A Comparison of Chi^2-Test and Mutual Information as Distinguisher for Side-Channel Analysis
Bastian Richter, David Knichel, and Amir Moradi
Abstract
Masking is known as the most widely studied countermeasure against side-channel analysis attacks.
Since a masked implementation is based on a certain number of shares (referred to as the order of masking), it still exhibits leakages at higher orders.
In order to exploit such leakages, higher-order statistical moments individually at each order need to be estimated reflecting the higher-order attacks.
Instead, Mutual Information Analysis (MIA) known for more than 10 years avoids such a moment-based analysis by considering the entire distribution for the key recovery.
