Estimation of the hardness of the learning with errors problem with a restricted number of samples

open access: yesJournal of Mathematical Cryptology, 2019
The Learning With Errors (LWE) problem is one of the most important hardness assumptions lattice-based constructions base their security on. In 2015, Albrecht, Player and Scott presented the software tool LWE-Estimator to estimate the hardness of ...

Reduction From Module-SIS to Ring-SIS Under Norm Constraint of Ring-SIS

open access: yesIEEE 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).

A detailed analysis of the hybrid lattice-reduction and meet-in-the-middle attack

open access: yesJournal of Mathematical Cryptology, 2019
Over the past decade, the hybrid lattice-reduction and meet-in-the middle attack (called hybrid attack) has been used to evaluate the security of many lattice-based cryptographic schemes such as NTRU, NTRU Prime, BLISS and more.

Succinct LWE Sampling, Random Polynomials, and Obfuscation [PDF]

open access: yes, 2021
We present a construction of indistinguishability obfuscation (iO) that relies on the learning with errors (LWE) assumption together with a new notion of succinctly sampling pseudo-random LWE samples.

Lattice Trapdoors and IBE from Middle-Product LWE [PDF]

open access: yes, 2021
© 2019, International Association for Cryptologic Research. Middle-product learning with errors (MP-LWE) was recently introduced by Rosca, Sakzad, Steinfeld and Stehlé (CRYPTO 2017) as a way to combine the efficiency of Ring-LWE with the more robust ...

On the Ring-LWE and Polynomial-LWE Problems

open access: yes, 2018
The Ring Learning With Errors problem (\(\mathsf {RLWE}\)) comes in various forms. Vanilla \(\mathsf {RLWE}\) is the decision dual-\(\mathsf {RLWE}\) variant, consisting in distinguishing from uniform a distribution depending on a secret belonging to the dual \(\mathcal {O}_K^{\vee }\) of the ring of integers \(\mathcal {O}_K\) of a specified number ...

Quantum Key Search for Ternary LWE [PDF]

open access: yes, 2021
Ternary LWE, i.e., LWE with coefficients of the secret and the error vectors taken from $\{-1, 0, 1\}$, is a popular choice among NTRU-type cryptosystems and some signatures schemes like BLISS and GLP.

A Toolkit for Ring-LWE Cryptography [PDF]

open access: yes, 2013
Recent advances in lattice cryptography, mainly stemming from the development of ring-based primitives such as ring-LWE, have made it possible to design cryptographic schemes whose efficiency is competitive with that of more traditional number-theoretic ones, along with entirely new applications like fully homomorphic encryption.

Packed Ciphertexts in LWE-Based Homomorphic Encryption [PDF]

open access: yes, 2012
In this short note we observe that the Peikert-Vaikuntanathan-Waters (PVW) method of packing many plaintext elements in a single Regev-type ciphertext, can be used for performing SIMD homomorphic operations on packed ciphertext.

Achieving broadband directivity control with dual corona discharge transducers

open access: yesActa Acustica
Loudspeakers inherit their directivity from their geometry and dimensions. Enclosed loudspeakers are omnidirectional in the low frequency range, but their directivity depends on frequency for wavelengths smaller than the radiator size, precluding the ...
