ePrint Report: Prime Masking vs. Faults - Exponential Security Amplification against Selected Classes of Attacks

Thorben Moos, Sayandeep Saha, François-Xavier Standaert

Fault injection attacks are a serious concern for cryptographic hardware. Adversaries may extract sensitive information from the faulty output that is produced by a cryptographic circuit after actively disturbing its computation. Alternatively, the information whether an output would have been faulty, even if it is withheld from being released, may be exploited. The former class of attacks, which requires …
