A construction method for security index based on data query in cloud computing
XING Wen-kai
Abstract：In order to enhance the security of data query in cloud computing and avoid the excessive access and data leakage in the process of user data query,a construction method for data security index at the cloud computing service side was proposed.The cloud computing data with graph deployment were constructed with the similar subgraph and Hash function,and the query objects and graph data were compared through the characteristic substructure to find the query objects.This method can prevent the graph data leakage of non query objects, and hash the Hash function to the nodes to improve the security of nodes.The results show that the method had high data query efficiency,low storage resource consumption and good security.
