Learning with Errors In subject area: Computer Science Learning with Errors (LWE) is defined as a cryptographic problem where, given multiple samples from a specific distribution, it is hard to recover the orig

本综述中,我们描述了带错误的学习 (LWE) 问题,讨论了它的性质、困难性及其密码应用。 关键词:错误学习;格密码 一、引言 近年来,[Reg05] 中引入的带错误学习 (LWE) 问题,已被证明是密码构造的通用基础。 它主要名声来自于与最坏情况的格问题一样困难,因此在最坏情况的格问题困难性的假设下,使所有基于它的密...
我们终于在Lecture 03遇到了格密码学之所以在近15年来蓬勃发展,最关键的安全假设:Learning With Errors(LWE)。Lecture 03主讲人Chirs Peikert是格密码学非常重要的研究人员。Lecture 03仍然分为两个部分,第1部分主要讲解LWE假设本身,第2部分讲解用Learning With Round(LWR)假设和LWE假设构建可证明安全伪随机函数(...
Learningproblemquantum samplesThe learning-with-errors (LWE) problem is one of the fundamental problems in computational learning theory and has in the last years become the cornerstone of postquantum cryptography. In this work, we study the quantum sample complexity of learning with errors and show...

We introduce a new class of intractability problems, called Learning with Errors in the Exponent (LWEE). We give a tight reduction from Learning with Errors (LWE) and the Representation Problem (RP) in finite groups, two seemingly unrelated problem, to LWEE. The argument holds in the ...
1.1 Previous FHE Schemes Based on Learning with Errors Currently, perhaps the simplest leveled 1 FHE scheme based on the learning with errors (LWE) assumption [Reg05] is by Brakerski [Bra12]. In fact, Barak and Brakerski do give a remarkably ...

On Lattices, Learning with Errors, Random Linear Codes, and Cryptography Oded Regev September 8, 2007 Abstract Our main result is a reduction from worst-case lattice problems such as SVP and SIVP to a certain learning problem. This learning problem is a natural extension of the ‘learning from...
