Homomorphic Encryption 101: The Holy Grail of Cryptography

Interesting analysis on the current state of the art for FHE:

"Fully Homomorphic Encryption (FHE) has long been considered as the holy grail of cryptography. The concept was imagined in the late seventies, but the first realization only came three decades later. Today, both the public and private sectors are embracing this new security paradigm and are actively working at making FHE more practical and easier to use."
