Abstract
The present invention relates to a system and a method for multidimensional range searching for encrypted data, and an apparatus for the same. A method for multidimensional range searching for encrypted data according to an aspect of the present invention may include: generating an order revealing encryption (ORE) index table for a plurality of record data, wherein each of the plurality of record data includes data for a plurality of attributes; receiving a query for multidimensional range searching for the first attribute and the second attribute for the plurality of record data; determining one or more ORE indexes that satisfies all of the multidimensional range in the ORE index table for any one of the first attribute and the second attribute; and determining a response to the query based on the one or more ORE indexes.
