For this purpose, most systems use block ciphers, such as the public AES standard. It is well known, however, that implementations of block ciphers such as AES, as well as other cryptographic algorithms, are subject to side-channel attacks [1]. These attacks allow adversaries to extract secret keys from devices by passively monitoring power consumption, EM emissions, or other “side channels”. Differential power analysis (DPA) is a common side channel attack that leverages power measurements.

Abstract: Previous first-order differential power analysis (DPA) attacks have depended on knowledge of the target algorithm’s input or output. This paper describes a first-order DPA attack against AES in counter mode, in which the initial counter and output values are all unknown.
