Unless the database is also encrypted and provides the same homomorphism against reverse index queries.

Unless the database is also encrypted and provides the same homomorphism against reverse index queries.
- soberhoff 8y agoIf the database was encrypted, you would need a different encrypted database for every user - again impractical.
- betterunix2 8y agoIn which case you are no longer talking about FHE. With FHE the server receives a ciphertext query and produces a ciphertext output, without ever seeing any plaintexts (not even the result of a reverse index query).
