NettetAbstract. We present a new approach to the compression technique of Lyubashevsky et al. [17,13] for lattice-based signatures based on learning with errors (LWE). Our ideas seem to be particularly suitable for signature schemes whose security, in the random oracle model, is based on standard worst-case computational assumptions.

NettetOn Lattices, Learning with Errors, Random Linear Codes, and Cryptography Oded Regev ⁄ May 2, 2009 Abstract Our main result is a reduction from worst-case lattice problems such as GAPSVP and SIVP to a certain learning problem. This learning problem is a natural extension of the ‘learning from parity with error’ problem to higher … Nettet15. mai 2024 · This project proposes the use of plain lattices with learning with errors problem to implement a cryptographic scheme which can run on classical computers and provides security against quantum based attacks. We are proposing key sizes for efficient operations and implement a lattice trapdoor function. Also we will improve current … buzzfeed harvard best and worst courses

NettetIn cryptography, a public key exchange algorithm is a cryptographic algorithm which allows two parties to create and share a secret key, which they can use to encrypt messages between themselves. The ring learning with errors key exchange (RLWE-KEX) is one of a new class of public key exchange algorithms that are designed to be secure against … Nettet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 … Nettet12. jun. 2010 · The Learning with Errors Problem (Invited Survey) Abstract: In this survey we describe the Learning with Errors (LWE) problem, discuss its properties, its hardness, and its cryptographic applications.
