From Random Probing to Noisy Leakages Without Field-Size Dependence

ePrint Report: From Random Probing to Noisy Leakages Without Field-Size Dependence

Gianluca Brian, Stefan Dziembowski, Sebastian Faust

Side channel attacks are devastating attacks targeting cryptographic implementations. To protect against these attacks, various countermeasures have been proposed -- in particular, the so-called masking scheme. Masking schemes work by hiding sensitive information via secret sharing all intermediate values that occur during the evaluation of a cryptographic implementation. Over the last decade, there has been broad interest in designing and formally analyzing such …
