A Novel DFA on AES: Based on Two–Byte Fault Model with Discontiguous Rows

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

DFA on AES

In this paper we describe two different DFA attacks on the AES. The first one uses a theoretical fault model that induces a fault on only one bit of an intermediate result, hence allowing us to obtain the key by using 50 faulty ciphertexts for an AES-128. The second attack uses a more realistic fault model: we assume that we may induce a fault on a whole byte. For an AES-128, this second attack...

A Fault Based Attack on MDS-AES

In this paper a fault based attack on MDS-AES has been proposed. It has been shown that inducing random byte fault at the input of the ninth round of the MDS-AES algorithm the key can be retrieved. Simulation shows that two faulty cipher text pairs are required to deduce the key without any brute-force search. If one faulty encryption is considered then the actual key can be ascertained with a ...

Piret and Quisquater's DFA on AES Revisited

At CHES 2003, Piret and Quisquater published a very efficient DFA on AES which has served as a basis for many variants published afterwards. In this paper, we revisit P&Q’s DFA on AES and we explain how this attack can be much more efficient than originally claimed. In particular, we show that only 2 (resp. 3) faulty ciphertexts allow an attacker to efficiently recover the key in the case of AE...
