Consolidating masking schemes

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.
