Secure Cloud Data Processing with Fully Homomorphic Encryption

Abstract

Fully homomorphic encryption (FHE) has been named
the sacred goal of cryptography, a subtle objective that could
tackle the IT world's concerns of safety and trust. Research in
the space detonated after 2009 when Craig Gentry showed that
FHE can be acknowledged on a fundamental level. Since that
time impressive advancement has been made in seeing as more
viable and more effective arrangements. While the research was
immediately created, wording and ideas became assorted and
befuddling with the goal that today, it might be difficult to
determine the successes of diverse works. The ultimate goal of
this paper is to answer three critical questions. What is FHE?
How FHE ensures security? How FHE can be implemented on
cloud? Just as reviewing the field, we explain distinctive
phrasing being used and demonstrate associations between
various FHE ideas.
