Summary

The paper proposes AHEDB, a scheme for speeding up aggregation queries over homomorphically encrypted databases. It uses Encrypted Multiple Maps (EMM) to reduce the homomorphic computation load and adds a Single Range Cover (SRC) algorithm for range and equality indexing. The authors report that their experiments show lower querying overheads than an FHE-based database system while balancing security and efficiency.
