Abstract:
Aspects of the invention include processing queries in a database system having a first database engine and a second database engine. A first instance of a first table is stored in the first database engine in plaintext. At one predefined column of the first table is encrypted, resulting in a set of encrypted columns, using a cascade encryption scheme that includes a set of ordered encryption methods. A subset of the set of columns is stored in a second instance of the first table in the second database engine. An encryption method of the cascade encryption scheme that allows a query operation of a received query on data encrypted with the identified encryption method is identified. The identified encryption method is used to rewrite the query, and the rewritten query is executed using the second instance of the first table.

Claim (Index 10):
The method of  claim 1 , wherein based at least in part on the query operation being an order operation, the identified encryption method is an order preserving encryption method.
