Unified Field Multiplier for ECC: Inherent Resistance against Horizontal SCA Attacks

Abstract

In this paper we introduce a unified field multiplier for the EC kP operation in two different types of Galois fields. The most important contributions of this paper are that the multiplier is based on the 4-segment Karatsuba multiplication method and that it is inherent resistant against selected horizontal attacks.
