Inner product encryption from ring learning with errors [PDF]
Cybersecurity, 2020 The functional encryption scheme designed using the lattice can realize fine-grained encryption and it can resist quantum attacks. Unfortunately, the sizes of the keys and ciphertexts in cryptographic applications based on learning with errors are large,

Revisiting Multivariate Ring Learning with Errors and Its Applications on Lattice-Based Cryptography [PDF]
Mathematics, 2021 The “Multivariate Ring Learning with Errors” problem was presented as a generalization of Ring Learning with Errors (RLWE), introducing efficiency improvements with respect to the RLWE counterpart thanks to its multivariate structure.

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 ...

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

Using Ring Learning with Errors Problem to Construct Linkable Ring Signature Scheme
Jisuanji kexue yu tansuo, 2020 In order to solve the problem of large key size and low efficiency in the linkable ring signature scheme on lattice, this paper reconstructs the linkable ring signature scheme from lattice based on the ring learning with errors (RLWE) problem, according ...

Post-Quantum Key Exchange for the TLS Protocol from the Ring Learning with Errors Problem
2015 IEEE Symposium on Security and Privacy, 2015 Lattice-based cryptographic primitives are believed to offer resilience against attacks by quantum computers. We demonstrate the practicality of post-quantum key exchange by constructing cipher suites for the Transport Layer Security (TLS) protocol that provide key exchange based on the ring learning with errors (R-LWE) problem, we accompany these ...
