Lattice Decoding Attacks on Binary LWE

, 2014
. We consider the binary-LWE problem, which is the learn-ing with errors problem when the entries of the secret vector are chosen from {0, 1} or {−1, 0, 1} (and the error vector is sampled from a discrete Gaussian distribution).

Modulus Switching in LWE

, 2022
The Learning With Errors problem is the basis of a few cryptosystems, and a foundation for many fully homomorphic encryption (FHE) schemes. In this article I'll describe a technique used in some of these schemes called modulus switching. In brief, an LWE sample is a vector of values in $\mathbb{Z}/q\mathbb{Z}$ for some $q$, and in LWE cryptosystems an ...

Cold Boot Attacks on Ring and Module LWE Keys Under the NTT

Transactions on Cryptographic Hardware and Embedded Systems, 2018
In this work, we consider the ring- and module- variants of the LWE problem and investigate cold boot attacks on cryptographic schemes based on these problems, wherein an attacker is faced with the problem of recovering a scheme’s secret key from a noisy

Key Switching in LWE

, 2022
Last time we covered an operation in the LWE encryption scheme called modulus switching, which allows one to switch from one modulus to another, at the cost of introducing a small amount of extra noise, roughly $\sqrt{n}$, where $n$ is the dimension of the LWE ciphertext.

Investigating the Effect of Reducing the Signs and Symptoms of Lid Wiper Epitheliopathy in Patients With Dry Eye Disease With Perfluorohexyloctane

Current Therapeutic Research
: Background: Perfluorohexyloctane (PFHO) acts to prevent the evaporation of the tear film. It has the potential to limit friction related issues between the eye lid margin and the ocular surface.

Practical MP-LWE-based encryption balancing security-risk vs. efficiency [PDF]

, 2019
Middle-Product Learning With Errors (MP-LWE) is a variant of the LWE problem introduced at CRYPTO 2017 by Rosca et al [RSSS17]. Asymptotically, the theoretical results of [RSSS17] suggest that MP-LWE gives lattice-based public-key cryptosystems offering ...
