EncDBDB: Searchable Encrypted, Fast, Compressed, In-Memory Database using Enclaves [article]

Benny Fuhry SAP Security Research
2020 arXiv   pre-print
We present EncDBDB, a novel approach for client-controlled encryption of a column-oriented, in-memory databases allowing range searches using an enclave.  ...  Existing solutions are not optimized for column-oriented, in-memory databases and pose impractical memory requirements on the enclave.  ...  High compression rates achieved by dictionary encoding sparingly use the scarce resource of in-memory databases -main memory.  ...
