High-Performance Hardware Implementation of CRYSTALS-Dilithium [PDF]

, 2021
Many currently deployed public-key cryptosystems are based on the difficulty of the discrete logarithm and integer factorization problems. However, given an adequately sized quantum computer, these problems can be solved in polynomial time as a function ...

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 ...

Extended Cycle Life in Lithium‐Ion Batteries through Lithium Supplementation from Li2C4O4@SiO2 Microcapsules

Batteries &Supercaps, Volume 9, Issue 1, January 2026.
The use of Li2C4O4@SiO2 microcapsules, in which Li2C4O4 serves as an additional source of lithium ions and the porous SiO2 shell shields direct contact between the active material and Li2C4O4, enables an additional supply of lithium ions in the battery cell.

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.

Homogenization‐confined‐repair regeneration of spent LiFePO4 cathodes via tunable pre‐oxidization and microencapsulation strategy

InfoMat, Volume 8, Issue 1, January 2026.
The HCR‐DR method combines pre‐oxidation and NIPS to synchronize atomic defect repair with structural engineering. Pre‐oxidation converts S‐LFP into stoichiometric intermediates, eliminating residual binder and carbon. Ethanol‐induced NIPS of PVA forms porous microcapsules with confined Li2CO3/glucose around S‐LFP‐Air particles. Annealing pyrolyzes PVA
