PUF-Kyber: Design of a PUF-Based Kyber Architecture Benchmarked on Diverse ARM Processors
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2023 <p>In this paper, through using physical unclonable functions (PUF) and true random number generators (TRNG), we improve the overall security of CRYSTALS-Kyber and provide physical security to it. Our implementation results on ARMv7 and ARMv8 architectures indicate significant speedup, compared to the reference work.</p>

Hardness of (Semiuniform) MLWE with Short Distributions Using the Rényi Divergence
IET Information Security, Volume 2023, Issue 1, 2023., 2023 The module learning with errors (MLWE) problem has attracted considerable attention for its tradeoff between security and efficiency. The quantum/classical worst‐case to average‐case hardness for the MLWE problem (or more exactly, a family of problems) has been established, but most of the known results require the seed distribution to be the uniform ...

Hardness of Module‐LWE with Semiuniform Seeds from Module‐NTRU
IET Information Security, Volume 2023, Issue 1, 2023., 2023 The module learning with errors (MLWE) problem has attracted significant attention and has been widely used in building a multitude of lattice‐based cryptographic primitives. The hardness of the MLWE problem has been established for several variants, but most of the known results require the seed distribution (i.e., the distribution of matrix A) to be ...

Transactions on Cryptographic Hardware and Embedded Systems, 2023 In this work, we propose generic and novel adaptations to the binary Plaintext-Checking (PC) oracle based side-channel attacks for Kyber KEM. These attacks operate in a chosen-ciphertext setting, and are fairly generic and easy to mount on a given ...

High-order Table-based Conversion Algorithms and Masking Lattice-based Encryption
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Masking is the main countermeasure against side-channel attacks on embedded devices. For cryptographic algorithms that combine Boolean and arithmetic masking, one must therefore convert between the two types of masking, without leaking additional ...

NTT and Inverse NTT Quantum Circuits in CRYSTALS-Kyber for Post-Quantum Security Evaluation
Applied Sciences, 2023 The emergence of quantum computers threatens current cryptographic systems, and NIST is preparing for the post-quantum era through the post-quantum cryptography (PQC) contest. CRYSTALS-Kyber is a lattice-based cipher suite that is used as a PQC standard.
