White-box filtering attacks breaking SEL masking: from exponential to polynomial time

ePrint Report: White-box filtering attacks breaking SEL masking: from exponential to polynomial time

Alex Charlès, Aleksei Udovenko

This work proposes a new white-box attack technique called filtering, which can be combined with any other trace-based attack method. The idea is to filter the traces based on the value of an intermediate variable in the implementation, aiming to fix a share of a sensitive value and degrade the security of an involved masking scheme.


Coupled with LDA (filtered LDA, FLDA), it …
