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

On the Efficiency of Software Implementations of Lightweight Block Ciphers from the Perspective of Programming Languages.
TL;DR: This is the first attempt to benchmark various software implementations of a single lightweight block cipher across different programming languages and platforms in the cloud architecture and showed that these choices can affect the efficiency of a cryptographic primitive by a factor as high as 400.

Improved Trace-Driven Cache-Collision Attacks against Embedded AES Implementations.
TL;DR: In this paper, the authors presented two attacks that exploit cache events, which are visible in some side channel, to derive a secret key used in an implementation of AES, which is comparable to classical Dierential Power Analysis; however, their attacks are able to overcome certain masking techniques.

Cache Side-Channel Attacks: Flush+Flush and the Countermeasures Time Gap
TL;DR: The experiment results indicate that the shared memory of computer applications may be vulnerable to cache side-channel attacks and that more work needs to be done to protect users in the cloud computing system in this aspect.

Timing Attacks on Implementations of Diffie-Hellman, RSA, DSS, and Other Systems
TL;DR: By carefully measuring the amount of time required to perform private key operalions, attackers may be able to find fixed Diffie-Hellman exponents, factor RSA keys, and break other cryptosystems.

Cache attacks and countermeasures: the case of AES
TL;DR: In this article, the authors describe side-channel attacks based on inter-process leakage through the state of the CPU's memory cache, which can be used for cryptanalysis of cryptographic primitives that employ data-dependent table lookups.

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.
