Despite the fact that all current scientific white-box approaches of standardized cryptographic primitives have been publicly broken, these attacks require knowledge of the internal data representation used by the implementation. In practice, the level of implementation knowledge required is only attainable through significant reverse engineering efforts. In this paper we describe new approache...

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 sec...

one of the major problems that may occur in the differential protection systems of power transformers is mal-operation of the protection relays in sake of internal fault detection, because of similarity between this current and inrush current. this paper presents a novel approach for discriminating inrush current from internal fault in power transformers based on improved gravitational search a...

GIFT, a lightweight block cipher proposed at CHES2017, has been widely cryptanalyzed this years. This paper studies the differential diffusion characteristics of round function GIFT first, and proposes random nibble-based fault attack. The key recovery scheme is developed on statistical properties we found for distribution table S-box. A lot experiments had done experimental results show that o...

Although Differential Fault Analysis (DFA) led to powerful applications against public key [15] and secret key [12] cryptosystems, very few works have been published in the area of stream ciphers. In this paper, we present the first application of DFA to the software eSTREAM candidate Rabbit that leads to a full secret key recovery. We show that by modifying modular additions of the next-state ...

In this paper we present a differential fault attack on the stream cipher MICKEY 2.0 which is in eStream’s hardware portfolio. While fault attacks have already been reported against the other two eStream hardware candidates Trivium and Grain, no such analysis is known for MICKEY. Using the standard assumptions for fault attacks, we show that by injecting around 2 faults and performing 2 computa...

This paper presents an application of the adaptive median post-filter to improve impedance estimation based on the differential equation algorithm. The main feature of the post-filter is the automatic selection of the optimal window size that balances between fast tracking and filtering performance. For sudden impedance change (fault inception), small window size is selected to make fault detec...

Side channel analysis and fault attacks are two powerful methods to analyze and break cryptographic implementations. Recently, secure multiparty computation has been applied to prevent side channel attacks. While multiparty computation is known to be fault resistant as well, the particular schemes popular for side channel protection do not currently offer this feature. In this paper we introduc...

Since its first introduction by Bellcore researchers [BDL97], fault injections have been considered as a powerful and practical way to attack cryptosystems, especially when they are implemented on embedded devices. Among published attacks, Brier et al. followed the work initiated by Seifert to raise the problem of protecting RSA public elements. We describe here a new fault attack on RSA public...

Infective countermeasures have been a promising class of fault attack countermeasures. However, they have been subjected to several attacks owing to lack of formal proofs of security and improper implementations. In this paper, we first provide a formal information theoretic proof of security for one of the most recently proposed infective countermeasures against DFA, under the assumption that ...
