A Retrieve Model of WESU for Encrypted XML Database

To resolve the problems of poor security and low retrieve efficiency for XML DAS, a new retrieve model of WESU foe encrypted XML database is presented in this paper. It establishes the value index and structure index in the encrypted XML database, and executes the barrel management algorithm to record the entrance addresses in the value index and structure index. Through this model, the security of XML database and the retrieve efficiency are both improved.
