Abstract

Methods, systems, and computer-readable storage media for processing queries in analytical web applications over encrypted data. Implementations include actions of receiving, by a database driver executed on a server-side computing device and from a client-side proxy, a query and one or more encryption keys, the one or more encryption keys having been selected by the client-side proxy based on operations required to perform the query, performing at least one operation of the query to provide a query result including encrypted data, and transmitting, by the database driver, the encrypted data to the client-side proxy, the client-side proxy processing the encrypted data to provide plaintext data to an end user.
