Preventing Distinguishability between Multiplication and Squaring Operations

Alkistis Aikaterini Sigourou, Zoya Dyka, Peter Langendoerfer +1

Scalar multiplication kP is a critical operation in Elliptic Curve Cryptosystems (ECC), often targeted by Side-Channel Analysis (SCA). Despite strategies based on atomic patterns t…

Horizontal SCA Attacks on Binary kP Algorithms using Chevallier-Mames Atomic Blocks

Gerald Isheanesu Matungamire, Alkistis Aikaterini Sigourou, Gerrit Schrock +3

Scalar multiplication kP is the operation most frequently targeted in Elliptic Curve (EC) cryptosystems. To protect against single-trace Side-Channel Analysis (SCA) attacks, the at…

Revisiting Atomic Patterns for Elliptic Curve Scalar Multiplication Revealing Inherent Vulnerability to Simple SCA

Alkistis Aikaterini Sigourou, Zoya Dyka, Sze Hei Li +2

Elliptic Curve Scalar Multiplication denoted as kP operation is the basic operation in all Elliptic Curve based cryptographic protocols. The atomicity principle and different atomi…

Practical Investigation on the Distinguishability of Longa's Atomic Patterns

Sze Hei Li, Zoya Dyka, Alkistis Aikaterini Sigourou +2

This paper investigates the distinguishability of the atomic patterns for elliptic curve point doubling and addition operations proposed by Longa. We implemented a binary elliptic…
