Some fault attacks such as counter and data corruption have been proposed for pairing-based cryptosystems. However, a fault model that can skip the if instruction in traditional schemes such as RSA and ECC(elliptic curve cryptosystem) does not appear in the literature in terms of pairing-based cryptography. This paper investigated the vulnerability of skipping the \emph{if} instruction in the last...
The symmetric cryptographic system such as the advanced encryption standard (AES) is a favorite target for differential fault analysis. Tunstall et al. recently proposed a fault attack in which a secret key can be extracted by injecting only a one-byte fault on the AES. Countermeasures against fault analysis have been proposed, but they have a fault detection rate limit or additional costs for extra...
This paper presents a practical differential fault analysis method for the Advanced Encryption Standard (AES) with a reduced round using a semi-invasive fault injection. We adapt the round reduction fault technique on AES in order to skip the 9-th round operation. We can deduce the AES 128-bit secret key using 216 exhaustive searches with two pairs of correct and faulty ciphertexts. We also verified...
