Online Template Attacks
TL;DR: It is shown that online template attacks need only one power consumption trace of a scalar multiplication on the target device and are suitable not only against ECDSA and static elliptic curve Diffie–Hellman (ECDH), but also against elliptic Curve scalar multiplied in ephemeral ECDH.
Proceedings ArticleDOI
Strength in Numbers: Improving Generalization with Ensembles in Machine Learning-based Profiled Side-channel Analysis
TL;DR: This paper discusses how output class probabilities represent a strong metric when conducting the side-channel analysis and shows how ensembles of machine learning models based on averaged class probabilities can improve generalization.
Proceedings ArticleDOI
On using genetic algorithms for intrinsic side-channel resistance: the case of AES S-box
TL;DR: The results of the experiments proved the feasibility of finding S-boxes with the desired properties in the case of AES, and preliminary results of side-channel experiments on different versions of "improved" S- boxes are shown.
Book ChapterDOI
Online Template Attacks
TL;DR: It is shown that OTA need only one power consumption trace of a scalar multiplication on the target device; they are thus suitable not only against ECDSA and static Diffie-Hellman, but also against elliptic-curve scalarmultiplication in ephemeral Diffie -Hellman.
Book ChapterDOI
Applying Horizontal Clustering Side-Channel Attacks on Embedded ECC Implementations
TL;DR: Well known countermeasures like regularity, projective coordinates and scalar randomization are used to harden implementations against common side-channel attacks like DPA.
