In this paper, we present an examination of several side-channel attack scenarios on PC-based cryptosystems. Our goal was the development of a unified physical model for sensitive information leakage. The main focus of our work was electromagnetic side channels since signals with high signal-to-noise ratio (SNR) can be more conveniently captured. Moreover, the attacker can make correlations of the...
Most modern devices and cryptoalgorithms are vulnerable to a new class of attack called side-channel attack. It analyses physical parameters of the system in order to get secret key. Most spread techniques are simple and differential power attacks with combination of statistical tools. Few studies cover using machine learning methods for pre-processing and key classification tasks. In this paper,...
Authentication in GSM networks uses COMP128, which is vulnerable to side-channel attack called partitioning attack. On the device constrained in resources, such as SIM-card, table lookups are quite unreliable, so the attack can be carried out using up to 1000 queries. Proposed method — combined side-channel attack — can speed up key retrieving. Partitioning attack measures only power consumption,...
