。该方法通过寻找数据项在多维空间各个象限的最佳近邻建立数据项间的邻居关系。经过加密的数据项和其邻居关系能够保证结果集的数据完整性。实验证明了该方法在多维数据完整性应用中的有效性。
To address the problem of completeness verification on multi-dimensional data in the applications of edge computing,this paper proposes a Neighborhood-Based Completeness Verification(NBCV) method.The solution creates the neighborhood of a data item by finding the nearest neighbor of the data item in each quadrant.The encrypted data items and their neighborhoods guarantee the completeness of the query results.Experimental shows that the proposed solution can be effectively applied in completeness verification of multi-dimensional data.
