Popis:	The improvement of cryptogram query hit rate and the reduction of redundant data in query results are the challenges in the outsourced database (ODB) model. A synthetic encryption scheme applied to the ODB is presented to solve the problem of precise query over the cryptogram. This scheme employs encryption scheme on the attribute granularity, which combines a newly k-Mapping Character-data Encryption Scheme (k-MCES) with the existing Order Preserving Encryption Scheme (OPES). The theories and experiments analysis show that queries over encrypted data with this synthetic encryption scheme can return exact results. Furthermore, this scheme is correct and safe.
