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 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.

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.

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 ...

Masked Accelerators and Instruction Set Extensions for Post-Quantum Cryptography
Transactions on Cryptographic Hardware and Embedded Systems, 2021 Side-channel attacks can break mathematically secure cryptographic systems leading to a major concern in applied cryptography. While the cryptanalysis and security evaluation of Post-Quantum Cryptography (PQC) have already received an increasing research

[sic], 2016 Između ponoći i jednog sata oživi sve ono za što glupi ljudi vjeruju da oživjeti ne može. Ali zaista, mnogobrojne stvari koje inače samo ukočeno i mirno leže, kao da ne mogu reći ni „dobar dan“, sve one u to vrijeme ožive. I ne brinu mnogo o tome vjeruju

Frontiers in PhysicsCritical infrastructures increasingly rely on AI-generated content (AIGC) for monitoring, decision support, and autonomous control. This dependence creates new attack surfaces: forged maintenance imagery, manipulated diagnostic scans, or spoofed sensor ...

The security of Kyber's FO-transform.
IACR Cryptol. ePrint Arch., 2023 In this short note we give another direct proof for the variant of the FO transform used by Kyber in the QROM. At PKC'23 Maram & Xagawa gave the first direct proof which does not require the indirection via FO with explicit rejection, thereby avoiding either a non-tight bound, or the necessity to analyze the failure probability in a new setting ...
