A Signcryption Scheme Based Learning with Errors over Rings Without Trapdoor

2019
Signcryption has been extensively studied based on bilinear pairings, but rarely on lattices. This paper constructed a new lattice-based signcryption scheme in the random oracle model by skillfully combining a learning with errors over ring (R-LWE) based signature scheme (using the Fiat-Shamir with aborts technique) and a R-LWE based key exchange ...

Faster Number Theoretic Transform on Graphics Processors for Ring Learning with Errors Based Cryptography

2018 IEEE International Conference on Service Operations and Logistics, and Informatics (SOLI), 2018
The Number Theoretic Transform (NTT) has been revived recently by the advent of the Ring-Learning with Errors (Ring-LWE) Homomorphic Encryption (HE) schemes. In these schemes, the NTT is used to calculate the product of high degree polynomials with multi-precision coefficients in quasilinear time.

Decentralized Ciphertext-Policy Attribute-Based Encryption from Learning with Errors over Rings

2016 IEEE Trustcom/BigDataSE/ISPA, 2016
We propose a Decentralized multi-authority Ciphertext-Policy Attribute-Based Encryption (DCP-ABE) scheme, where any party can become an authority by creating a public key and generating private keys for the users by utilizing their attributes. Any user can encrypt data in terms of any monotone access structure over attributes issued from any chosen set

A Gaussian Sampler for Ring-Learning-With-Errors Scheme Reusing a Cryptographic Module

Advanced Science and Technology Letters, 2015
Since the different characteristics from the PRNG (Pseudo Random Number Generator) or various deterministic devices such as arithmetic processing units, new concepts and test methods should be suggested in order to test TRNG (Ture Random Number Generator).
