QFilter: Towards a Fine-Grained Access Control for Aggregation Query Processing over Secret Shared Data.

Kurzbeschreibung (Abstract)

This paper presents QFilter, a privacy-preserving and communication efficient solution that integrates an Attribute-Based Access Control (ABAC) model into query processing. QFilter enables the specification and enforcement of fine-grained access control policies tailored to secret-shared data. It can process aggregation SQL queries, including” count”,” sum”, and” avg” functions, with both conjunctive (using” AND”) and disjunctive (using” OR”) equality query conditions, without the need for inter-server communication. QFilter is secure against honest-but-curious adversaries, and the preliminary experiments illustrate its applicability for preserving privacy in query processing over secret-shared data, especially at the tuple level access control with the lowest overhead.
