Title:
Consolidating masking schemes

Authors: Oscar Reparaz, Begül Bilgin, Svetla Nikova, Benedikt Gierlichs, Ingrid Verbauwhede

Abstract:

In this paper we investigate relations between several masking schemes. We show that the Ishai–Sahai–Wagner private circuits construction is closely related to Threshold Implementations and the Trichina gate. The implications of this observation are manifold. We point out a higher-order weakness in higher-order Threshold Implementations, suggest a mitigation and provide new sharings that use a lower number of input shares.
