The database-as-a-service DAS model is a newly emerging computing paradigm,where the DBMS functions are outsourced. It is desirable to store data on databaseservers in encrypted form to reduce security and privacy risks since the server may notbe fully trusted. But this usually implies that one has to sacrifice functionality andefficiency for security. Several approaches have been proposed in recent literaturefor efficiently supporting queries on encrypted databases. These approaches differfrom each other in how the index of attribute values is created. Random one-to-onemapping and order-preserving are two examples. In this paper we will adapt a prefix-preserving encryption scheme to create the index. Certainly, all these approaches lookfor a convenient trade-off between efficiency and security. In this paper we will discussthe security issues and efficiency of these approaches for supporting range queries onencrypted numeric data.
