According to the Snowden documents, the NSA is doing research on whether a cryptographic attack based on tau statistic may help to break AES
Pearson correlation coefficient is a measure of the linear correlation between two variables X and Y
It's somehow straightforward to think at the variables in this statement like the variables in linear cryptanalysis... is this correct?
Is the application of Kendall's tau a sort of power-up of Linear Cryptanalysis? How?
