DPUF: DPU-accelerated Near-storage Secure Filtering

Querying data stored in cloud object stores often leads to network bottlenecks, particularly when large datasets need to be transferred over wide area networks (WANs) for processing. Encryption further complicates this challenge by requiring entire encrypted objects to be fetched from the object store before analysis. To address this, we push down filtering and perform secure computing near storage using a Data Processing Unit (DPU) integrated into the cloud server.
