Trace-Driven Cache Attacks on AES

Authors: Onur Ac\i{}içmez, Çetin Kaya Koç


Cache based side-channel attacks have recently been attracted significant attention due to the new developments in the field. In this paper, we present efficient trace-driven cache attacks on a widely used implementation of the AES cryptosystem. We also evaluate the cost of the proposed attacks in detail under the assumption of a noiseless environment. We develop an accurate mathematical model that we use in the cost analysis of our attacks. We use two different metrics, specifically, the expected number of necessary traces and the cost of the analysis phase, for the cost evaluation purposes. Each of these metrics represents the cost of a different phase of the attack.
