secure range query processing algorithms have been studied as the rangequery can be used as a baseline technique in various fields. However, when processing a rangequery, the existing methods fail to hide the data access patterns which can be used to derive the actual data items and the private information of a querying issuer. The problem is that the data access patterns can be exposed even though the data and query are encrypted. So, in this paper we propose a new rangequeryprocessing algorithm on the encrypted database. Our method conceals the data access patterns while supporting efficient queryprocessing by using our proposed encrypted index search scheme. Through the performance analysis, we show that the proposed rangequeryprocessing algorithm can efficiently process a query while hiding the data access patterns.
