Abstract
The techniques discussed herein facilitate the transmission, storage, and manipulation of data in an encrypted database management system (EDBMS). An untrusted machine is connected to a data store having encrypted records, a client machine that sends encrypted queries, and a trusted machine that receives and decrypts the encrypted records and encrypted queries. The trusted machine processes the query using semantically secure query operators to produce a query result. The trusted machine ensures the size of the query result conforms to an upper bound on the number or records in the query result and returns the query result.
