SEAL up your data just like Microsoft: Redmond open-sources 'simple' homomorphic encryption blueprints


The performance numbers you cite are not from this article and are unrelated to this work.

Homomorphic encryption has seen massive performance improvements over the past years. A single multiplication of such small numbers with SEAL would take around a millisecond. In an amortized setting the time would be closer to microsecond.

Search from O(billion) item data sets can be done with an encrypted query in seconds when done right. A complex SELECT-statement might be hard as SEAL at least is based on arithmetic circuits, whereas such queries may have much more convenient Boolean circuit representation.
