Homomorphic Encryption for Arithmetic of Approximate …

eprint.iacr.org

Keywords. 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

Somewhat Practical Fully Homomorphic Encryption

eprint.iacr.org

f(x) 2Z[x] is a monic irreducible polynomial of degree d. In practice one would typically restrict to using a cyclotomic polynomial m(x), i.e. the minimal polynomial of the primitive m-th roots of unity. The most popular choice for expository purposes is to take f(x) = xd+ 1 with d= 2n. Elements of the ring Rwill be denoted in lowercase bold, e ...

We call this composition operation universal composition and say that de nitions of security in this framework (and the protocols that satisfy them) are uni-versally composable (UC). Consequently, we dub this framework the UC security framework.1 As we shall see, the fact that security in this framework is preserved under universal composition ...
