Cyclotomic Polynomials in Ring-LWE Homomorphic Encryption Schemes

, 2016
Homomorphic Encryption has been considered the \u27Holy Grail of Cryptography\u27 since the discovery of secure public key cryptography in the 1970s. In 2009, a long-standing question about whether fully homomorphic encryption is theoretically plausible ...

A Central Limit Approach for Ring-LWE Noise Analysis

IACR Communications in Cryptology
This paper develops Central Limit arguments for analysing the noise in ciphertexts in two homomorphic encryption schemes that are based on Ring-LWE. The first main contribution of this paper is to present and evaluate an average-case noise analysis for the BGV scheme.

Lattice-Based CP-ABE Access Control for SDS Constraint with Lazy Assignment of Attributes and Attribute Revocation

IET Information Security
Ciphertext-policy attribute-based encryption (CP-ABE) is a cryptographic scheme suitable for secure data sharing on cloud storage. The CP-ABE based on lattice theory has the property of resisting quantum attack. Some data objects uploaded to the cloud by

A Simple Key Reuse Attack on LWE and Ring LWE Encryption Schemes as Key Encapsulation Mechanisms (KEMs) [PDF]

, 2019
In this paper, we present a simple attack on LWE and Ring LWE encryption schemes used directly as Key Encapsulation Mechanisms (KEMs). This attack could work due to the fact that a key mismatch in a KEM is accessible to an adversary. Our method clearly

Implementing a Toolkit for Ring-LWE Based Cryptography in Arbitrary Cyclotomic Number Fields [PDF]

, 2016
Recent research in the field of lattice-based cryptography, especially on the topic of the ring-based primitive ring-LWE, provided efficient and practical ring-based cryptographic schemes, which can compete with more traditional number-theoretic ones. In
