Abstract

Official abstract text for this publication.

Embodiments relate to processing encrypted data, and in particular to identifying an appropriate layer of encryption useful for processing a query. Such identification (also known as the onion selection problem) is achieved utilizing an adjustable onion encryption procedure. Based upon defined requirements of policy configuration, alternative resolution, and conflict resolution, the adjustable onion encryption procedure entails translating a query comprising an expression in a database language (e.g. SQL) into an equivalent query on encrypted data. The onion may be configured in almost arbitrary ways directing the onion selection. An execution function introduces an execution split to allow local (e.g. client-side) query fulfillment that may otherwise not be possible in a secure manner on the server-side. A searchable encryption function may also be employed, and embodiments accommodate aggregation via homomorphic encryption. Embodiments may be implemented as an in-memory column store database system.

First claim

Opening claim text (preview).

What is claimed is: 1. A computer-implemented method comprising: providing a database comprising encrypted plaintext; causing an engine to receive a first input comprising a database query including an expression; causing the engine to receive a second input comprising the plaintext encrypted according to a first encryption scheme; causing the engine to receive a third input comprising the plaintext encrypted according to a second encryption scheme; and causing the engine…
