On the Ring-LWE and Polynomial-LWE Problems

, 2018
The Ring Learning With Errors problem (\(\mathsf {RLWE}\)) comes in various forms. Vanilla \(\mathsf {RLWE}\) is the decision dual-\(\mathsf {RLWE}\) variant, consisting in distinguishing from uniform a distribution depending on a secret belonging to the dual \(\mathcal {O}_K^{\vee }\) of the ring of integers \(\mathcal {O}_K\) of a specified number ...

Achieving broadband directivity control with dual corona discharge transducers

Acta Acustica
Loudspeakers inherit their directivity from their geometry and dimensions. Enclosed loudspeakers are omnidirectional in the low frequency range, but their directivity depends on frequency for wavelengths smaller than the radiator size, precluding the ...

Learning with Errors is easy with quantum samples

, 2018
Learning with Errors is one of the fundamental problems in computational learning theory and has in the last years become the cornerstone of post-quantum cryptography.

Classical Homomorphic Encryption for Quantum Circuits [PDF]

, 2018
We present the first leveled fully homomorphic encryption scheme for quantum circuits with classical keys. The scheme allows a classical client to blindly delegate a quantum computation to a quantum server: an honest server is able to run the computation

Adhesion of membranes via receptor-ligand complexes: Domain formation, binding cooperativity, and active processes [PDF]

, 2009
Cell membranes interact via anchored receptor and ligand molecules. Central questions on cell adhesion concern the binding affinity of these membrane-anchored molecules, the mechanisms leading to the receptor-ligand domains observed during adhesion, and ...

Compact Ring-LWE Cryptoprocessor [PDF]

, 2014
In this paper we propose an efficient and compact processor for a ring-LWE based encryption scheme. We present three optimizations for the Number Theoretic Transform NTT used for polynomial multiplication: we avoid pre-processing in the negative wrapped convolution by merging it with the main algorithm, we reduce the fixed computation cost of the ...

On the concrete hardness of Learning with Errors

Journal of Mathematical Cryptology, 2015
The learning with errors (LWE) problem has become a central building block of modern cryptographic constructions. This work collects and presents hardness results for concrete instances of LWE.
