On the Security of Group Ring Learning with Errors [PDF]
IACR Communications in CryptologyWe propose a dimension-reducing transformation on Group Ring Learning with Errors (GRLWE) samples. We exhibit an efficiently computable isomorphism which takes samples defined over the group rings used in the construction of GRLWE to twice as many samples defined over matrix rings, in half the dimension.

Post-Quantum Key Exchange for the TLS Protocol from the Ring Learning with Errors Problem [PDF]
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 ...

Ring Signatures Based on Middle-Product Learning with Errors Problems
, 2019 Lattice-based (linkable) ring signatures are an important notion to cryptography since it protects signer anonymity against quantum computers. In this paper, we proposed a new lattice-based linkable ring signature scheme using a variant of Learning with Errors problem called Middle-Product Learning with Errors (\(\mathsf {MPLWE}\)). The proposed scheme

CIDER: Cyber‐Security in Industrial IoT Using Deep Learning and Ring Learning with Errors
IET Cyber-Physical SystemsTraditional security measures such as access control and authentication need to be more effective against ever‐evolving threats. Moreover, security concerns increase as more industries shift towards adopting the industrial Internet of things (IIoT ...

Quantum delegation from fully homomorphic encryption based on Ring learning with errors [PDF]
, 2021 Quantum computers will not likely be widespread and accessible to everyone in a foreseen future. Being capable of delegating quantum computation to untrusted parties while not losing condentiality would individuals to grant access to this technology. On the other hand, many current cryptography applications rely on the hardness of solving the discrete ...

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

Compact Ring Signatures from Learning With Errors [PDF]
, 2022 Ring signatures allow a user to sign a message on behalf of a ``ring\u27\u27 of signers, while hiding the true identity of the signer. As the degree of anonymity guaranteed by a ring signature is directly proportional to the size of the ring, an ...
