On stabilizers in finite permutation groups
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Let G$G$ be a permutation group on the finite set Ω$\Omega$. We prove various results about partitions of Ω$\Omega$ whose stabilizers have good properties. In particular, in every solvable permutation group there is a set‐stabilizer whose orbits have length at most 6, which is best possible and answers two questions of Babai.

Preimage and pseudo-collision attacks on 29-step SM3 hash function with padding
Tongxin xuebao, 2014 The security of SM3 hash function was revaluated by using the meet-in-the-middle attack. The preimage and pseudo-collision attack on 29-step SM3 hash function (from the 1-st step) with padding was presented.

Blockweave: An Arweave‐Based Decentralized Storage Solution to Tackle the Blockchain Trilemma
Engineering Reports, Volume 7, Issue 7, July 2025.Leveraging Arweave's blockweave and Proof‐of‐Access consensus, this framework reduces on‐chain metadata to 48 bytes, enabling throughput up to 7200 TPS, 99%$$ 99\% $$ storage savings, and robust security (Q(0.4)=0.82)$$ \left(\mathrm{Q}(0.4)=0.82\right) $$ while achieving Tier‐S decentralization on $300 mining nodes.

Constructing Efficient Identity‐Based Signatures on Lattices
IET Information Security, Volume 2025, Issue 1, 2025.In this work, we explore the recent developments related to lattice‐based signature and preimage sampling, and specify a compact identity‐based signature (IBS) on an ideal lattice for practical use. Specifically, we first propose an ellipsoid version of the G + G signature scheme (Asiacrypt 2023) that achieves slightly better signature size and higher ...

Characterizing the Shape of Activation Space in Deep Neural Networks
, 2019 The representations learned by deep neural networks are difficult to interpret in part due to their large parameter space and the complexities introduced by their multi-layer structure.

International Journal of Biomedical Imaging, Volume 2025, Issue 1, 2025.Security issues of telemedicine‐based secure transmission of medical images find a very thin line drawn between diagnostic acceptability and cybersecurity. Partial but imperfect solutions emerge. JPEG2000 and HEVC concentrate only on compression, failing to provide any security consideration.

ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art
IET Blockchain, Volume 4, Issue 4, Page 423-442, December 2024.An anti‐counterfeiting system for physical art based on Ethereum blockchain and near‐field communication technology is proposed and implemented. The system leverages the use of Ethereum smart contracts and inter‐planetary file system to store artworks’ certificate of authenticity, and display them in a mobile app called ArtProtect.

A second preimage attack on zipper hash
Security and Communication Networks, 2015 AbstractThe zipper hash utilizes two‐pass hashing to strengthen the iterated hash functions against the generic attack. In this paper, we analyze the features of zipper hash and several existing generic attacks on hash functions. A new tree structure called inverse‐diamond, which starts from one fixed point and ends with many points, is exploited to ...
