Lattice-Based proof of a shuffle [PDF]
, 2019 In this paper we present the first fully post-quantum proof of a shuffle for RLWE encryption schemes. Shuffles are commonly used to construct mixing networks (mix-nets), a key element to ensure anonymity in many applications such as electronic voting ...

Physical Protection of Lattice-Based Cryptography [PDF]
Proceedings of the 2018 Great Lakes Symposium on VLSI, 2018 The impending realization of scalable quantum computers will have a significant impact on today's security infrastructure. With the advent of powerful quantum computers public key cryptographic schemes will become vulnerable to Shor's quantum algorithm, undermining the security current communications systems.

Not-so-adiabatic quantum computation for the shortest vector problem
Physical Review Research, 2020 Since quantum computers are known to break the vast majority of currently used cryptographic protocols, a variety of new protocols are being developed that are conjectured, but not proved, to be safe against quantum attacks.

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

A new exact closest lattice point search algorithm using linear constraints [PDF]
, 2007 The problem of finding the closest lattice point arises in several communications scenarios and is known to be NP-hard. We propose a new closest lattice point search algorithm which utilizes a set of new linear inequality constraints to reduce the search

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.
