A note on the security of Higher-Order Threshold Implementations

Oscar Reparaz

Abstract

At ASIACRYPT 2014, Bilgin et al. describe higher-order threshold implementations: a masking countermeasure claiming resistance against higher-order differential power analysis attacks. In this note, we point out that higher-order threshold implementations do not necessarily provide higher-order security. We give as counterexamples two concrete higher-order threshold implementations that exhibit a second order flaw.
