FHE allows computation of still-encrypted data, without sharing the secrets.

Yesterday, Ars spoke with IBM Senior Research Scientist Flavio Bergamaschi about the company’s recent successful field trials of Fully Homomorphic Encryption. We suspect many of you will have the same questions that we did—beginning with “what is Fully Homomorphic Encryption?”

FHE is a type of encryption that allows direct mathematical operations on the encrypted data. Upon decryption, the results will be correct. 

…You don’t ever have to share a key with the third party doing the computation; the data remains encrypted with a key the third party never received. Read More
