SAGMA: Secure Aggregation Grouped by Multiple Attributes

Summary: SAGMA enables secure aggregation over outsourced data with GROUP BY, supporting arbitrary grouping attributes and protecting cloud ciphertexts semantically. It hides access patterns and group frequencies to curb leakage; evaluation shows feasibility. (summarized by gpt-5-nano on Feb 09 2026)
