Differential Behavioral Analysis

Abstract : This paper describes an attack on cryptographic devices called Differential Behavioral Analysis (or DBA). This is an hybrid attack between two already powerful attacks: differential power analysis (DPA) for the statistical treatment and safe-error attack for the fault type. DBA, simulated on an algorithmic model of AES appears to be very efficient. The attacker is able to recover the entire secret key with byte-wise \textquotedblleft stuck-at'' faults injected repetitively. A theorical as well as a more realistic approach are presented.
