Non-commutative Ring Learning with Errors from Cyclic Algebras
Journal of Cryptology, 2022 AbstractThe Learning with Errors (LWE) problem is the fundamental backbone of modern lattice-based cryptography, allowing one to establish cryptography on the hardness of well-studied computational problems. However, schemes based on LWE are often impractical, so Ring LWE was introduced as a form of ‘structured’ LWE, trading off a hard to quantify loss

IEEE Access, 2023 A three-party authenticated key exchange protocol enables two entities to agree on a session key with the help of a dedicated server over a public channel. Shor’s algorithm is a big threat to existing authenticated key exchange protocols.

Multiparty Homomorphic Encryption from Ring-Learning-with-Errors [PDF]
Proceedings on Privacy Enhancing Technologies, 2021 Abstract We propose and evaluate a secure-multiparty-computation (MPC) solution in the semi-honest model with dishonest majority that is based on multiparty homomorphic encryption (MHE). To support our solution, we introduce a multiparty version of the Brakerski-Fan-Vercauteren homomorphic cryptosystem and implement it in an open-source ...

Fast Vector Oblivious Linear Evaluation from Ring Learning with Errors [PDF]
Proceedings of the 9th on Workshop on Encrypted Computing & Applied Homomorphic Cryptography, 2021 Oblivious linear evaluation (OLE) is a fundamental building block in multi-party computation protocols. In OLE, a sender holds a description of an affine function $f_α,β (z)=α z+β$, the receiver holds an input x, and gets α x+β$ (where all computations are done over some field, or more generally, a ring). Vector OLE (VOLE) is a generalization where the

Ring Signature With Unconditional Anonymity in the Plain Model
IEEE Access, 2021 Ring signature allows a user to sign messages as a member of a set of users, which is called the ring. In addition to an unforgeability, ring signature ensures that nobody can detect which member in the ring signs the message.

Highly Efficient Architecture of NewHope-NIST on FPGA using Low-Complexity NTT/INTT
Transactions on Cryptographic Hardware and Embedded Systems, 2020 NewHope-NIST is a promising ring learning with errors (RLWE)-based postquantum cryptography (PQC) for key encapsulation mechanisms. The performance on the field-programmable gate array (FPGA) affects the applicability of NewHope-NIST.

Ring-LWE Cryptography for the Number Theorist [PDF]
, 2015 In this paper, we survey the status of attacks on the ring and polynomial learning with errors problems (RLWE and PLWE). Recent work on the security of these problems [Eisentr\"ager-Hallgren-Lauter, Elias-Lauter-Ozman-Stange] gives rise to interesting ...

ARTMAP: Supervised Real-Time Learning and Classification of Nonstationary Data by a Self-Organizing Neural Network [PDF]
, 1991 This article introduces a new neural network architecture, called ARTMAP, that autonomously learns to classify arbitrarily many, arbitrarily ordered vectors into recognition categories based on predictive success. This supervised learning system is built

Security considerations for Galois non-dual RLWE families [PDF]
, 2017 We explore further the hardness of the non-dual discrete variant of the Ring-LWE problem for various number rings, give improved attacks for certain rings satisfying some additional assumptions, construct a new family of vulnerable Galois number fields ...
