TLDR
This paper presents an efficient trace-driven cache attack on a widely used implementation of the AES cryptosystem, and develops an accurate mathematical model that is used in the cost analysis of the attack.Abstract:
Cache based side-channel attacks have recently been attracted significant attention due to the new developments in the field. In this paper, we present an efficient trace-driven cache attack on a widely used implementation of the AES cryptosystem. We also evaluate the cost of the proposed attack in detail under the assumption of a noiseless environment. We develop an accurate mathematical model that we use in the cost analysis of our attack. 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.read more

Seer: A Lightweight Online Failure Prediction Approach
Burcu Ozcelik,Cemal Yilmaz +1 more
TL;DR: It is conjecture that large cost reductions in collecting internal execution data for online failure prediction may derive from pushing the substantial parts of the data collection work onto the hardware.

Cache-collision timing attacks against AES
Joseph Bonneau,Ilya Mironov +1 more
TL;DR: The most powerful attack has been shown under optimal conditions to reliably recover a full 128-bit AES key with 213 timing samples, an improvement of almost four orders of magnitude over the best previously published attacks of this type.
