Side-channel attacks have proven many hardware implementations of cryptographic
algorithms to be vulnerable. A recently proposed masking method, based on secret sharing
and multi-party computation methods, introduces a set of sufficient requirements for
implementations to be provably resistant against first-order DPA with minimal assumptions
on the hardware. The original paper doesn't describe how to construct the Boolean functions
that are to be used in the implementation. In this paper, we derive the functions for all …
