A neural distinguisher is a deep learning-based tool used in cryptanalysis to differentiate between ciphertexts (or intermediate states) generated by a real cipher and those generated by a random function. Key Idea: Instead of using traditional statistical methods to detect cryptographic weaknesses (like differential or linear cryptanalysis), a neural network is trained to distinguish real cipher outputs from random data. If the neural network can do so with accuracy significantly better than random guessing (i.e., >50%), it implies that the cipher has detectable patterns or weaknesses. How It Works: Data Collection: Generate labeled data – outputs from the real cipher (label 1) and from a random permutation or round-reduced version (label 0). Model Training: Train a neu...

...paper's quality and navigate the submission journey. Abstract : This work explores population growth trends and mortality proportions among people with non-communicable diseases in this context. Population, growth rate and estimates of non-communicable disease deaths from 1980 to 2024 have been extracted from the World Bank and World Health Organization statistical databases. After employing the linear regression for imputing missing values in the exploratory data analysis, the correlation analysis and the statistical tests showed a direct relationship between population and non-communicable disease deaths and an inverse relationship between growth rate and non-communicable disease deaths. Regression analysis supported this conclusion, revealing that the test carried a pr...
