Fault Detection in the Advanced Encryption Standard
The AES (Advanced Encryption Standard) is an emerging private-key cryptographic system. Performance requirements in many applications, in particular in embedded systems like smart-cards, require a HW implementation of AES, for instance as a coprocessor or as a macrocell to be added to the embedded system. A HW implementation of such a cryptographic system requires in turn to consider the fault ...
متن کاملA Diagonal Fault Attack on the Advanced Encryption Standard
The present paper develops an attack on the AES algorithm, exploiting multiple byte faults in the state matrix. The work shows that inducing a random fault anywhere in one of the four diagonals of the state matrix at the input of the eighth round of the cipher leads to the deduction of the entire AES key. We also propose a more generalized fault attack which works if the fault induction does no...
متن کاملFault Based Cryptanalysis of the Advanced Encryption Standard (AES)
In this paper we describe several fault attacks on the Advanced Encryption Standard (AES). First, using optical fault induction attacks as recently publicly presented by Skorobogatov and Anderson [SA], we present an implementation independent fault attack on AES. This attack is able to determine the complete 128-bit secret key of a sealed tamper-proof smartcard by generating 128 faulty cipher t...
متن کاملDifferential Fault Analysis of the Advanced Encryption Standard
In this paper we present a differential fault attack that can be applied to the AES using a single fault. We demonstrate that when a single random byte fault is induced at the input of the eighth round, the AES key can be deduced using a two stage algorithm. The first step has a statistical expectation of reducing the possible key hypotheses to 2, and the second step to a mere 2.
متن کاملDifferential Fault Analysis of the Advanced Encryption Standard using a Single Fault
In this paper we present an enhanced Differential Fault Attack that can be applied to the AES using a single fault. We demonstrate that when a single random byte fault is induced that affects the input of the eighth round, the AES key can be deduced using a two stage algorithm. The first step, would be expected to reduce the possible key hypotheses to 2, and the second step to a mere 2. Further...
