Which Chromium–Sulfur Compounds Exist as 2D Material?

Advanced Functional Materials, EarlyView.
2D chromium sulfides synthesized using molecular beam epitaxy on graphene. Structural characterization reveals two novel 2D materials, Cr2S3‐2D, which lacks a direct bulk counterpart, and Cr223S${\rm Cr}_{2\frac{2}{3}}{\rm S}$4‐2D, a minimum thickness version of Cr5S6. However, attempts to synthesize CrS2 are unsuccessful. Both new 2D phases are stable

Efficient implementation of ideal lattice-based cryptography [PDF]

it - Information Technology, 2017
Abstract Almost all practically relevant asymmetric cryptosystems like RSA or ECC are either based on the hardness of factoring or on the hardness of the discrete logarithm problem. However, both problems could be solved efficiently on a large enough quantum computer.

Lightweight Hardware Implementation of R-LWE Lattice-Based Cryptography [PDF]

2018 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2018
Lattice based cryptography (LBC) is one of the most promising post-quantum cryptographic candidates. Ring-learning with errors (R-LWE) is an encryption scheme of LBC. In this paper, a lightweight hardware implementation is presented including key generation, encryption, and decryption.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

Advanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Coding techniques in lattice-based cryptography

, 2020
Cryptographic constructions based on hard lattice problems have emerged as a front runner for the standardization of post quantum public key cryptography. The work done in this thesis introduces source and channel coding techniques to optimize specific parts of lattice-based cryptographic schemes from an information theoretic standpoint, with a ...

Soft and Stiff 3D Microstructures by Step‐Growth Photopolymerization Using a Single Photoresin and Multi‐Photon Laser Printing

Advanced Functional Materials, EarlyView.
An additive and initiator‐free photoresin based on a prepolymer decorated with photoreactive step‐growth units as crosslinkers allows for the fabrication of 3D microstructures with strongly disparate mechanical properties ranging from stiff to soft. Abstract Manufacturing three‐dimensional (3D) microstructures with multi‐material properties via two ...
