Optimized and controlled provisioning of encrypted outsourced data

Abstract : Recent advances in encrypted outsourced databases support the direct processing of queries on encrypted data. Depending on functionality (i.e. operators) required in the queries the database has to use different encryption schemes with different security properties. Next to these functional requirements a security administrator may have to address security policies that may equally determine the used encryption schemes. We present an algorithm and tool set that determines an optimal balance between security and functionality as well as helps to identify and resolve possible conflicts. We test our solution on a database benchmark and business-driven security policies.
