Improved Differential-neural Cryptanalysis for Round-reduced Simeck32/64

no code implementations27 Jan 2023 Liu Zhang, Jinyu Lu, Zilong Wang, Chao Li

Inspired by this framework, we develop the Inception neural network that is compatible with the round function of Simeck to improve the accuracy of the neural distinguishers, thus improving the accuracy of (9-12)-round neural distinguishers for Simeck32/64.

One Sample Diffusion Model in Projection Domain for Low-Dose CT Imaging

2 code implementations7 Dec 2022 Bin Huang, Liu Zhang, Shiyu Lu, Boyu Lin, Weiwen Wu, Qiegen Liu

Therefore, we propose a fully unsupervised one sample diffusion model (OSDM)in projection domain for low-dose CT reconstruction.

Generative Modeling in Sinogram Domain for Sparse-view CT Reconstruction

1 code implementation25 Nov 2022 Bing Guan, Cailian Yang, Liu Zhang, Shanzhou Niu, Minghui Zhang, Yuhao Wang, Weiwen Wu, Qiegen Liu

When the number of projection view changes, the DL network should be retrained with updated sparse-view/full-view CT image pairs.
