The Hardness of LWE and Ring-LWE: A Survey. [PDF]
IACR Cryptol. ePrint Arch., 2021 The Learning with Errors (LWE) problem consists of distinguishing linear equations with noise from uniformly sampled values. LWE enjoys a hardness reduction from worst-case lattice problems, which are believed to be hard for classical and quantum ...

Practical CCA2-Secure and Masked Ring-LWE Implementation
Transactions on Cryptographic Hardware and Embedded Systems, 2018 During the last years public-key encryption schemes based on the hardness of ring-LWE have gained significant popularity. For real-world security applications assuming strong adversary models, a number of practical issues still need to be addressed.

Efficient Homomorphic Conversion Between (Ring) LWE Ciphertexts [PDF]
, 2021 In the past few years, significant progress on homomorphic encryption (HE) has been made toward both theory and practice. The most promising HE schemes are based on the hardness of the Learning With Errors (LWE) problem or its ring variant (RLWE). In this work, we present new conversion algorithms that switch between different (R)LWE-based HE schemes ...

Limits on the Efficiency of (Ring) LWE Based Non-interactive Key Exchange
Journal of Cryptology, 2020 Making non-interactive an interactive protocol, i.e. achieving the security goal in a single-round communication, is a common practice in the realm of public key cryptography. A practice that, at the time of writing, does not seem apply to key-exchange protocols based on the learning with errors problem (LWE), where all protocols are interactive.

Order-LWE and the Hardness of Ring-LWE with Entropic Secrets [PDF]
, 2019 We propose a generalization of the celebrated Ring Learning with Errors (RLWE) problem (Lyubashevsky, Peikert and Regev, Eurocrypt 2010, Eurocrypt 2013), wherein the ambient ring is not the ring of integers of a number field, but rather an order (a full rank subring).

Reduction From Module-SIS to Ring-SIS Under Norm Constraint of Ring-SIS
IEEE Access, 2020 Lattice-based cryptographic scheme is constructed based on hard problems on a lattice such as the short integer solution (SIS) problem and the learning with error (LWE).

Towards an efficient LWE‐based fully homomorphic encryption scheme
IET Information Security, 2022 The security of most early fully homomorphic encryption schemes was based on the hardness of the Learning with Errors (LWE) problem. These schemes were inefficient in terms of per gate computations and public‐key size.
