摘要: There are many incentives for healthcare providers to shift their datacenters the cloud. However, privacy of patient health information is a major concern when processing medical data off-site. One possible solution use Fully Homomorphic Encryption (FHE), but this too slow most applications. We present technique that increases efficiency and parallelism certain algorithms under FHE. Through simulations, we demonstrate our method yields about 20x speedup in sample application. This significant step towards practical FHE-based remote monitoring.
