Private Equality Test Using Ring-LWE Somewhat Homomorphic Encryption

2016 3rd Asia-Pacific World Congress on Computer Science and Engineering (APWC on CSE), 2016
We propose two secure protocols namely private equality test (PET) for single comparison and private batch equality test (PriBET) for batch comparisons of l-bit integers. We ensure the security of these secure protocols using somewhat homomorphic encryption (SwHE) based on ring learning with errors (ring-LWE) problem in the semi-honest model.

How (Not) to Instantiate Ring-LWE

2016
The learning with errors over rings Ring-LWE problem--or more accurately, family of problems--has emerged as a promising foundation for cryptography due to its practical efficiency, conjectured quantum resistance, and provable worst-case hardness: breaking certain instantiations of Ring-LWE is at least as hard as quantumly approximating the Shortest ...

A New Secure Matrix Multiplication from Ring-LWE

2018
Matrix multiplication is one of the most basic and useful operations in statistical calculations and machine learning. When the matrices contain sensitive information and the computation has to be carried out in an insecure environment, such as a cloud server, secure matrix multiplication computation (MMC) is required, so that the computation can be ...

Integer Version of Ring-LWE and Its Applications

2019
In this work, we introduce an integer version of ring-LWE (I-RLWE) over the polynomial rings and present a public key encryption based on I-RLWE. The security of our scheme relies on the computational hardness assumption of the I-RLWE problem.

Cryptography with the Ring-LWE (Learning With Errors) Algorithm

Jurnal Teknik Indonesia
Ring-LWE (Ring Learning With Errors) is a post-quantum cryptography algorithm based on mathematical problems in number theory and algebra. It is an extension of LWE (Learning With Errors) first introduced by Oded Regev and is used for secure data encryption from quantum computer attacks.
