Enhancing Ring-LWE Hardness using Dedekind Index Theorem [PDF]
, 2023 In this work we extend the known pseudorandomness of Ring-LWE (RLWE) to be based on ideal lattices of non Dedekind domains. In earlier works of Lyubashevsky et al (EUROCRYPT 2010) and Peikert et al (STOC 2017), the hardness of RLWE was based on ideal ...

Compact Ring-LWE based Cryptoprocessor
, 2014 In this paper we propose an efficient and compact processor for a ring-LWE based encryption scheme. We present three optimizations for the Number Theoretic Transform (NTT) used for polynomial multiplication: we avoid pre-processing in the negative ...
