Contributions to Lattice–based Cryptography

, 2023
Post–quantum cryptography (PQC) is a new and fast–growing part of Cryptography. It focuses on developing cryptographic algorithms and protocols that resist quantum adversaries (i.e., the adversaries who have access to quantum computers).

A Survey on Classical Lattice Algorithms

Cryptography
The rapid advancement of quantum computing poses a severe threat to traditional public key cryptosystems. Lattice-based cryptography has emerged as a core candidate for post-quantum cryptography due to its presumed quantum resistance, robust security ...

Higher-Order Masked Ciphertext Comparison for Lattice-Based Cryptography

Transactions on Cryptographic Hardware and Embedded Systems, 2022
Checking the equality of two arrays is a crucial building block of the Fujisaki-Okamoto transformation, and as such it is used in several post-quantum key encapsulation mechanisms including Kyber and Saber.

Generic, efficient and isochronous Gaussian sampling over the integers

Cybersecurity, 2022
Gaussian sampling over the integers is one of the fundamental building blocks of lattice-based cryptography. Among the extensively used trapdoor sampling algorithms, it is ineluctable until now. Under the influence of numerous side-channel attacks, it is

BAT: Small and Fast KEM over NTRU Lattices

Transactions on Cryptographic Hardware and Embedded Systems, 2022
We present BAT – an IND-CCA secure key encapsulation mechanism (KEM) that is based on NTRU but follows an encryption/decryption paradigm distinct from classical NTRU KEMs.
