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(More)
Differential Fault Analysis (DFA) is a real threat for el-liptic curve cryptosystems. This paper describes an elliptic curve cryptoprocessor unit resistant against fault injection. This resistance is provided by the use of parity preserving logic gates in the operating structure of the ECC unit, which is based on borrow-save adders. The proposed(More)
— In this paper, we describe the structure of a FPGA smart card emulator. The aim of such an emulator is to improve the behaviour of the whole architecture when faults occur. Within this card, an embedded Advanced Encryption Standard (AES) protected against DFA is inserted as well as a fault injection block. We also present the microprocessor core which(More)
