High-Throughput Ring-LWE Cryptoprocessors

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2017
This paper presents the design of ring learning with errors (LWE) cryptoprocessors using number theoretic transform (NTT) cores and Gaussian samplers based on the inverse transform method. The NTT cores are designed using radix-2 and radix-8 decimation-in-frequency NTT algorithms and pipeline architectures.

Cryptanalysis of Compact-LWE

2018
As an invited speaker of the ACISP 2017 conference, Dongxi Liu recently introduced a new lattice-based encryption scheme (joint work with Li, Kim and Nepal) designed for lightweight IoT applications. The new scheme, which has been submitted to the NIST post-quantum competition, is based on a variant of standard LWE called Compact-LWE, but is claimed to

Lossiness and Entropic Hardness for Ring-LWE

2020
The hardness of the Ring Learning with Errors problem (RLWE) is a central building block for efficiency-oriented lattice-based cryptography. Many applications use an “entropic” variant of the problem where the so-called “secret” is not distributed uniformly as prescribed but instead comes from some distribution with sufficient min-entropy. However, the

Reusable Fuzzy Extractor from LWE

2018
Fuzzy extractor converts the reading of a noisy non-uniform source to a reproducible and almost uniform output \(\mathsf {R}\). The output \(\mathsf {R}\) in turn is used in some cryptographic system as a secret key. To enable multiple extractions of keys \(\mathsf {R}_1, \mathsf {R}_2, \ldots , \mathsf {R}_\rho \) from the same noisy non-uniform ...
