Abstract
Fully homomorphic encryption (FHE) has been called the “Swiss Army knife of cryptography”, since it provides a single tool that can be uniformly applied to many cryptographic applications. In this tutorial we study FHE and describe its different properties, relations with other concepts in cryptography, and constructions. We briefly discuss the three generations of FHE constructions since Gentry’s breakthrough result in 2009, and cover in detail the third-generation scheme of Gentry, Sahai, and Waters (GSW).
