چکیده

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. Furthermore, we show that, with certain faults, this can be further reduced to two key hypotheses.

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.

Differential 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.

Differential 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...

Implementation 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...

transformer differential protection using the fault-generated high-frequency transient components

Power transformers are the most important components of a power system, so their protection is a critical issue. This paper proposes a novel and efficient algorithm based on the high-frequency components of the differential current signal to discriminate between the magnetizing inrush currents and the internal faults. After detecting the over-current in the differential current signals, samples...
