Somewhat Practical Fully Homomorphic Encryption
Fully homomorphic encryption (FHE) allows evaluation of arbitrary functions on encrypted data, and as such has a myriad of potential applications such as private cloud computing. Gentry [7,8] was the rst to show that FHE is theoretically possible. His construction consisted of three parts: rst, construct an encryption scheme that is

Homomorphic Encryption for Arithmetic of Approximate …
eprint.iacr.orgKeywords. Homomorphic encryption, approximate arithmetic 1 Introduction Homomorphic encryption (HE) is a cryptographic scheme that enables homomorphic oper-ations on encrypted data without decryption. Many of HE schemes (e.g. [18, 6, 7, 4, 5, 25, 33, 2, 26, 13, 12, 21, 19]) have been suggested following Gentry’s blueprint [23]. HE can be
