Modification of Frodokem Using Gray and Error-Correcting Codes

IEEE Access, 2019
Lattice-based cryptography is one of the most promising schemes for post-quantum cryptography. Among the many lattice-based cryptosystems, FrodoKEM is a well-known key-encapsulation mechanism (KEM) based on (plain) learning with errors (LWE) problems and

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.
