Improved Multiplication Triple Generation over Rings via SHE
Secure Two-party Computation Beaver Multiplication Triples Somewhat Homomorphic Encryption
2019/5/29
An important characteristic of recent MPC protocols is an input independent preprocessing phase in which most computations are offloaded, which greatly reduces the execution overhead of the online pha...
The purpose of this paper is to investigate fixed point arithmetic
in ring-based Somewhat Homomorphic Encryption (SHE) schemes.
We provide three main contributions: Firstly, we investigate the repre...
We present a multi-party computation protocol in the case
of dishonest majority which has very low round complexity. Our protocol
sits philosophically between Gentry’s Fully Homomorphic Encryption
...
High-speed Polynomial Multiplication Architecture for Ring-LWE and SHE Cryptosystems
Cryptography Polynomial multiplication Number theoretic transform (NTT)
2016/1/7
Polynomial multiplication is the basic and most computationally intensive operation in ring-Learning With Errors (ring-LWE) encryption and ``Somewhat" Homomorphic Encryption (SHE) cryptosystems. In th...
