Research on Index Scheme of Encrypted XML Data Structure

摘要

This paper proposed a B+ tree encrypted XML structure index scheme and further discussed a query model using Dewey coding. In the process of XML document encryption, the XML encrypted data is stored together with the B+ tree index based on the encrypted data on the server-side, to complete the structural index of the encrypted data on the server-side. This method improves the efficiency of the query and effectively achieves the structural index of encrypted XML data.
