Abstract

Methods, systems, and computer program products for building an encrypted document store are provided herein. A computer-implemented method includes building an encrypted ordered key-value store; encrypting one or more sensitive keys to be stored in the ordered key-value store using an order preserving encryption scheme; storing a state of the order preserving encryption scheme in the ordered key-value store; and encrypting one or more values corresponding to the one or more sensitive keys using a semantically secure encryption scheme.
