Improved High-Order Masked Generation of Masking Vector and Rejection Sampling in Dilithium [PDF]

Transactions on Cryptographic Hardware and Embedded Systems
for Dilithium, the post-quantum signature scheme recently standardized by NIST. We improve the masked generation of the masking vector y, based on a fast Booleanto- arithmetic conversion modulo q.

Falcon/Kyber and Dilithium/Kyber Network Stack on Nvidia’s Data Processing Unit Platform

IEEE Access
Commercially available quantum computers are expected to reshape the world in the near future. They are said to break conventional cryptographic security mechanisms that are deeply embedded in our today’s communication.

PACE—Plantard Accelerated CRYSTALS Extensions

IEEE Access
ML-KEM (FIPS203) and ML-DSA (FIPS204) were two of the first post quantum cry- ptography schemes to be standardized by the National Institute of Standards and Technology; Both CRYSTALS algorithms utilize modulo reduction, specifically Montgomery reduction.

Dilithium manganese(II) catena-tetrakis(polyphosphate), Li2Mn(PO3)4

Acta Crystallographica Section E, 2014
The poly-phosphate Li2Mn(PO3)4 was synthesized and its structure characterized from powder diffraction data by Averbuch-Pouchot & Durif [J. Appl. Cryst. (1972), 5, 307–308]. These authors showed that the structure of this phosphate is isotypic to that of

Rejected Signatures’ Challenges Pose New Challenges: Key Recovery of CRYSTALS-Dilithium via Side-Channel Attacks

Transactions on Cryptographic Hardware and Embedded Systems
Rejection sampling is a crucial security mechanism in lattice-based signature schemes that follow the Fiat-Shamir with aborts paradigm, such as MLDSA/ CRYSTALS-Dilithium.

Speedup signing: pre-rejection sampling towards dilithium

Cybersecurity
Security and efficiency have always been two critical factors in the development of post-quantum digital signatures. As the best-known scheme, Dilithium (Ducas et al., TCHES 2018) is SUF-CMA in QROM and has a relatively fast efficiency with many ...

Multiplying Polynomials without Powerful Multiplication Instructions

Transactions on Cryptographic Hardware and Embedded Systems
We improve the performance of lattice-based cryptosystems Dilithium on Cortex-M3 with expensive multiplications. Our contribution is two-fold: (i) We generalize Barrett multiplication and show that the resulting shape-independent modular multiplication ...

Pentapotassium praseodymium(III) dilithium decafluoride, K5PrLi2F10

Acta Crystallographica Section E, 2009
The crystal structure of K5PrLi2F10 is isotypic with those of other K5RELi2F10 compounds (RE = Eu, Nd). The lanthanoid ions are isolated in K5PrLi2F10, with a mean separation between the Pr ions of 7.356 Å.
