In this paper we present two attacks that exploit cache events, which are visible in some side channel, to derive a secret key used in an implementation of AES. The first is an imp...
In implementing cryptographic algorithms on limited devices such as smart cards, speed and memory optimization had always been a challenge. With the advent of side channel attacks,...
While cryptographic algorithms are usually strong against mathematical attacks, their practical implementation, both in software and in hardware, opens the door to side-channel at...
Many side-channel attacks on implementations of cryptographic algorithms have been developed in recent years demonstrating the ease of extracting the secret key. In response, vari...

Differential Power Analysis (DPA) is a powerful side channel key recovery attack that efficiently breaks block ciphers implementations. In software, two main techniques are usually...
