ChemPhysChem, Volume 22, Issue 1, Page 40-54, January 7, 2021., 2021 Dynamic ions in small cages: The equilibrium position and dynamic behaviour of fluoride anions encapsulated in double four‐ring cages are investigated using ab initio molecular dynamics simulations. While the occurrence of local distortions depends on the framework composition, the organic cation determines whether they are randomly oriented or ordered.

Key recovery attack on Hufu-UOV
JSIAM Letters, 2022 Summary: The unbalanced oil and vinegar signature scheme (UOV) is a signature scheme whose public key is a set of quadratic polynomials over a finite field. This scheme has been considered to be secure and efficient enough under suitable parameter selections.

Side-Channel Attacks on Post-Quantum Signature Schemes based on Multivariate Quadratic Equations
Transactions on Cryptographic Hardware and Embedded Systems, 2018 In this paper, we investigate the security of Rainbow and Unbalanced Oil-and-Vinegar (UOV) signature schemes based on multivariate quadratic equations, which is one of the most promising alternatives for post-quantum signature schemes, against side ...

An Improved Identity-Based Multivariate Signature Scheme Based on Rainbow
Cryptography, 2019 Multivariate Public Key Cryptography (MPKC) is one of the main candidates for post-quantum cryptography, especially in the area of signature schemes. In this paper, we instantiate a certificate Identity-Based Signature (IBS) scheme based on Rainbow, one ...

Ultra Wideband Low‐RCS Linear Polarised Array Based on Composite Metasurface
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.The paper proposes a composite metasurface antenna. It significantly enhances the RCS reduction bandwidth compared to a single metasurface, while maintaining the antenna's radiation performance. ABSTRACT This paper proposed the design of an ultra‐wideband antenna array with low radar cross section (RCS) based on a composite metasurface.
