Differential Fault Analysis of the Advanced Encryption Standard
نویسنده
چکیده
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.

Acceleration of Differential Fault Analysis of the Advanced Encryption Standard Using Single Fault
In this paper we present a speed up of the existing fault attack [2] on the Advanced Encryption Standard (AES) using single faulty cipher. The paper suggests a parallelization technique to reduce the complexity of the attack from 2 to 2.
متن کاملImplementation of Combinational Logic S-Box and Its Fault Detection for Advanced Encryption Standard Algorithm
Fault attacks are going on increasing with high data transfers so powerful and efficient cryptanalysis techniques are required to reduce the fault attacks. Such a technique is Advanced Encryption Standard (AES) algorithm. These attacks are based on injecting faults into the structure of the AES to obtain the confidential information. To protect the AES implementation against these attacks, a nu...
متن کاملDifferential Fault Analysis of AES using a Single Multiple-Byte Fault
In this paper we present an improved fault attack on the Advanced Encryption Standard (AES). This paper presents an improvement on a recently published differential fault analysis of AES that requires one fault to recover the secret key being used. This attack requires that one byte entering into the eighth round is corrupted. We show that the attack is possible where more than one byte has bee...
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...
متن کاملDifferential Fault Analysis Attack Resistant Architectures for the Advanced Encryption Standard
We present two architectures for protecting a hardware implementation of AES against side-channel attacks known as Differential Fault Analysis attacks. The first architecture, which is efficient for faults of higher multiplicity, partitions the design into linear (XOR gates only) and nonlinear blocks and uses different protection schemes for these blocks. We protect the linear blocks with linea...
